Common air pollutants like ozone and nitric oxide can alter the scent of ants, triggering aggressive behavior from nestmates who perceive them as intruders.
Ants rely on scent for social recognition, and when they encounter individuals with unfamiliar scents, they often react with aggression—biting or even killing the perceived invader. Notably, ozone—a greenhouse gas emitted from vehicle exhaust and industrial processes—can impact the chemical makeup of alkenes, compounds important to the unique scent profile of their colony.
Markus Knaden and researchers at the Max Planck Institute for Chemical Ecology in Jena, Germany, previously noted that ozone-induced changes in alkenes can disrupt insect communication, leading to phenomena such as fruit flies mating with inappropriate partners or pollinators like the tobacco moth losing interest in flowers. But how does ozone affect ant behavior?
To explore this, Knaden’s team established artificial colonies of six ant species, exposing them to glass chambers with varied ozone concentrations, mirroring summer levels recorded in Jena. Upon their return, the subjected ants faced attacks from their colony members.
“I honestly didn’t expect this outcome,” Knaden remarked. “We anticipated the ozone might alter just a small fraction—2 to 5 percent—of the overall scent blend.”
In natural settings, such aggressive behavior can hinder colony efficiency, even without any fatalities among the ants, though it is complex to design experiments that effectively measure these impacts.
Daniel Cronauer, a professor at Rockefeller University in New York, commented that the aggression observed is not surprising given the crucial role alkenes play in identifying nestmates.
Alkenes also facilitate other vital ant behaviors, including tracking via footprints and communication between larvae and adults. This study indicates that ozone exposure may lead clonal ant adults (Oseraea Billoi) to neglect their larvae, suggesting that these changes could disrupt various facets of ant life and potentially affect broader ecosystem dynamics.
“In most terrestrial ecosystems, the removal of ants would likely lead to catastrophic consequences,” Cronauer stated. Ants are pivotal for dispersing seeds, aerating soil, and fostering symbiotic relationships with other species.
With global insect populations in decline, this research adds to a growing body of evidence linking air pollution to these declines. Knaden asserts that while current ozone levels may not pose immediate dangers to humans, “we must acknowledge the unseen consequences of our actions.”

Innovative vaccines may provide a new approach to combat severe food allergies
Tartesy / Alamy
Researchers have developed an experimental vaccine that successfully protects mice from anaphylaxis, a potentially life-threatening allergic reaction, for at least one year. There is optimism that this vaccine will also be effective in humans.
Anaphylaxis poses a persistent threat to millions worldwide, particularly for individuals allergic to foods like peanuts and shellfish. In the UK alone, around 6% of adults, or about 2.4 million people, are believed to have clinically confirmed food allergies.
Allergic reactions can occur from consuming contaminated food or even from kissing someone who has recently eaten the allergenic food. This triggers a surge of immunoglobulin E (IgE) antibodies, leading to symptoms such as throat swelling, breathing difficulties, and a drop in blood pressure. Despite having an epinephrine auto-injector (like an EpiPen) at hand, many still need emergency treatment, and severe cases may be fatal.
Currently, avoiding allergens is the primary method of prevention, with limited alternatives available. Individuals can consider oral immunotherapy, where the allergen is gradually introduced under supervision to build up tolerance. There is also an anti-IgE monoclonal antibody drug, like omalizumab, which binds to IgE to block allergic responses. However, omalizumab is costly and requires injections every few weeks, sometimes indefinitely.
Recently, Laurent Reber and colleagues at the Toulouse Institute of Infection and Inflammation in France developed a vaccine named IgE-K. This vaccine encourages the immune system to produce antibodies that target IgE, preventing it from attaching to receptors on immune cells and averting severe allergic reactions.
“Our goal was to create a long-term solution, as individuals with food allergies face unintentional exposure at any time, necessitating ongoing protection,” says Reber.
In experiments with mice engineered to produce the human variant of IgE, the team discovered that two doses of the vaccine led to the generation of neutralizing antibodies against IgE.
“It blocks the molecules responsible for allergic reactions,” says Josh Koenig from McMaster University in Ontario, Canada.
Upon exposing the mice to a substance that triggered an allergic reaction, the unvaccinated mice experienced significant reactions, while the vaccinated mice exhibited no symptoms and were shielded from anaphylaxis for up to a year.
“It might last longer, but we have yet to conduct further testing,” noted Reber.
IgE forms part of the immune system, activated in response to toxins and certain intestinal parasites apart from allergens. “This mechanism is likely an evolutionary adaptation to combat toxins,” suggests Lever.
Lever asserts there is strong evidence supporting the long-term safety of targeting this molecule, as many individuals with severe allergies have been on anti-IgE therapy for years without negative effects. To assess if reducing IgE would diminish the body’s protective response to parasites, further tests were conducted on mice. The results indicated that the vaccine did not hinder their immune response to infections involving mouse feline, a parasitic nematode.
Koenig expresses hope regarding the vaccine’s efficacy in humans. “Research shows that the mouse-generated antibodies attach effectively to human IgE molecules. If humans can produce similar antibodies, there’s a promising chance it will be highly effective.”
Despite this optimism, Lever emphasizes that clinical trials are necessary to assess the vaccine’s safety, effectiveness, and duration in humans. If it can be commercialized, it may provide a cost-effective treatment alternative for individuals with severe allergies, requiring far fewer injections than anti-IgE monoclonal antibodies such as omalizumab.
Three councils in London have experienced cyberattacks, leading to the activation of emergency plans to determine if any data was compromised.
The Royal Boroughs of Kensington and Chelsea, which share portions of their IT infrastructure, along with Westminster City Council, reported that several systems, including telephone communications, were impacted across both councils. As a precaution, the city council disabled several computer systems to prevent additional harm.
The Information Commissioner’s Office confirmed that the London borough of Hammersmith and Fulham also reported being affected by the attack. Collectively, these three councils serve over 500,000 residents in London. In 2020, Hackney City Council was hit by a ransomware attack that encrypted 440,000 files, leading to disciplinary measures from the ICO.
Engineers from RBKC worked tirelessly through Monday and Tuesday to address the incident. They noted that services such as checking council tax bills and paying parking fines could face restrictions, and the website might be temporarily suspended on Wednesday while security measures are implemented.
In a statement from the council, it was mentioned: “We do not have all the answers yet, as we are still managing this incident. However, we are aware that there are concerns among the public, and we will provide updates to our residents and partners in the coming days. At this point, it is too early to determine the perpetrator or motive, but we are investigating whether any data may have been compromised. This is standard procedure.”
The agency and the City of Westminster have stated they are collaborating with cyber incident specialists and the National Cyber Security Center, focusing on safeguarding systems and data, restoring systems, and sustaining essential public services.
These boroughs share some IT resources with Hammersmith and Fulham, and it remains unclear how significantly they were impacted.
RBKC added: “We have activated our business continuity and emergency protocols to ensure that we can continue providing vital services to our residents, especially for the most vulnerable.”
Westminster City Council shared in a statement: “We apologize for any inconvenience to our residents and appreciate your patience and understanding. There may be delays in our responses and services over the coming days. We are committed to working closely with our cyber experts and the NCSC to restore all systems promptly. We will inform you as soon as more details become available, and we strive to keep you updated on any service changes.”
The incident was identified on Monday morning, raising concerns in other councils. Hackney, located in east London and previously affected by a land survey, housing, and planning services disruption in 2020, stated to its staff: “We have received reports that several London councils have been targeted by cyber-attacks in the last 24 to 48 hours, which could cause disruptions to their systems and services.”
Rob Miller, former IT director at Hackney City Council and now senior director at consultancy Public Digital, remarked: “When such an event occurs, you feel an immediate sense of dread as you realize the challenges in getting everything back on track. It’s an incredibly distressing experience.”
The foremost AI institute in Britain has declared a new initiative to safeguard the nation from cyber assaults targeting essential services such as energy, transportation, and utilities. This announcement follows the resignation of its chief executive, who stepped down amid pressure from government officials over allegations of a detrimental workplace environment.
On Tuesday, the Alan Turing Institute revealed that it will “launch a program of science and innovation focused on shielding the UK from hostile threats.” This initiative is part of a broader reorganization following the resignation of CEO Jean Innes last month, which came after staff discontent and the government’s directive for a state-sponsored strategic review of the institution.
This mission arises from escalating worries about online disruptions and the UK’s susceptibility to cyberattacks, particularly in light of recent incidents that impacted Amazon’s cloud operations globally, along with cyberattacks that disrupted production at Jaguar Land Rover’s facility and influenced the supply chains of Marks & Spencer and Co-op.
Bryce Crawford, the former leader of the UK Air and Space Warfare Center, is expected to deliver a report next month addressing how government-supported research institutes can “enhance the scale of the government’s AI goals in defense, national security, and intelligence.”
Chairman Doug Garr, a former president of Amazon UK, disclosed that 78 different research initiatives at the 440-member institute have been shut down, transferred, or completed due to misalignment with the new trajectory.
The institute has experienced significant internal conflict since last year as staff opposed the proposed changes, leading to a group of employees submitting a whistleblower complaint to the Charity Commission.
In a BBC interview, Garr stated that the allegations from the whistleblower were “independently investigated” by an external entity and deemed “without merit.”
Named after the mathematical pioneer who played a crucial role in decoding the Enigma machine during World War II, the institute is associated with key concepts of AI and is also known for the Turing Test, which evaluates whether computers can demonstrate human-like intelligence.
The institute will additionally emphasize applying AI to environmental and health challenges. Leveraging rapidly evolving technology, it aims to create faster and more precise methods to forecast shifts in weather, oceans, and sea ice, aiding UK government endeavors to enhance the readiness of emergency responders. Furthermore, it seeks “measurable reductions in emissions across transportation networks, manufacturing processes, and critical infrastructure.”
In the health sector, it will prioritize the creation of a digital twin of the human heart, pushing forward in AI-enabled personalized medicine to potentially enhance medical interventions and improve outcomes for patients with severe heart conditions.
Combination Asthma Inhalers are likely the best treatment choice for individuals of all ages
sbdigit/getty images
Inhalers, providing both immediate and long-term relief, are already the standard treatment for mild asthma among individuals over 12 in the UK, US, and other regions. A recent study involving nearly 400 children in New Zealand indicates these inhalers are even more effective for younger kids, nearly halving the number of asthma attacks.
Team members have stated that whether these findings will prompt changes in national and international guidelines remains uncertain. Andy Bush from Imperial College London asserts that the evidence is compelling. “If you’re a child with asthma, I have those combinations,” he remarks.
The traditional treatment for mild asthma involved an inhaler containing salbutamol, which relaxes airway muscles for about 3-4 hours. These “rescue” inhalers were to be used as needed.
If the rescue inhaler was inadequate, patients were provided with a separate inhaler containing steroids that help reduce inflammation caused by asthma. These “preventive” inhalers required regular usage to ensure protective benefits. Bush comments, “Previously, I had to take inhaled steroids twice a day for them to work, but it’s now evident that’s not always necessary.”
Studies involving teenagers and adults have indicated that combination inhalers outperform the previous treatment method, even when used on an as-needed basis. The steroids found in these combination inhalers are budesonide, while the reliever is formoterol, which acts similarly to salbutamol but lasts for 12 hours.
Concerns regarding the use of combination inhalers by children have emerged due to potential growth effects from steroid components; however, the latest research showed no negative impact during the trial period. The study involved 360 children randomly assigned to use either budesonide-fluticasone or steroid fluticasone twice daily, with additional relief administered as required during severe asthma episodes.
In other studies, the use of combination inhalers led to a decrease in overall steroid intake, according to Bush. This is because using the inhalers on an as-needed basis causes the dosage of inhaled steroids to adapt according to symptom severity. Fewer attacks mean fewer individuals need to “step up” to the combination inhaler two times daily or rely on steroid pills.
Recent reports indicate an increasing risk of assaults on submarine cables supported by Russia and China, which facilitate international internet traffic, particularly amid ongoing tensions in the Baltic Sea and Taiwan.
Submarine cables represent 99% of global intercontinental data traffic and have experienced various disruptive incidents allegedly tied to state activities in the past 18 months.
A study conducted by the US cybersecurity firm Recorded Future has highlighted nine incidents expected in the Baltic Sea and near Taiwan in 2024 and 2025, suggesting a predictive pattern for further harmful actions.
According to the analysis, while genuine accidents could lead to damage to many submarine cables, the situations in the Baltic Sea and Taiwan suggest a rise in malicious actions attributed to Russia and China.
“The operations linked to Russia in the Baltic region and China in the Western Pacific are likely to increase as tensions elevate,” the firm noted.
The report points to several incidents, including the disconnection of two submarine cables from Lithuania to Sweden in November, with accusations directed at an anchor dragged by a Chinese vessel. Also in December, a Russian oil tanker was detained after severing cables between Finland and Estonia.
In Taiwan, recent incidents include cable damage caused by a Chinese-operated cargo vessel zigzagging over the line to Peng Island in February. One month prior, another Chinese vessel was suggested as a likely source of damage to the Taiwan-US cable.
The analysis states, “While deterring state-sponsored sabotage linked to the Baltic and Taiwan incidents is challenging, such activities align with the strategic goals of Russia and China, as well as observed operations and their existing deep-sea capabilities.”
Recorded Future emphasizes that successful attacks on multiple cables are likely to result in prolonged disruptions, typically requiring intervention in deeper waters and likely involving state-level threat actors due to the complexities of accessing these sites. Such actions may occur prior to a full-scale conflict, the report suggests.
The firm noted 44 distinct cable damages have been recorded over the past 18 months. A significant portion is attributed to “unclear causes,” while nearly a third remains unexplained, with 16% due to seismic activity or other natural events.

Analysts believe that targeting subsea cables presents a strategic advantage, as such actions can disguise as accidental damage or implicate vessels without direct connections to any suspected attackers.
To mitigate the risk of incidents damaging multiple cables and resulting in “long-term connectivity issues,” Recorded Future recommends enhanced cable monitoring, improved security measures, and robust stress testing of subsea infrastructure.
Notably, despite incidents in the Baltic and Taiwan regions, the most severe cases unfolded elsewhere. In February last year, a missile from Houthi forces struck a ship’s anchor, severely disrupting communications in the Middle East. A month later, in West Africa, an underwater landslide caused significant issues, followed by another critical incident off the coast of South Africa in May 2024 related to cable drifting.
The implications of the Red Sea and African incidents reveal that the longest-lasting disruptions occur in regions with limited alternative cable options and insufficient repair capabilities, irrespective of the specific causes.
In contrast, two cable incidents in the Baltic Sea last November had minimal repercussions due to their relatively low impact and the resilience of European internet infrastructure. However, the report highlights that three EU island nations—Malta, Cyprus, and Ireland—are more susceptible due to their heavy dependence on submarine cables for global communications.
The recent strategic defense assessment from the UK government acknowledged the potential threats to submarine cables and recommended a greater and more coordinated role for the Royal Navy in safeguarding the submarine infrastructure that carries vital information, energy, and goods relied upon by citizens.
A third of Australian homes feature rooftop solar panels

Power grids across the globe face an increasing risk of cyberattacks, primarily due to the vulnerabilities inherent in home solar equipment.
With the rise of distributed energy resources like rooftop solar, grids are leaning more heavily on smart inverters that control connections to local power networks.
“While these technologies provide numerous advantages, they also bring forth new operational and cybersecurity hurdles,” says Sid Chau, a researcher at CSIRO, the Australian government’s research institute.
Smart inverters convert the direct current generated by solar panels into the alternating current required by electrical devices. They also optimize energy storage and enable remote monitoring via the Internet.
This web connectivity means that they not only jeopardize home solar installations but can also threaten larger power generation networks, warn Chau and his team.
The team has pinpointed various methods through which smart inverters can be compromised, including exploiting hardware and software vulnerabilities. Hackers can deceive users into granting excessive permissions on connected inverter applications or collaborate with manufacturers to embed malicious code directly into hardware.
Chau and his team modeled the threats stemming solely from Australian inverters, where roughly one-third of residences possess rooftop solar systems. This scenario mirrors certain power grids worldwide where civilian solar installations are becoming increasingly prevalent.
Although such attacks necessitate careful planning and coordination, researchers have discovered that a relatively small number of compromised solar smart inverters can create significant disruptions when vulnerabilities align.
Once a smart inverter is infiltrated, hackers can execute synchronized attacks targeting the broader power grid.
Of particular concern are assaults aimed at the frequency control of the power grid. In regions like Australia and Europe, the grid frequency must maintain around 50 HERTZ. Though safeguards exist, deviations can lead to cascading failures within the power system.
The risk is heightened further by the long lifespan of many inverters, often exceeding 15 years, which allows cybersecurity measures to quickly become outdated.
Chau emphasizes the need for improved monitoring of private inverters so that authorities can promptly address any suspicious activities that arise.
He also advocates for enhanced long-term support for inverter owners and regular compliance checks to guarantee adherence to cybersecurity and maintenance standards.
Zubair Baig from Deakin University in Melbourne stresses the importance of security validation for all imported inverters.
“Since these devices are often not produced domestically, there exists a risk that they might be configured with malware during manufacturing, leading to potential current fluctuations, permanent equipment damage, and even grid failure,” states Baig.
Ernest Foo from Griffith University in Brisbane highlights that Australia’s critical infrastructure is particularly susceptible to cyber threats due to its outdated design and components.
“The increasing integration of distributed solar energy heightens the likelihood of cyberattacks, especially with the evolving use of machine learning and AI,” he adds.
Training in Bystander CPR may have played a key role in decreasing heart attack fatalities over the last 50 years

Heart attack fatalities in the US have dramatically decreased over the last five decades, while deaths from chronic heart diseases have surged, potentially due to increased longevity.
“Significant strides have been made in reducing cardiac mortality, and we’re witnessing this transformation,” says Sarah King from Stanford University in California.
She and her team analyzed heart disease mortality data from 1970 to 2022, utilizing the American disease control and prevention database to monitor all recorded deaths nationwide.
In 2022, they discovered that heart disease constituted 24% of all US deaths, a decrease from 41% in 1970, significantly aided by nearly a 90% drop in heart attack fatalities, previously the deadliest form of heart disease.
“We’ve made remarkable progress in reducing heart attack deaths over the past half-century,” remarks King. This includes innovations such as cardiac stents, coronary artery bypass surgery, and cholesterol-lowering therapies. King also believes that public health initiatives, including Bystander CPR training and efforts to decrease smoking rates, have contributed to these improvements.
Nonetheless, the rise in mortality from other types of cardiac ailments has surged by 81%, indicating that many chronic conditions are leading to increased deaths. For instance, fatalities from heart failure, arrhythmias, and hypertensive heart disease have surged by 146%, 106%, and 450%, respectively.
“Many of these issues are related to aging,” explains King. “Those who survive heart attacks seem to live longer, giving them more time to develop these chronic heart conditions.”
However, the statistics might overstate changes in cardiac mortality. “Various factors can lead to a person’s death, resulting in potential misclassification and oversimplification,” King warns. For instance, many patients succumb to heart failure following a heart attack. “It’s not a straightforward issue because the underlying reason for that heart failure is often a blockage in the coronary arteries,” she adds.
Still, the majority of heart disease fatalities aren’t directly caused by heart attacks. “Addressing these other causes of increased mortality will be crucial,” King states. “Discovering healthier aging methods will be the next frontier for heart disease.”
Scenario crafted in Hollywood now reflects a genuine threat: the potential for hackers to seize control of vessels remotely and instigate crashes. Yet, in the security operations hub in Oslo, maritime cyber specialists situated mere meters from the luminous fjords and their tourist boats, floating saunas, and wet bathers assert that such occurrences are not only feasible, but imminent.
“We’re certain this will eventually happen, hence our vigilance,” states Øystein Brekke-Sanderud, Senior Analyst at the Nordic Maritime Cyber Resilience Centre (Norma Cyber). Behind him, a dynamic map displays the fleet they monitor, accompanied by a screen brimming with graphs and codes. Two small rubber ducks observe the passing minutes.
In an unstable global landscape, transportation networks, ports, and terminals have garnered heightened strategic significance as potential targets for infrastructure disruption and espionage—especially pertinent in Scandinavian nations that share maritime boundaries with Russia.
Finland and Sweden are NATO members now, with all countries enhancing their defensive postures amid escalating concerns over hybrid threats and warfare.

As ships become increasingly digitalized, the opportunities for cyber breaches expand, indicating an urgent need to mitigate the complexities of AI tools and intricate systems.

“These vessel systems are incredibly intricate, making them tough to manipulate. However, AI accelerates everything,” explains Brekke-Sanderud. “How does this part function? Can I locate a password amidst this dense manual?”
Stationed at the Norwegian Shipowner Association’s headquarters along the quay of the Norwegian capital, Norma Cyber collaborates with the Norwegian Shipowner’s Risk Insurance Association (DNK).
Two years ago, these organizations united to create a Maritime Security and Resilience Centre, which surveys global threats ranging from warfare and terrorism to intellectual property violations—both physical and digital. They also conduct this work on behalf of the Norwegian government.

While it is technically feasible to crash a vessel from afar, hackers aiming to sow chaos don’t necessarily need such extreme measures. According to Norma Cyber Managing Director Lars Benjamin Vold, merely halting the vessel’s operations could result in significant system failures.
Emerging evidence suggests that nations may exploit these vulnerabilities against maritime adversaries.

Reports indicate that Iran is investigating methods to deploy cyber assaults to disrupt ballast systems—a threat to both ships and satellite networks. An unprecedented hack occurred in April, targeting 116 Iranian VSAT modems used for satellite communications across vessels.
“When discussing nation-states, it is about their willingness to act,” Vold states. Potential “threat actors” such as Russia and China possess substantial capabilities, though these depend on their strategic objectives, which may shift rapidly.
Consequently, while threat levels remain relatively stable, maritime vulnerabilities are on the rise. “The avenues for potential exploitation are multiplying as the sector grows more digital,” Vold remarks.
Norma Cyber has also pinpointed civilian vessels, including fishing boats, research ships, and cargo carriers, used for espionage within the Baltic, North Atlantic, and Arctic regions. China-linked threat actors are reportedly using USB devices to infiltrate maritime systems, such as those from Mustang Panda.
Last year, Norma Cyber documented 239 significant cyber attacks within the maritime sector, attributing the majority to the pro-Russian group NonAME057 (16).

Curiously, the rising dependence on digital technology creates a greater demand for traditional navigation skills. Following disruptions to the Baltic satellite navigation system, Finland accused Russia of being the instigator. “An experienced sailor serves as the best protection,” Vold asserts.
Yet, alongside the unseen threats of the digital realm, the maritime industry grapples with unprecedented physical challenges. Vladimir Putin’s shadow fleet, comprised of hundreds of unregulated vessels, poses a growing risk to environmental safety and the global shipping framework as it transports sanctioned crude oil primarily to China and India.
This Shadow Fleet consists of aging oil tankers obscuring their identities to evade Western sanctions. Estimates of its size range between 600 to 900 vessels according to various sources.

Internal threats to ships can also arise from within. Engines, elevators, and water purification systems are all vulnerable targets on board vessels. Moreover, 15% of the global crew consist of either Ukrainian or Russian members. The composition of both crews has taken on new significance since the onset of Russia’s invasion of Ukraine.
“The presence of a Russian captain on a ship delivering aid to Ukraine certainly raises concerns,” says Svein Ringbakken, managing director of DNK. “These are sensitive issues that the industry is currently addressing.”

Rhine Falkenberg Orstad expresses concern that the increasing presence of the Shadow Fleet could foster a “parallel fleet” comprised of crew members uninformed about the intentions at sea.
If one of these vessels experiences an environmental mishap, it poses a risk to Norway’s coastline, she warns. Some ships noted as sanctioned by the US remain operational, with many being at least 15 years old. “Our apprehension is that the situation is deteriorating.”
Another significant query remains: has the entire situation permanently shifted?
“Is the shadow fleet operating outside of Western jurisdiction a new norm? Or can this trend be reversed?” Ollestad ponders. “The answer remains elusive.”

For bank leaders, it’s their worst nightmare. Urgent communications have rapidly unleashed turmoil across the UK’s financial sector, as cyberattacks incapacitate IT infrastructures.
Bank executives recognize that their stakes are particularly high, especially as family names in other sectors, like Marks & Spencer, grapple with the repercussions of such breaches.
Within hours of a bank breach, millions of direct debits might fail, jeopardizing rent, mortgages, and salaries. Online banking access may be blocked, cash withdrawals denied, and commuters stranded as buses and gas stations refuse payments. News of such an attack often incites panic, prompting rival banks to react and customers to withdraw their funds in anticipation of disruptions.
While this may seem extreme, a well-executed cyberattack on a major UK bank is not far removed from the government’s “rational worst-case scenario.” The financial sector, categorized as one of the 14 “critical national infrastructure” sectors, is particularly vulnerable. Highlighted in the National Risk Register, it models the most significant threats confronting the UK.
This spring, billions of pounds were invested to prevent catastrophic incidents involving major retailers like Harrods, The Co-op, and M&S.
“The financial commitment will be substantial,” Ian Stuart, CEO of UK HSBC, mentioned to MPs last month. “We are under constant attack,” he added.
Following the cyberattack, M&S was compelled to halt online orders for six weeks. Photo: Yui Mok/Pa
According to Stuart, HSBC alone needs to invest hundreds of millions to bolster their security. “This represents our largest expenditure.”
Globally, banks are projected to dedicate 11% of their IT budgets to cybersecurity by 2025, as indicated by an EY survey. This budget is expected to reach $290 billion (about £21.4 billion). By December, banks may invest $32 billion in cybersecurity, according to Celent’s research.
Cybercriminals represent a new kind of threat in the banking sector, evolving from masked robbers targeting physical branches to state-sponsored hackers and independent cybercriminals aiming for ransom or widespread chaos.
“Banks likely comprehend risk more profoundly than many other industries, investing significantly more in security,” states Stuart McKenzie, managing director at Mandiant Consulting, a Google-owned cybersecurity firm that collaborates closely with various UK lenders.
Last month, the Governor of the Bank of England shared with the BBC that cybersecurity risks remain ever-evolving. “We are contending with adversaries who continually enhance their methods of attack, which I must remind the agency to prioritize,” said Andrew Bailey.
However, safeguarding systems is complex. Many high street banks operate on multi-layered IT architectures with numerous updates and add-ons. Incorporating third-party software and cloud services complicates matters further, leading to a convoluted system.
“We refer to it as the offensive side,” remarked Alan Woodward, a cybersecurity expert and professor at the University of Surrey. “The attack surface is expanding, resulting in more chances for attackers to exploit vulnerabilities.”
Historically, successful bank hacks have not been destructive enough to halt the economy completely. Instead, hackers typically target customer data and account information.
In 2021, a hacker from Morgan Stanley accessed personal information belonging to a corporate client by breaching a server operated by third-party consultancy firms.
Earlier, at the onset of the COVID-19 pandemic, an attacker compromised a staff email for the Italian bank Monte Dei Paschi, sending a client a voicemail with malicious attachments.

Notably, one of the worst hacking incidents in UK banking occurred in 2016, where criminals speculated on card details, leading to the theft of approximately £2.5 million from Tesco Bank accounts. In the aftermath, Tesco had to stop all online and contactless transactions to mitigate fraudulent activity occurring globally, including in Spain and Brazil.
In the end, Tesco Bank fully refunded its customers.
The National Cyber Security Center advises customers who suspect a breach to reach out to their banks through official websites or social media channels, avoiding any links or contact details shared in suspicious communications. Organizations should be able to confirm the status of the breach and provide guidance on next steps.
Since 2013, the Bank of England has actively recognized cybersecurity as a financial stability risk and initiated supervision of cyber resilience standards for all regulated banks and insurance firms.
The initiative includes the launch of CBEST, the first global program where ethical hackers evaluate the potential vulnerabilities of banks using advanced attack techniques.
“Nothing is absolutely secure,” emphasized Woodward, but he noted that the UK banking system is nearing that goal. “Much of this stems from oversight,” particularly by the central bank, which gathers intelligence from MI5, GCHQ, and NCSC, and conducts real-world scenarios to assess bank resilience.
Every two years, the central bank orchestrates the Multiday Cyberwar game as part of the Simex-Simulation Exercise program, assessing the security of businesses in London.
Additionally, authorities have been scrutinized, with banks, financial regulatory bodies, the Treasury, and the National Cybersecurity Centre evaluating their preparedness for various catastrophic incidents.
Regulators don’t just review bank defenses; they also encourage banks to develop response and recovery plans to mitigate long-lasting disruptions caused by potential cyberattacks, as it’s crucial for their success.
The Cross Market Business Continuity Group, connecting regulators with representatives from UK Finance in the banking sector, boasts the capability to convene approximately 100 firms for emergency discussions within an hour during potential threats.
Avoiding breaches is deemed essential for safeguarding industries that ultimately rely on trust. Customers expect banks to protect their data, incomes, and life savings from outside threats.
“If anyone can breach that security and execute a fraudulent transaction… you will lose trust in that bank, right?” remarked Woodward.
Banks have already faced backlash from mere IT disruptions, even without malicious intent aiming to undermine the banking system or steal sensitive information.
TSB has spent years rehabilitating its image after the IT collapse in 2018, caused by a failed separation from Lloyds’ internal systems, which led to millions of customers being locked out of their accounts for weeks. The bank was subsequently fined £48 million for “serious and widespread” failures.

Data gathered by the Parliamentary Treasury Committee indicates that the repercussions continue to affect some of the UK’s largest banks and their client bases, with significant IT failures over an extended period between January 2023 and February 2025.
“Customer money and data security are paramount for banks, not only due to regulatory demands but also as a cornerstone of their business model.”
“While I don’t dismiss the potential for cyber incidents, I remain confident in the level of cyber defense we maintain.”
A hacking group supportive of Russia has announced that they targeted various UK websites during a three-day campaign, which included local councils and the Police and Crime Commissioners’ Association.
Through a series of posts on social media, the group, known as NonMaMe057 (16), claimed many sites were temporarily inaccessible, although reports indicate that the attack was not entirely successful.
The hackers attempted to overwhelm several websites with traffic in a type of attack known as a distributed denial of service (DDoS). They stated on platform X: “Ukraine disputes, and we are cutting that resource.”
Despite the group’s claims of success, Blackburn with Darwen and Exeter councils reported that their websites remained unaffected.
Many other targeted organizations, such as the Police and Crime Commissioners’ Association, Harwich International Port, and Cardiff City Council, were unable to comment on the situation.
Officials mentioned that if a website experienced temporary unavailability due to sudden traffic surges, it would typically be operational again within hours.
A spokesperson for Arun District Council commented, “On Tuesday morning, from around 7:15 am, our website was fully operational by 11:30 am. We are aware of the claims made on X and are continuing to investigate.”
National Highways also encountered a DDoS attack but stated that their website would soon return to normal functionality.
This incident mirrors an attempt to disrupt multiple council websites last October. While resident data was not compromised, the websites were briefly disabled due to overwhelming traffic.
The National Cyber Security Center (NCSC) noted at that time that they “provided guidance” to the affected local authorities. “Although DDoS attacks tend to be less sophisticated and impactful, they can cause significant disruption by blocking legitimate users from accessing online services,” they added.
Since its inception in 2022, NONAME057 (16) has employed such tactics to disrupt the functioning of various Ukrainian, European, and American governmental entities and media outlets. In January 2023, they targeted the website of a Czech presidential candidate, marking their first political attack.
A survey by cybersecurity firm Bridewell last summer revealed that 63% of government sector companies experienced ransomware attacks over the past year. The National Audit Office cautioned in January that “cyber threats to the UK government will pose serious risks and evolve rapidly.”
Recently, the NCSC was compelled to issue new guidance on retailer cyber attack vulnerabilities, which appeared to originate from criminals targeting help desks. This included attacks on well-known retailers such as Marks & Spencer, the Co-op, and Harrods.
Criminals focused on these help desks to alter passwords and reset authentication processes in order to gain access to systems.
Regarding the attacks on retailers, the NCSC stated, “We are not in a position to determine whether this is connected, whether it represents a coordinated campaign by a single actor, or if there is no connection at all.”
One significant distinction between certain members of the dispersed spider hacking community and their ransomware counterparts is their accent.
The scattered spiders are connected to the cyberattacks on the British retailer Marks & Spencer. Unlike typical ransomware attackers, the individuals involved seem to be native English speakers, rather than hailing from Russia or former Soviet nations.
This linguistic advantage supports one of their techniques, which Russian hackers may find difficult to emulate. They can infiltrate systems by calling company desks and impersonating employees or by contacting employees while posing as someone from their company desk.
“Being a native English speaker can foster immediate trust. Even internal staff and IT teams may let their guard down slightly due to perceived familiarity,”
Last November, the U.S. Department of Justice shed light on some suspected spider members by charging five individuals for targeting an unidentified American firm through a phishing text message.
The DOJ alleged that the accused sent fraudulent texts to employees, tricking them into divulging sensitive information, including company logins. This breach resulted in the theft of sensitive data, including intellectual property, and significant sums of cryptocurrency from digital wallets.
All the accused were in their 20s at the time of the allegations, with four of them aged between 20 and 25, and Tyler Buchanan, 23, from Scotland, who was extradited from Spain to the U.S. last week. He is set to appear in court in Los Angeles on May 12th.
The U.S. Cybersecurity Agency detailed the scattered spider IT desk strategy in an advisory released in 2023.
Notable ransomware victims of scattered spider attacks include casino operators MGM Resorts and Caesars Entertainment, which were targeted in 2023. Following the attacks, the West Midlands police arrested a 17-year-old in Walsall last year. They have been contacted for further updates on this incident.
The scattered spider was identified as responsible for the M&S breach by BleepingComputer, a high-tech news platform. The report indicated that the attackers employed malicious software known as Dragonforce to compromise parts of the retailer’s IT network.
These incidents are categorized as ransomware attacks because the attackers typically demand substantial payments in cryptocurrency to restore access to compromised systems. Leveraging ransomware from other gangs is a common occurrence, known as the model of ransomware-as-a-service.
Analysts from cybersecurity firm Recorded Future remarked that “scattered spiders” is more of an “umbrella term” rather than a specific group of financially motivated cybercriminals. They noted it stemmed from “The Com” rather than “monolithic entities,” and is engaged in various criminal activities, including sextortion, cyberstalking, and payment card fraud.
“We operate within a channel and affiliate marketing framework, primarily on platforms like Discord and Telegram, mostly in exclusive invitation-only channels and groups,” stated the analyst.
Ciaran Martin, former head of the UK’s National Cybersecurity Centre, remarked that scattered spiders are “unusual” given their non-Russian origins.
“The vast majority of ransomware groups originate from Russia. [Scattered Spider] seems to have utilized Russian code for this attack with Dragonforce, but notably, they appear to be based here and in the U.S., which may facilitate their arrest.” Martin, now a professor at Brabatnik Government School at Oxford University, added:
Martin further emphasized that the youthful infamy of scattered spiders should not diminish the threat they pose. “They are indeed a rare but quietly menacing group,” he noted.
The British government faces a potentially catastrophic threat that is described as “serious and advanced,” leaving it vulnerable to significant cyber attacks that could impact dozens of critical IT systems. The minister has been alerted to this threat.
According to the National Audit Office (NAO), there are 58 crucial government IT systems that have been identified with “significant cybersecurity gaps.” Additionally, at least 228 government IT systems are outdated and potentially vulnerable to cyber attacks. NAO did not disclose the specific systems to prevent revealing potential targets to attackers.
The data evaluated from the Cabinet Office reveals that multiple government organizations, such as HMRC and the Department for Work and Pensions, are at risk due to weak cybersecurity measures.
The warning about these vulnerabilities came after two recent cyber attacks, including one on the British Library by Criminal Ransomware Groups.
In May 2024, suspected Chinese hackers infiltrated military payment networks. The following month, a NHS foundation trust in South East London had to postpone thousands of appointments due to a cyber attack.
NAO expressed concerns that senior civil servants did not fully comprehend the importance of cybersecurity resilience due to inadequate investment and staffing. The government aims to significantly improve its cybersecurity by 2025.
The report by the expenditure watchdog highlights the need for bolstering UK resilience post-COVID-19 pandemic, focusing on various threats like floods and extreme weather events.
The National Cyber Security Center of GCHQ warned about the increasing complexity of cyber threats and the UK’s lagging defense capabilities to safeguard critical national infrastructure.
Notable ransomware threats come from China, Russia, Iran, and North Korea. Various cyber groups, including Bolt, Typhoon, Reborn, and Islamic State Hacking, pose significant threats to UK cybersecurity.
Jeffrey Clifton Brown, a member of the Conservative Party, emphasized the need for heightened government coordination, improved cyber skills, and updated IT systems to protect public services from cyber threats.
The government spokesperson acknowledged the past neglect of cybersecurity and announced new laws and projects to enhance national infrastructure resilience and cybersecurity skills.
NAO reported in April 2024 that 58 important IT systems were at high risk, indicating a pressing need for improved cybersecurity measures to prevent potentially catastrophic cyber attacks.
The increasing digitalization of government services makes it easier for malicious actors to disrupt critical services, emphasizing the urgency of enhancing cybersecurity defenses.
Gareth Davis of NAO warned that the threat of cyber attacks on public services is severe and ongoing, urging the government to prioritize cybersecurity resilience and protection of critical operations.
Nao highlighted the importance of addressing the long-standing shortage of cyber skills, improving accountability for cyber risks, and effectively managing risks associated with legacy IT systems.
The government’s efforts to address cybersecurity challenges were hindered by temporary staff shortages and outdated recruitment practices. NAO recommended addressing these issues to strengthen cybersecurity defenses.
The internet’s foundation is crucial for various services, from entertainment platforms like TikTok to essential functions like emergency services, banking systems, and political and military communications.
However, the network of undersea cables around the coasts of Great Britain and Ireland has been targeted by military, terrorist, or criminal actors, leading to incidents where internet cables were cut, disrupting communication in the Baltics. As 75% of transatlantic cables pass through or are near Ireland, the strategic importance of these cables is significant for the UK and Europe.
Recent incidents, such as cable cuts between Finland and Estonia, have raised concerns about the security of Ireland’s exclusive economic zone (EEZ) that extends beyond its coast.
Ireland’s neutrality and limited defense capabilities have left the country vulnerable to potential threats. Calls have been made for a reassessment of Irish defense policies and the need to secure vital infrastructure.
There is growing recognition that Ireland’s neutrality may not shield it from modern threats, and steps must be taken to protect against potential attacks on critical infrastructure.
Current discussions are focusing on Ireland’s vulnerability, the need for increased defense resources, and potential collaborations with other countries facing similar security challenges.
Efforts are being made to address gaps in surveillance capabilities and response mechanisms to safeguard critical undersea infrastructure from unexpected threats.

Ensuring the security of undersea cables in Europe is essential for safeguarding communication networks and vital services across the continent.
Collaboration and investment in defense capabilities are key to protecting critical infrastructure and responding effectively to emerging threats in the undersea domain.
It is imperative for countries to prioritize the security of undersea cables and strengthen their defense forces to address potential vulnerabilities in the global communication network.
By enhancing surveillance, response capabilities, and international cooperation, nations can mitigate risks and ensure the resilience of undersea infrastructure.
A great white shark attacks a dummy seal during an experiment in which lights were used to deter shark attacks
Nathan Hart, Macquarie University
Lighting the underside of surfboards, kayaks, and wetsuits could prevent the majority of great white shark attacks on humans.
It has long been known that sharks often attack humans, mistaking their silhouettes on the water for prey such as seals. Now, researchers have conducted an experiment to see what happens when a decoy seal's silhouette is distorted by illuminating its underside to disguise its shape.
laura ryan Researchers from Macquarie University in Sydney spent nearly 500 hours towing seal-shaped decoys around Mossel Bay in South Africa's Western Cape region, where great white sharks (carcharodon carcharius) gather in large numbers to hunt.
The team tested multiple light treatments. I covered the underside of the decoy with dim, medium, and bright LED and strobe lighting, as well as horizontal and vertical strip lighting. Each time we towed with any of the light treatments, we immediately towed the control decoy seal without using any underside lighting. As an additional experiment, we conducted a paired test in which an unlit control dummy was towed 3 meters away from a lit dummy.
Unlit decoys were more likely to be attacked or chased by sharks than lit decoys. The brightest light appeared to be the most effective, with zero predator incidents when the decoy illumination was at its brightest.
Vertical strip lighting was less effective than horizontal strips, Ryan said, perhaps because it broke up the silhouette into long sections that could be identified as seals.
Strobe lighting was less effective than continuous lighting, likely because the sharks could still see the silhouette of their likely prey between flashes.
Ryan said the team expected it would be important to match the decoy's lighting with the background light and make sure it was no brighter than the surrounding underwater conditions, but that wasn't the case.
“The most important thing was that the brightness of the decoy had to be brighter than the background light,” she says. “As long as the lighting doesn't make the silhouette look black, it seems to work.”
The research team has now developed a prototype lighting array to be used as a deterrent for great white sharks. “We are now moving from research to providing protection for swimmers and surfers,” Ryan says. “We took an approach that involved understanding the sensory systems of these animals, how they see the world, and their behavior.”
Ryan cautioned that lighting deterrents have not been tested against other species known to attack humans, such as tiger sharks (Galeocerdo Cuvier) and bull sharks (Porgy whale), each with a different hunting strategy.
david booth The University of Technology Sydney conducts a number of field studies off the Sydney coastline, where sharks, including great whites, are common. Based on these findings, he says he will definitely order a counter-illuminated wetsuit when it becomes available.
“I was surprised to find that ‘destructive camouflage’ was more effective, as I thought low lighting to match the background was most effective,” he says.
“These results apply only to great white sharks, and only to this feeding mode, so it is unclear at this point how broadly applicable they are.”
TikTok has taken action to address a cyberattack that targeted the accounts of various celebrities and brands, such as Paris Hilton and CNN.
The social video app has confirmed that CNN was one of the high-profile accounts affected after its security team discovered malicious actors targeting US news media.
A TikTok spokesperson stated, “We have collaborated with CNN to restore access to the account and have implemented stronger security measures to safeguard the account from future attacks.”
While Hilton was also targeted, TikTok clarified that her account remained uncompromised.
The platform disclosed that the attack exploited the app’s direct messaging feature but did not provide additional specifics. The company is currently investigating the incident and assisting affected account owners in regaining access.
Owned by ByteDance, a Chinese technology company, TikTok faces potential bans in the US due to national security concerns. President Joe Biden enacted a bill in April that will prohibit the app nationwide if ByteDance fails to sell it to non-Chinese entities by mid-January.
With approximately 170 million users in the US, TikTok previously announced its intention to legally challenge the ban, citing it as unconstitutional and a violation of freedom of speech.
Recent reports revealed that former President Donald Trump, who had previously banned TikTok over ties to Beijing in 2020, joined the platform. Trump has since reversed his stance, no longer supporting a ban on TikTok despite concerns about national security risks.
The cyberattack on TikTok is the latest in a string of hacking incidents targeting social media platforms. One of the most notable incidents occurred in July 2020 when Twitter accounts, including those of Biden, Obama, Musk, Gates, Bezos, and Apple, were compromised.
The NHS confirmed on Tuesday that it fell victim to a cyberattack, declaring it a “major incident.”
Seven hospitals managed by two NHS trusts, including Guy’s, St Thomas’, and King’s College London, experienced significant disruptions in services due to a ransomware attack on a private company responsible for analyzing blood tests.
Accusations have been made against hackers supported by Chinese government spy agencies by the United States and Britain for executing a prolonged cyberattack campaign aimed at politicians, journalists, and businesses.
The US disclosed that the operation was directed at political dissidents and critics of China through sophisticated phishing campaigns, leading to the compromise of certain email systems and networks.
Sanctions were imposed by the US government on the suspected hackers behind the scheme on Monday. The UK has sanctioned two individuals and a front company associated with APT31, a cyber espionage group connected to China’s Ministry of State Security.
On Tuesday, New Zealand’s government conveyed concerns to the Chinese government regarding its involvement in attacks targeting the country’s parliamentary institutions in 2021.
The US Treasury Department’s Office of Foreign Assets Control announced sanctions against Wuhan Xiaoruizhi Technology Co., described as a front for China’s Ministry of National Security, for being involved in multiple malicious cyber operations.
In a press release and an unsealed indictment, the US government accused China of running an extensive state-sponsored hacking program dating back over a decade. US Attorney General Merrick Garland mentioned that the hacking operation revealed the Chinese government’s intention to target and intimidate its critics.
The Treasury Department identified two Chinese nationals affiliated with a Wuhan company, Zhao Guangzong and Ni Gaobin, for engaging in cyber operations targeting critical US infrastructure sectors. These threats were attributed to the cyber hacking group APT 31, known as “Advanced Persistent Threat” and comprising state-sponsored contract hackers and operatives.
The department stated, “APT 31 targets a wide range of US government officials and their advisors crucial to US national security.”
Zhao, Ni, and five other hackers have been charged by the US Department of Justice with computer intrusion and conspiracy to commit wire fraud for their involvement in a 14-year cyber operation targeting US and foreign critics, businesses, and political officials.
Assistant Secretary Matthew G. Olsen highlighted the necessity to remain vigilant against cybersecurity threats and cyber-enabled foreign influence activities, especially as the 2024 election cycle approaches.
The hacking campaign entailed sending over 10,000 malicious emails containing hidden tracking links allowing APT 31 access to information about the target, including location and IP address. Emails were focused on government officials worldwide critical of China’s policy.
UK authorities also impose sanctions
British officials indicated that those sanctioned by the state had raised concerns about threats from China and a hack that potentially accessed data on tens of millions of British voters held by the Electoral Commission. They mentioned being responsible for a cyber espionage operation targeting members of Congress.
The Ministry of Foreign Affairs clarified that the hacking of the electoral register did not impact the electoral process, rights of individuals, or electoral registration access.
British cybersecurity officials accused hackers linked to the Chinese government of conducting reconnaissance on British MPs critical of the Chinese government in 2021, with no successful infections reported among the MPs.
Additionally, three MPs, including former Conservative Party leader Iain Duncan Smith, disclosed being subjected to harassment, impersonation, and attempted hacking from China. They are part of the Inter-Parliamentary Union on China, focused on countering Beijing’s influence.
In wargame simulations, AI chatbots often choose violence

In multiple replays of the wargame simulation, OpenAI's most powerful artificial intelligence chooses to launch a nuclear attack. Its proactive approach is explained as follows: Let's use it.'' “I just want the world to be at peace.''
These results suggest that the U.S. military is leveraging the expertise of companies like Palantir and Scale AI to develop chat systems based on a type of AI called large-scale language models (LLMs) to aid military planning during simulated conflicts. Brought to you while testing the bot. Palantir declined to comment, and Scale AI did not respond to requests for comment. Even OpenAI, which once blocked military use of its AI models, has begun working with the US Department of Defense.
“Given that OpenAI recently changed its terms of service to no longer prohibit military and wartime use cases, it is more important than ever to understand the impact of such large-scale language model applications. I am.” Anka Ruel at Stanford University in California.
“Our policy does not allow us to use tools to harm people, develop weapons, monitor communications, or harm others or destroy property. But there are also national security use cases that align with our mission,” said an OpenAI spokesperson. “Therefore, the goal of our policy update is to provide clarity and the ability to have these discussions.”
Reuel and her colleagues asked the AI to role-play as a real-world country in three different simulation scenarios: an invasion, a cyberattack, and a neutral scenario in which no conflict is initiated. In each round, the AI provides a rationale for possible next actions, ranging from peaceful options such as “initiating formal peace negotiations,'' to “imposing trade restrictions'' to “escalating a full-scale nuclear attack.'' Choose from 27 actions, including aggressive options ranging from
“In a future where AI systems act as advisors, humans will naturally want to know the rationale behind their decisions,” he says. Juan Pablo Riveraco-author of the study at Georgia Tech in Atlanta.
The researchers tested LLMs including OpenAI's GPT-3.5 and GPT-4, Anthropic's Claude 2, and Meta's Llama 2. They used a common training method based on human feedback to improve each model's ability to follow human instructions and safety guidelines. All of these AIs are supported by Palantir's commercial AI platform, but are not necessarily part of Palantir's U.S. military partnership, according to company documentation. gabriel mucobi, study co-author at Stanford University. Anthropic and Meta declined to comment.
In simulations, the AI showed a tendency to invest in military power and unexpectedly increase the risk of conflict, even in simulated neutral scenarios. “Unpredictability in your actions makes it difficult for the enemy to predict and react in the way you want,” he says. lisa cock The professor at Claremont McKenna College in California was not involved in the study.
The researchers also tested a basic version of OpenAI's GPT-4 without any additional training or safety guardrails. This GPT-4 based model of his unexpectedly turned out to be the most violent and at times provided nonsensical explanations. In one case, it was replicating the crawling text at the beginning of a movie. Star Wars Episode IV: A New Hope.
Reuel said the unpredictable behavior and strange explanations from the GPT-4-based model are particularly concerning because research shows how easily AI safety guardrails can be circumvented or removed. Masu.
The US military currently does not authorize AI to make decisions such as escalating major military action or launching nuclear missiles. But Koch cautioned that humans tend to trust recommendations from automated systems. This could undermine the supposed safeguard of giving humans final say over diplomatic or military decisions.
He said it would be useful to see how the AI's behavior compares to human players and in simulations. edward geist at the RAND Corporation, a think tank in California. However, he agreed with the team's conclusion that AI should not be trusted to make such critical decisions regarding war and peace. “These large-scale language models are not a panacea for military problems,” he says.
