Common Artificial Sweeteners May Disrupt Cancer Treatment

Individuals who consume the artificial sweetener sucralose may have reduced responsiveness to cancer immunotherapy, indicating that sweeteners could diminish treatment efficacy.

Immunotherapy enhances the immune system’s ability to identify and eliminate cancer cells, proving vital for many cancers. “When successful, it is highly effective. Patients can feel better, enjoy their lives, and survive for years,” states Abigail over Eichaldergoff from the University of Pittsburgh, Pennsylvania. “Regrettably, not all patients respond well; many cancer types benefit only a limited number of individuals.”

The reasons behind this are unclear, but numerous studies indicate that the gut microbiota plays a critical role in regulating immune responses; prior research has also demonstrated that artificial sweeteners can modify human gut microorganisms.

Consequently, Overacre and colleagues investigated the potential effects of artificial sweeteners on immunotherapy outcomes. They tracked the treatment results of 157 patients who underwent cancer immunotherapy for a minimum of three months. Among these, 91 had advanced melanoma, 41 had non-advanced non-small cell lung cancer, and 25 had melanoma that had been surgically excised but were at risk of recurrence.

Prior to treatment commencement, participants filled out a dietary questionnaire covering the previous month, enabling researchers to estimate their artificial sweetener intake.

Consumption exceeding 0.16 milligrams of sucralose per kilogram daily correlated with poorer treatment outcomes. Participants with advanced melanoma who ingested lower amounts of sucralose experienced longer survival rates, approximately five months more without cancer progression.

In the case of non-small cell lung cancer participants, the survival advantage was about 11 months. For those at higher risk of melanoma recurrence, reducing sucralose intake allowed them to remain cancer-free an additional six months compared to heavier consumers.

Similar outcomes were noted for participants who consumed more than 0.1 milligrams per kilogram daily of Acesulfame K, another artificial sweetener.

The US Food and Drug Administration (FDA) advises limiting sucralose intake to below 5 milligrams per kilogram daily. “Thus, the threshold which seems to reduce the effectiveness of immunotherapy is not half, or even 25%, but rather about 5% of the recommended daily amount,” states Diwakar Dabar from the University of Pittsburgh. “This suggests that even a small amount could have a detrimental effect.”

Additional experiments with mice bearing various types of tumors demonstrated that adding sucralose to their water during immunotherapy expedited tumor growth and decreased survival rates.

Genetic analysis revealed that immune cells activated by immunotherapy were less effective in mice provided with sucralose to combat cancer. Fecal analyses also indicated significant alterations in the rodent gut microbiota, notably increased activity in the metabolic pathway utilized by T cells to process arginine, a crucial amino acid.

The findings imply that sucralose may hinder immunotherapy by reducing arginine levels and modifying gut microbiota in ways that impair T-cell efficacy. Furthermore, experiments demonstrated that arginine supplementation improved survival rates in mice consuming sucralose, bringing them in line with those not consuming artificial sweeteners.

However, it remains uncertain if sucralose exerts similar effects on human gut microbiota and T-cell function. Josam Suez from Johns Hopkins University in Maryland notes, “It is incredibly challenging to derive findings based solely on human data, particularly regarding nutrition and food frequency surveys, while isolating specific impacts of non-nutritive sweeteners and isolating the effects of sucralose on clinical outcomes.”

“We invest considerable resources in the development of new medications, which is costly, challenging, and time-consuming,” remarks Davar. Discovering ways to enhance existing treatments, such as avoiding artificial sweeteners or using arginine supplements, presents a more straightforward and economical approach.

Nonetheless, further investigation is essential to determine if it genuinely enhances patient outcomes. “Hence, it is crucial to maintain support for these research priorities in a challenging funding landscape,” concludes Davar.

Cyber Attacks Could Target Home Solar Panels to Disrupt Power Grids

A third of Australian homes feature rooftop solar panels

ZSTOCKPHOTOS/ISTOCKPHOTO/GETTY IMAGES

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.

Starlink Satellites Emitting Radio Signals That May Disrupt Astronomy

A new batch of Starlink satellites deployed via Falcon 9 Rocket

SpaceX

Astronomers have raised concerns that SpaceX’s Starlink satellites emit radio waves that may jeopardize their ability to observe and comprehend the early universe.

With thousands of Starlink satellites in orbit offering worldwide internet coverage, astronomers worry that radio emissions from these satellites could interfere with sensitive telescopes monitoring distant and faint radio waves. Although SpaceX has collaborated with astronomers to minimize this disruption by disabling transmission beams while passing over significant telescopes, these measures seem insufficient.

Steven Tingay from Curtin University, Australia, along with his team, is currently tracking signals from nearly 2,000 Starlink satellites using prototype telescopes at the Square Kilometer Array-low Observatory (SKA-low). This future network of over 100,000 interconnected telescopes is designed to investigate the early universe, but researchers have found that Starlink signals could jeopardize their goals by affecting a third of the data gathered at numerous frequencies.

Additionally, they found that the satellites transmit signals in two frequency bands protected for radio astronomy by the International Telecommunications Union (ITU), which should not be utilized for Starlink transmissions. Yet, these satellite emissions are deemed unintentional. The leaked signals are 10,000 times stronger than the faint radio emissions from the neutral hydrogen clouds that existed when the first stars began to form, and which astronomers wish to study to decode the early universe.

“The signal strength from these unintended emissions can rival some of the brightest natural radio sources in the sky,” Tingay explains. “It’s akin to taking the strongest sauces in the sky, adding even more artificial ones, and causing significant interference, especially in experiments that target super sensitivity.”

Tingay suggests that the emissions likely arise from onboard electronics inadvertently transmitting signals through satellite antennas. He notes that while such leaks are not technically illegal, as ITU regulations only cover intentional emissions, the discourse about how to regulate these types of emissions is starting at the ITU, which has withheld comment.

Dylan Grigg, another researcher from Curtin University, emphasizes, “The optimal approach to mitigate these unintended emissions is for satellites to either reduce or eliminate them. From the operator’s perspective, it’s beneficial that there are existing mitigation strategies in satellites, which SpaceX has already implemented for optical astronomy.” Starlink has adjusted its satellites to minimize light reflection to reduce visual interference.

A spokesperson for SKA-LOW remarked, “These findings align with our previous studies, but additional research is necessary to fully grasp the impact on low-frequency observations.”

Grigg and Tingay have shared their findings with SpaceX, stating that the company is open to discussions on strategies to decrease emissions. SpaceX has not commented on the matter.

If SpaceX cannot devise a solution, researchers may need to introduce algorithmic strategies to filter out contaminated radio waves. However, Tingay pointed out that such methods are still in their early development phases and might require more computational resources than are currently needed for basic processing of the astronomical signals of interest.

Microsoft Employees Disrupt CEO’s Keynote in Protest Against Pro-Palestinian Technology

Employees at Microsoft disrupted a keynote speech by the CEO during a pro-Palestinian protest at the company’s annual developer conference on Monday.

Microsoft firmware engineer Joe Lopez, involved in the development of the Azure cloud computing platform, was confronted by security shortly after he challenged Satya Nadella.

“Satya, are you aware that Microsoft is contributing to the deaths of Palestinians?” Lopez exclaimed. “Why not highlight how Israeli war crimes are facilitated by the cloud?”




Pro-Palestinian protesters disrupt Microsoft Keynote speech – video

Following the incident, Lopez sent out a company-wide email detailing his reasons for protesting.

“As a major global corporation, Microsoft holds significant power to effect positive change. We must either end this ongoing tragedy or cease our technical support for Israel,” the email stated. This statement is also available on Medium. “Should our leadership continue to dismiss this demand, it won’t go unnoticed. The world is waking up to our complicity and is voicing its opposition. Boycotts will escalate, and our reputation will suffer immensely.”

Organizers from a worker-led group named No Azure for Apartheid (NOAA) coordinated protests that coincided with the developer conference. This group has been actively protesting Microsoft’s cloud computing agreements with the Israeli military for over a year, asserting that Azure Cloud services have facilitated the surveillance of Palestinian citizens as well as Israeli military operations. An Ofek Unit manages a database of potential airstrike targets. Leaked documents reportedly reveal that Microsoft has “significant footprints across major military infrastructure” in Israel, according to +972 Magazine.

“The initiative began over a year ago. No Azure for Apartheid campaigns launched in response to the humanitarian crisis unfolding over the past seven months,” noted Anna Hattle, a Microsoft employee and NOAA organizer, in an email to the management on May 15th. Crimes from 77 years ago highlight the critical difference today, where Israeli forces are executing genocidal acts on a much larger scale, aided by Microsoft’s Cloud and AI technologies.”

Lopez’s protest is the second such incident within two months. On April 6, Microsoft employees Ibtihal Aboussad and Vaniya Agrawal interrupted an AI event, accusing the company’s AI head, Mustafa Suleyman, of war profiteering. Both employees were subsequently terminated. The current status of Lopez’s job is still unclear. Last year, Google experienced similar internal protests regarding its contracts with the Israeli military.

In response to concerns about Microsoft’s technology being utilized by the Israeli military, Microsoft stated that investigations found no evidence showing that their technology was used to endanger or target civilians. However, the activist group NOAA has disputed this conclusion. Microsoft has yet to issue a comment regarding Lopez’s protest.

“Leadership dismisses our assertion that Azure technology is being employed to target or harm civilians in Gaza. Those of us who are aware understand that this is a blatant falsehood,” Lopez emphasized in his email to staff. “We don’t need internal audits to recognize that key Azure clients are engaged in human rights violations. This reality becomes evident online each day.”

Lopez’s protest coincides with the remembrance of the Nakba, marking 77 years since the event.

Solar Storms Disrupt Communication and Power Systems

The sun has unleashed its power with two significant flares occurring early Wednesday, just a day after NASA’s Observatory captured a stunning image of another solar flare.

These consecutive eruptions are among the strongest recorded, reportedly causing shortwave radio blackouts across at least five continents. This week’s explosive activity may signal an increase in solar activity.

The Sun Storm reached its peak around 4:25 AM ET on Wednesday, when a massive X-class flare ejected plasma streams and charged particles into space.

“Flares of this magnitude are uncommon,” stated an official from the National Oceanic and Atmospheric Administration’s Space Weather Prediction Center. I included this information in the event summary.

Solar flares are categorized into five classes based on their intensity. The smallest flares are A-class storms, followed by B-class, C-class, M-class, and the most potent X-class. Each letter represents a tenfold increase in energy compared to the previous class, as explained by NASA.

In addition to the letter classification, scientists use a scale from 1 to 9 to describe the intensity of solar storms.

During the solar tempest on Wednesday, the Space Weather Prediction Center recorded an X2.7 flare before 4:30 AM and an M5.3 flare just hours earlier.

Another X1.2 flare erupted the previous day around 11:38 AM ET, according to NASA. The Solar Dynamics Observatory, launched in 2010, captured a breathtaking image of this fiery event, showcasing the X-Class flares’ dramatic tendrils.

Intense solar storms pose dangers to astronauts in space and can disrupt GPS systems and satellites. If these storms are directed towards Earth, they send a surge of charged particles that can interfere with radio communications and even the power grid.

Since Tuesday, shortwave radio blackouts have been reported in parts of North America, South America, Southeast Asia, Africa, and the Middle East. According to Spaceweather.com, a website managed by astronomer Tony Phillips, the daily activities of the Sun are closely monitored.

Sean Dahl, a forecaster at NOAA’s Space Weather Prediction Center, noted that the X2.7 flare impacted the Middle East, resulting in disruptions of high-frequency radio signals in the area for about 10 minutes during the storm’s peak.

Aside from the potential for “[high-frequency] Communication Disruptions Due to shortwave fading issues, we are not aware of any other significant effects,” Dahl stated.

However, solar storms can also have more benign consequences for Earth, such as enhanced displays of the Aurora. When charged particles collide with the Earth’s magnetic field and interact with atoms in the upper atmosphere, they can create spectacular auroras at lower latitudes than usual.

Scientists indicated last year that we have entered a busy phase of the sun’s natural 11-year cycle. This period of heightened activity, known as the solar maximum, is expected to continue until this year, suggesting more solar storms may occur in the coming months.

Dahl mentioned that this Wednesday’s flare was the strongest so far, but not the largest in the current solar activity cycle. That title belongs to the Monster Flare – an X9.0 Eruption that occurred on October 3, 2024.

Is AI going to disrupt your favorite TV shows?

Justine Bateman won’t name names, but a TV showrunner friend once came to her with a dilemma: Their team was well into shooting the second season of their show, and a network executive had an idea: A character in the pilot wasn’t going over well with viewers, so they wanted to replace him with a different character, using a bit of AI. The showrunner, and actor-director Bateman, were understandably furious. “When you change the beginning of something, you change the creative trajectory,” Bateman says. “It takes away what was set up in the pilot, and it doesn’t make sense, so people are going to be shocked when they see episodes three or four.” Using AI may have seemed like an easy solution for executives, but it was disastrous for the showrunners.

But AI is increasingly becoming a part of the TV industry, with potentially huge costs for the industry. WGA and SAG-Aftra made a big fuss about AI potentially taking jobs during last year’s Hollywood walkouts, but Recent Reports According to CVL Economics, 203,800 entertainment jobs in the US are likely to be “disrupted” by AI by 2026, making the technology a terrifying game changer for television and the entertainment industry as a whole.

While the use of AI is still considered something of a landmine in Hollywood, with most carefully avoiding public skepticism and the (rightful) perception that they’re replacing humans with computers, that doesn’t mean AI is already ubiquitous. “A lot of what people are calling ‘AI’ has been around for the last decade,” says Emily St. James, a TV writer, podcaster, and cultural critic. Disney+ is Speaker He transformed the hoarse voice of Mark Hamill, who was 68 years old at the time, into the voice of 20-year-old Luke Skywalker in The Mandalorian.

The B.B.C. Amazon-MGM Studios has admitted to using AI to create marketing materials (including some bizarrely inaccurate ones) for shows like Doctor Who and Fallout.

“AI doesn’t do quality work, AI just does a good enough job”… Keeping Up With the Kardashians. Photo: Landmark Media/AlamyThat doesn’t mean AI can produce entire shows, though. Not yet. “There’s still a big gap between machine learning simplifying technical processes in ways humans can’t and ‘dominating TV,'” St. James says. “Maybe I’m whistling past my grave, but I haven’t seen anything quite as convincing as the hype yet.”

Others agree, with creative director Lauren Fisher saying, “From what I’ve seen, all the pure ‘let’s have an AI do it all’ stuff is awful, but it’s novelty so I just admire it.” TV producer Benjamin Field adds, “AI can’t make quality stuff, it can only be good enough.” One showrunner quips anonymously, “AI will never replace good stuff, for the same reason that sex robots will never replace the real thing.”

“I think AI can do the mundane work,” says Guy Branum, a writer and producer who has worked on shows like Hacks, The Other Two, and The Mindy Project. “I was once tasked with writing the VMAs bios, which basically consisted of copying old bios and updating them to include current talent. ChatGPT could do that with the right oversight, but all it can really do is steal from existing work and summarize it in the most formulaic way.” But if a show has an established blueprint, like Big Brother, for example, then it’s a lot harder to write. Or for a show like “RuPaul’s Drag Race,” it may not be a question of “if” we’ll get to see AI-generated challenges and scripts, but rather “when.”

It’s more a question of “when” than “if,” but formulaic shows like Ru Paul’s Drag Race could soon be subject to AI material. Photo: Gerard Gethings and Greg BaileyBeing so reflective, most experts say AI probably won’t write great comedy, or at least topical satire like we see in shows like “Last Week Tonight With John Oliver.” Still, there are plenty of TV shows that aren’t sharp or timely, from Netflix dating shows to Hallmark Christmas movies, all of which could conceivably be influenced by AI material. Of course, more channels and streaming services mean more content, and it all has to be written by someone or something.

“In the next six to 12 months, you’re going to see FAST (free ad-supported TV) or social media channels develop AI content,” Field says. “It’s probably going to be made by minimal creators and there’s no real money being spent on it, but it’s going to be out there somewhere. It might do some funny stuff, but it’s not going to change the world. It’s just going to be cheaper and less good.”

But that doesn’t mean creators are grudgingly embracing the technology. Field himself Co-founded the company They’re dedicated to creating “ethical, policy-based” synthetic media. “We’re in a terrible situation where budgets are being cut and AI has the ability to create content cheaper and faster,” Field said. “I don’t necessarily see it as something that’s going to force us into a corner and take away all our jobs, but I do think that as an industry we need to do better and work towards the future in a more sustainable way. Let’s take all the tools that are available to us and use them to create something new.”

Other creators are trying to thwart the rise of AI. Voice Actors Guild of America Nava has taken an active stance against the mistreatment of the group by overzealous executives and producers, and they’re not only working to change the voice-over industry, but lobbying the U.S. Congress for legal protections. Anti-Counterfeiting Law And that AI Fraud Prevention ActBoth are currently in the legislative process.

Amazing deepfakesSome of them used fake voiceovers of President Biden to discourage people from voting in state primaries.

In the entertainment world, these cheap and easy voiceprints have made it much faster to get a busy actor to re-record a few lines, but also allowed companies to create large volumes of dialogue using an actor’s existing work. Veteran BAFTA-winning voice actor Cissy Jones says that a few years ago she found her voice in multiple productions on multiple websites, despite never having contributed to a single project. Fans of her show, The Owl House, were editing videos using her voice, saying lines she never recorded, which “quickly became quite pornographic,” she says.

“This was done without my consent and of course with no control over how it was used and no compensation whatsoever,” Jones said, adding that even though he’s an adult, he would be particularly troubled if such AI creations used the voices of child actors. “You can imagine that this is happening soon.” Jones’ voice was fed into an AI engine, and Jones said he had heard the sound engineer was asked to do so by the client to save money on script changes. They want voice actors to be able to decide whether they want a digital replica of their voice, and whether they have control and compensation every time their voice is used. To this end, the group Etoboxit has its own database of actors’ voiceprints, all of which are available for creators to use.

After newsletter promotionThough fan edits using Jones’ voice aren’t allowed, some are optimistic that AI might create alternate-universe versions of fan-favorite shows. While the idea of studios being able to churn out new episodes of “I Love Lucy” or “The Brady Bunch” may seem odd from an artistic standpoint, some are hopeful that animated series like “The Simpsons” and “South Park” will see the value (and revenue potential) in letting fans make their own “episodes.”

“Maybe you’ll say, ‘Please put me in that episode. I want to be friends with the main character’… You could be on The Simpsons in no time.” Edward Saatchi, CEO Fable Simulationhis company says. Showrunner The company wants to put TV production in the hands of viewers. “Maybe you’re at home and you finish watching a particular season of a TV show,” he said. “You click to watch the next episode and you say, ‘I want to be in that episode. I want to be friends with the main character,’ or, ‘I want it to be roughly like this.’ We want to make it easier for you to tell original stories and make a TV show about your life.”

The showrunners also produce their own original programming, including: Deguchi Valleyis a satirical animated series that “stars” Silicon Valley billionaires. It has already released two episodes and is calling on its 1,000 users (7,500 on a waiting list) to create more. Users can enter prompts of 10-15 words to create full-scale scenes that run from 2 to 16 minutes. A jury of filmmakers and creators will be selected to choose the 20 best episodes, and Saatchi said the episode creators will receive a cash prize and a cut of stream revenue.

“We want to create something that will stand the test of time,” Saatchi said. “It has to be plausible that you’d love to sit down with your friends and watch that episode of Exit Valley. It has to be believable that it’s actually cool, not just because it was made by an AI.”

“Traditional TV is already being disrupted,” says cultural critic and media expert Doug Shapiro. “For years, the argument has been that YouTube isn’t competitive and isn’t professionally producing content. But that 10% doesn’t even reflect mobile or PC viewing; it’s the percentage of people turning on the TV in their living room and watching YouTube. Disruption from below is already happening. The real question now with AI is whether these tools will add fuel to the fire and drive the tens of millions of creators who are already making their own content even further up the quality and performance curve, increasingly competing with Hollywood for people’s time.”

“To use a Game of Thrones analogy, Netflix vs. Disney is like House Targaryen vs. House Lannister, except there’s an army of the dead at the wall: tens of millions of individual creators,” Shapiro added.

As professionally produced content becomes interchangeable with consumer and AI-produced content, this sea change could have far-reaching effects on Hollywood beyond the loss of 200,000 jobs. If DIY AI TV becomes widespread, it could turn the entire concept of television upside down, upending art and fame as we know it. Or, as Saatchi puts it, if AI continues to make its way into TV, “you won’t get your 15 minutes of fame. You’ll get seven seasons and a syndication deal.”

Why cats annoyingly always choose to disrupt your laptop usage

Do you own a precious and adorable cat? If so, your feline friend may be obstructing your view of this page and causing havoc once again, particularly if you are browsing on a laptop.

But why do cats have this tendency? What drives them to interfere with our computers?

Unfortunately, there have not been any extensive scientific studies to explore this question yet. However, cat behavior experts have a relevant theory that could shed light on why cats love to sit on keyboards.



Why does my cat sit on my laptop?

It’s unlikely that your cat wants to mimic your typing or join in with your computer activities. Recent research suggests that cats are capable of imitating human actions, such as touching objects with specific body parts. However, typing is a behavior that cats struggle to replicate, as explained by Dr. David Sands, an Animal Psychology Expert with over 25 years of experience.

While laptops do emit heat which may attract cats, the main draw for felines is the smell of their owners on the keyboard. Cats have a strong sense of smell and enjoy leaving their scent on objects to show ownership. This behavior is more about claiming territory and marking their humans rather than seeking warmth or copying human actions.

In summary, it’s not harmful for your cat to sit on your laptop physically, but if the behavior becomes excessive or is accompanied by other signs of anxiety or attention-seeking, it may be worth monitoring.

Iran-affiliated hackers disrupt UAE TV streaming service by creating fake news using deepfake technology

According to Microsoft analysts, Iranian state-backed hackers disrupted a television streaming service in the United Arab Emirates and broadcast a deepfake newsreader distributing reports on the Gaza war.

Microsoft announced that a hacking operation by the Islamic Revolutionary Guards Corps disrupted streaming platforms in the UAE with an AI-generated news broadcast dubbed “For Humanity.”

The fake news anchors introduced unverified images showing wounded and killed Palestinians in Israeli military operations in Gaza. The hacker group known as Cotton Sandstorm hacked three online streaming services and published a video on the messaging platform Telegram showing them disrupting a news channel with fake newscasters, according to Microsoft analysts.

Dubai residents using HK1RBOXX set-top boxes received a message in December that read, “To get this message to you, we have no choice but to hack you,” the UAE-based news service said. The AI-generated anchor then introduced a message that read: “Graphic” images and captions showing the number of casualties in Gaza so far.

Microsoft also noted reports of disruptions in Canada and the United Kingdom, where channels including the BBC were affected, although the BBC was not directly hacked.

In a blog post, Microsoft said, “This is the first Iranian influence operation where AI plays a key element in messaging, and is an example of the rapid and significant expansion of the Iranian operation’s scope since its inception.”

“The confusion was also felt by viewers in the UAE, UK, and Canada.”

Breakthroughs in generative AI technology have led to an increase in deepfake content online, which has raised concerns about its potential to disrupt elections, including the US presidential election.

Experts are concerned that AI-generated materials could be deployed on a large scale to disrupt elections this year, including the US presidential election. Iran targeted the 2020 US election with a cyber campaign that included sending threatening emails to voters posing as members of the far-right Proud Boys group and launching a website inciting violence against FBI Director Christopher Wray and others. Spreading disinformation about voting infrastructure.

Microsoft said that since the Oct. 7 Hamas attack, Iranian state-backed forces have engaged in a series of cyberattacks and attempts to manipulate public opinion online, including attacks on targets in Israel, Albania, Bahrain (a signatory to the Abraham Accords formalizing relations with Israel), and the US.
