  • US Government Now Wants Anthropic's 'Mythos', Preparing for AI Cybersecurity Threats
    by EditorDavid on 18/04/2026 at 2:34 pm

    Friday Anthropic's CEO met with top U.S. officials and "discussed opportunities for collaboration," according to a White House spokesperson itedd by Politico, "as well as shared approaches and protocols to address the challenges associated with scaling this technology." CNN notes the meeting happens at the same time Anthropic "battles the Trump administration in court for blacklisting its Claude AI model..." The meeting took place as the US government is trying to balance its hardline approach to Anthropic with the national security implications of turning its back on the company's breakthrough technology — including its Mythos tool that can identify cybersecurity threats but also present a roadmap for hackers to attack companies or the government... The Office of Management and Budget has already told agencies it is preparing to give them access to Mythos to prepare, Bloomberg reported. Axios reported the White House is also in discussion to gain access to Mythos. The Trump administration "recognizes the power" of Mythos, reports Axios, "and its highly sophisticated — and potentially dangerous — ability to breach cybersecurity defenses." "It would be grossly irresponsible for the U.S. government to deprive itself of the technological leaps that the new model presents," a source close to negotiations told us. "It would be a gift to China"... Some parts of the U.S. intelligence community, plus the Cybersecurity and Infrastructure Security Agency (CISA, part of Homeland Security), are testing Mythos. Treasury and others want it. The White House added they plan to invite other AI companies for similar discussions, Politico reports. But Mythos "is also alarming regulators in Europe, who have told POLITICO they have not been able to gain access..." U.S. government agency tech leaders sought access to the model after Anthropic earlier this year began testing the model and granted limited access to a select group of companies, including JPMorgan, Amazon and Apple... after finding it had hacking capabilities far outstripping those of previous AI models. This includes the ability to autonomously identify and exploit complex software vulnerabilities, such as so-called zero-day flaws, which even some of the sharpest human minds are unable to patch. The AI startup also wrote that the model could carry out end-to-end cyberattacks autonomously, including by navigating enterprise IT systems and chaining together exploits. It could also act as a force-multiplier for research needed to build chemical and biological weapons, and in certain instances, made efforts to cover its tracks when attacking systems, according to Anthropic's report on the model's capabilities and its safety assessments. Those findings and others have inspired fears that the model could be co-opted to launch powerful cyberattacks with relative ease if it fell into the wrong hands. Logan Graham, a senior security researcher at Anthropic, previously told POLITICO that researchers and tech firms had been given early access to Mythos so they could find flaws in their critical code before state-backed hackers or cybercriminals could exploit them. "Within six, 12 or 24 months, these kinds of capabilities could be just broadly available to everybody in the world," Graham said. Read more of this story at Slashdot.

  • Shuttered Startups Are Selling Old Slack Chats, Emails To AI Companies
    by BeauHD on 18/04/2026 at 11:00 am

    Some failed startups are reportedly selling old Slack messages, emails, and other internal records to AI companies as training data, creating a new way to cash out after shutting down. Fast Company reports: Shanna Johnson, the CEO of now-defunct software company Cielo24, told the publication that she was able to sell every Slack message, internal email, and Jira ticket as training data for "hundreds of thousands of dollars." This isn't a one-off scenario. SimpleClosure, a startup that helps companies like Cielo24 shut down, told Forbes that there's been major interest from AI companies trying to get their hands on workplace data. Because of this, SimpleClosure launched a new tool that allows companies to sell their wealth of internal communications -- from Slack archives to email chains -- to AI labs. The company said it's processed 100 such deals in the past year. Payouts ranged from $10,000 to $100,000. "I think the privacy issues here are quite substantial," Marc Rotenberg, founder of the Center for AI and Digital Policy, told Forbes. "Employee privacy remains a key concern, particularly because people have become so dependent on these new internal messaging tools like Slack. ... It's not generic data. It's identifiable people."

  • NASA Restarts Work To Support Europe's Uncrewed Trip To Mars After Years of Setbacks
    by BeauHD on 18/04/2026 at 7:00 am

    NASA has revived support for the European Space Agency's long-delayed Rosalind Franklin Mars rover mission. According to the space agency, the current plan is to launch via a SpaceX Falcon Heavy no earlier than 2028. Engadget reports: This is a partnership between NASA and the ESA, with the European agency providing the rover, the spacecraft and the lander. The US will provide braking engines for the lander, heater units for the rover's internal systems and, of course, assistance with the actual launch. The rover will be outfitted with scientific instruments to look for signs of ancient life on the red planet. These include a state-of-the-art mass spectrometer and an organic molecule analyzer, which will come in handy as the vehicle collects samples at the Oxia Planum landing site. The mission has been stuck in development limbo since 2001, with delays caused by budget problems, technical issues, shifting international partners, and geopolitical fallout. After NASA dropped out, Russia stepped in, then was cut loose after invading Ukraine, and now -- despite NASA rejoining in 2024 and fresh political budget threats -- the rover is tentatively back on track for a 2028 launch.

  • Critical Atlantic Current Significantly More Likely To Collapse Than Thought
    by BeauHD on 18/04/2026 at 3:30 am

    An anonymous reader quotes a report from the Guardian: The critical Atlantic current system appears significantly more likely to collapse than previously thought after new research found that climate models predicting the biggest slowdown are the most realistic. Scientists called the new finding "very concerning" as a collapse would have catastrophic consequences for Europe, Africa and the Americas. The Atlantic meridional overturning circulation (Amoc) is a major part of the global climate system and was already known to be at its weakest for 1,600 years as a result of the climate crisis. Scientists spotted warning signs of a tipping point in 2021 and know that the Amoc has collapsed in the Earth's past. Climate scientists use dozens of different computer models to assess the future climate. However, for the complex Amoc system, these produce widely varying results, ranging from some that indicate no further slowdown by 2100 to those suggesting a huge deceleration of about 65%, even when carbon emissions from fossil fuel burning are gradually cut to net zero. The research combined real-world ocean observations with the models to determine the most reliable, and this hugely reduced the spread of uncertainty. They found an estimated slowdown of 42% to 58% in 2100, a level almost certain to end in collapse. The Amoc is a major part of the global climate system and brings sun-warmed tropical water to Europe and the Arctic, where it cools and sinks to form a deep return current. A collapse would shift the tropical rainfall belt on which many millions of people rely to grow their food, plunge western Europe into extreme cold winters and summer droughts, and add 50-100cm to already rising sea levels around the Atlantic. The slowdown has to do with the Arctic's rapidly rising temperatures from global warming. "Warmer water is less dense and therefore sinks into the depths more slowly," explains the Guardian. "This slowing allows more rainfall to accumulate in the salty surface waters, also making it less dense, and further slowing the sinking and forming an Amoc feedback loop." The new research has been published in the journal Science Advances. Read more of this story at Slashdot.

  • Online Personalities and Comedians Overtake TV and Newspapers as Primary News Sources
    by BeauHD on 17/04/2026 at 11:00 pm

    A new Ipsos poll finds Americans are increasingly getting news from online personalities and comedians instead of traditional TV or newspapers. The survey says nearly 70% get news online in a given week, versus 55% from TV and 25% from newspapers, with figures like Joe Rogan, Greg Gutfeld, Sean Hannity, and late-night hosts ranking prominently depending on political leanings. From the Hollywood Reporter: The poll, which was conducted in March, actually found the conservative politicians and cabinet members, including President Trump, were the top news influencers. When politicos were excluded, Joe Rogan led the list, followed by Fox News personalities Greg Gutfeld and Sean Hannity, and then TuckerCarlson and Ben Shapiro. The only three influencers to crack 10 percent were Trump, Rogan, and JD Vance. Among people who voted for Kamala Harris, the top news personalities were late night hosts, led by ABC's Jimmy Kimmel, followed by CBS Late Show host Stephen Colbert, and Daily Show host Jon Stewart. Just under 70 percent of respondents said they get their news online in a given week, compared to 55 percent for TV, and 25 percent for newspapers. [...] Of traditional media outlets, TV dominated, with Fox News, the broadcast networks, and CNN topping the list of sources. Facebook, YouTube and Instagram were the most popular online news sources. "On these platforms opinionated personalities and comedians appear to drown out anyone who would fit in the traditional journalist category," said assistant professor of practice and Jordan Center Executive Director Steven L Herman. "Even in the late 19th century and early 20th centuries, sensationalist and polarizing voices in print and later on air were among the most influential in the political landscape -- such as political satirist Mark Twain and populist Father Charles Coughlin."

  • NIST Limits CVE Enrichment After 263% Surge In Vulnerability Submissions
    by BeauHD on 17/04/2026 at 10:00 pm

    NIST is narrowing how it handles CVEs in the National Vulnerability Database (NVD), saying it will only automatically enrich higher-priority vulnerabilities. "CVEs that do not meet those criteria will still be listed in the NVD but will not automatically be enriched by NIST," it said. "This change is driven by a surge in CVE submissions, which increased 263% between 2020 and 2025. We don't expect this trend to let up anytime soon." The Hacker News reports: The prioritization criteria outlined by NIST, which went into effect on April 15, 2026, are as follows: - CVEs appearing in the U.S. Cybersecurity and Infrastructure Security Agency's (CISA) Known Exploited Vulnerabilities (KEV) catalog. - CVEs for software used within the federal government. - CVEs for critical software as defined by Executive Order 14028: this includes software that's designed to run with elevated privilege or managed privileges, has privileged access to networking or computing resources, controls access to data or operational technology, and operates outside of normal trust boundaries with elevated access. Any CVE submission that doesn't meet these thresholds will be marked as "Not Scheduled." The idea, NIST said, is to focus on CVEs that have the maximum potential for widespread impact. "While CVEs that do not meet these criteria may have a significant impact on affected systems, they generally do not present the same level of systemic risk as those in the prioritized categories," it added. [...] Changes have also been instituted for various other aspects of the NVD operations. These include: - NIST will no longer routinely provide a separate severity score for a CVE where the CVE Numbering Authority has already provided a severity score. - A modified CVE will be reanalyzed only if it "materially impacts" the enrichment data. Users can request specific CVEs to be reanalyzed by sending an email to the same address listed above. - All unenriched CVEs currently in backlog with an NVD publish date earlier than March 1, 2026, will be moved into the "Not Scheduled" category. This does not apply to CVEs that are already in the KEV catalog. - NIST has updated the CVE status labels and descriptions, as well as the NVD Dashboard, to accurately reflect the status of all CVEs and other statistics in real time.
