Pentagon deploys Anthropic’s Mythos to patch cyber gaps while planning to ditch firm

Published by Sam Flores

WASHINGTON, May 12 : The Pentagon is deploying Anthropic’s Mythos cybersecurity model to find and patch software vulnerabilities across the U.S. government even as it races to complete a transition away from the AI company, the Defense Department’s top technology official said on Tuesday. Announced on April 7, Mythos is being deployed as part of Anthropic’s “Project Glasswing,” a controlled initiative under which select organizations are permitted to use ​the unreleased Claude Mythos Preview model for defensive cybersecurity purposes. Mythos, according to Anthropic, is capable of detecting decades-old vulnerabilities in web browsers, infrastructure and software. Emil Michael, the Defense Department’s chief technology officer and under secretary for research and engineering, said the Pentagon continues to execute on its plan to remove Anthropic’s products from its work in the coming months. However, he said the Mythos issue “is a national security moment” where the government has hardened up networks, because that model has capabilities that are particular to finding cyber vulnerabilities and patching them. Michael told attendees at a conference in Washington, D.C., that while those …

How Anthropic’s Mythos has rewritten Firefox’s approach to cybersecurity

Published by skeptic

When Anthropic unveiled its new Mythos model in April, it also delivered a stern warning to anyone developing software. The model was so powerful at sniffing out software vulnerabilities, the lab claimed, that it had discovered thousands of high-severity bugs that would need to be fixed before it could be made public. Now, security researchers for Mozilla’s Firefox browser are providing a closer look at what that process has looked like in practice, and what Mythos’ powers mean for software security at large. In a post published on Thursday, Mozilla said Mythos has unearthed a wealth of high-severity bugs, including some that had lain dormant in the code for more than a decade. That’s a significant improvement from what AI security tools were capable of even six months ago. Until now, AI bug-finding tools have come with severe drawbacks, often inundating security teams with low quality reports and false positives. But Mozilla’s researchers say the latest generation of tools have turned a corner, particularly now that agentic systems can assess their own work and filter …

oxygen/Moment via Getty Images Follow ZDNET: Add us as a preferred source on Google. ZDNET’s key takeaways A new feature lets Claude Managed Agents refine their memories. Managed Agents speeds agent build and deployment 10x.  Anthropic continues to anthropomorphize its products.  AI agents seem to get new capabilities almost every day. Now, Anthropic says its agents can dream.  Claude Managed Agents, which Anthropic released on April 8, lets anyone using the Claude Platform create and deploy AI agents. The suite of APIs handles the time-consuming production elements developers go through to build agents, letting teams launch agents at scale — 10 times faster, as Anthropic said in the release. Also: The 5 myths of the agentic coding apocalypse On Wednesday, during its Code with Claude event, Anthropic updated Managed Agents with a new feature called “dreaming,” which lets agents “self-improve” by reviewing past sessions for patterns, according to Anthropic. Building on an existing memory capability, the feature schedules time for agents to reflect on and learn from their past interactions. Once dreaming is on, it can either automatically …

Anthropic’s Little Brother – The Atlantic

Anthropic’s Little Brother – The Atlantic

Published by Sam Flores

OpenAI does not like to be left out. The week after Anthropic announced Claude Mythos Preview—an AI model that has put governments around the world on edge because of its potential ability to hack into banks, energy grids, and military systems—OpenAI shared a program that is uncannily similar. And just like Anthropic did with its model, OpenAI has, for cybersecurity purposes, restricted access to this new bot, called GPT-5.4-Cyber, to a small group of trusted users. This sequence has become something of a pattern: First Anthropic will make an announcement, and then OpenAI will follow suit. Last year, Anthropic launched Claude Code, an AI coding tool. A couple of months later, OpenAI came out with its own version, Codex. When Claude Code had a breakout moment in January, OpenAI responded with two major updates to Codex alongside a press blitz for the product. And earlier this month, OpenAI released a version of Codex that allows it to use other apps on your desktop—similar to an existing Anthropic tool called Claude Cowork. Until recently, Anthropic—founded by …

As researchers and practitioners debate the impact that new AI models will have on cybersecurity, Mozilla said on Tuesday it used early access to Anthropic’s Mythos Preview to find and fix 271 vulnerabilities in its new Firefox 150 browser release. Meanwhile, researchers identified a group of moderately successful North Korean hackers using AI for everything from vibe coding malware to creating fake company websites—stealing up to $12 million in three months. Researchers have finally cracked disruptive malware known as Fast16 that predates Stuxnet and may have been used to target Iran’s nuclear program. It was created in 2005 and was likely deployed by the US or an ally. Meta is being sued by the Consumer Federation of America, a nonprofit, over scam ads on Facebook and Instagram and allegedly misleading consumers about the company’s efforts to combat them.

OpenAI’s GPT-5.5 is here, and it’s no potato: narrowly beats Anthropic’s Claude Mythos Preview on Terminal-Bench 2.0

OpenAI’s GPT-5.5 is here, and it’s no potato: narrowly beats Anthropic’s Claude Mythos Preview on Terminal-Bench 2.0

Published by skeptic

After months of rumors and reports that OpenAI was developing a new, more powerful AI large language model for use in ChatGPT and through its application programming interface (API), allegedly codenamed “Spud” internally, the company has today unveiled its latest offering under the more formal name GPT-5.5. And to likely no one’s surprise, it’s hardly a “potato” in the disparaging sense of the word: GPT-5.5 retakes the lead for OpenAI in generally available LLMs, coming ahead of rivals Anthropic’s and Google’s latest public offerings, and even beating the private Anthropic Claude Mythos Preview model narrowly on one benchmark (essentially a statistical tie). “It’s definitely our strongest model yet on coding, both measured by benchmarks and based on the feedback that we’ve gotten from trusted partners, as well as our own experience,” explained Amelia “Mia” Glaese, VP of Research at OpenAI, in a video call with journalists ahead of the launch earlier today. OpenAI positions GPT-5.5 as a fundamental redesign of how intelligence interacts with a computer’s operating system and professional software stacks. “What is really …

Do you need to worry about Mythos, Anthropic’s computer-hacking AI?

Published by skeptic

Anthropic’s Project Glasswing aims to improve online security Jonathan Raa/NurPhoto via Getty Images) The past few weeks have brought apparently alarming news of Mythos, an AI that can identify cybersecurity flaws in a matter of moments, leaving operating systems and software vulnerable to hackers. The cybersecurity community is now beginning to get a better sense of how Mythos may change the face of cybersecurity – and not necessarily for the worse. What is Mythos and why are people concerned by it? Mythos is an AI created by Anthropic. Its existence was accidentally revealed last month when people unearthed content on the company’s website, not due for publication, which had been left unsecured for anyone to see. According to Anthropic, there’s a good reason the model had been kept behind closed doors: it is – by accident rather than design – extremely good at hacking. It can allegedly discover flaws in virtually any software, if asked, that would allow the user to break in. The company says that Mythos found thousands of high- and critical-severity vulnerabilities …

Sign up to see the future, today Can’t-miss innovations from the bleeding edge of science and tech Remember Claude Mythos, Anthropic’s new AI model that it hyped as being so powerful that it was too dangerous to release to the public? Well, it’s already been broken into, according to new reporting from Bloomberg. A small group of Discord users gained access to a preview version of Mythos, a source told the outlet, on the same day Anthropic announced it would be exclusively releasing the model to a select ring of companies. “We’re investigating a report claiming unauthorized access to Claude Mythos Preview through one of our third-party vendor environments,” a spokesperson for Anthropic told Bloomberg in a statement. The company added that it hasn’t found any evidence of unauthorized access to Mythos. The group supposedly doesn’t have any nefarious intentions. It has been regularly using Mythos since gaining access to it, according to Bloomberg, though only for non-cybersecurity related purposes. The source described the group as being interested in “playing around” with new models, rather …

The UK’s top cybersecurity official has told Sky News that AI models such as Mythos are “warning shots” for the UK about the danger of powerful AI. Richard Horne, the head of the National Cybersecurity Centre, stressed the need for organisations to improve their cyber defences, saying they needed to act with “10 times urgency”. But he said he did not consider AI a national security threat at present, as new models were “not finding new attacks, they’re just exposing more security vulnerabilities”. He added: “We’re in a kind of perfect storm where we have two forces – one huge technology disruption, one rising geopolitical tensions, and they come together. And cybersecurity’s in the middle of them.” Image: Richard Horne. File pic: PA Anthropic’s new model Mythos has been causing widespread concern after the AI firm announced that it was significantly better at finding cyber vulnerabilities than previous AIs. The company decided not to release Mythos publicly, instead sharing it with a select set of companies and organisations – including the UK AI Security Institute, …

Unauthorized group has gained access to Anthropic’s exclusive cyber tool Mythos, report claims

Published by skeptic

A group of unauthorized users has reportedly gained access to Mythos, the cybersecurity tool recently announced by Anthropic. Much has been made of Mythos and its purported power — an AI product designed for enterprise security that, in the wrong hands, could become a potent hacking tool, according to the company. Now Bloomberg has reported that a “private online forum,” the members of which have not been publicly identified, has managed to gain access to the tool through a third-party vendor. “We’re investigating a report claiming unauthorized access to Claude Mythos Preview through one of our third-party vendor environments,” an Anthropic spokesperson told TechCrunch. The company said that, so far, it has found no evidence that the supposedly unauthorized activity has impacted Anthropic’s systems in any way. The unauthorized group tried a number of different strategies to gain access to the model, including using “access” enjoyed by the person who was interviewed by Bloomberg. That person is currently employed at a third-party contractor that works for Anthropic, the outlet reported. Members of the group are …
