A newly developed artificial intelligence system by Anthropic has been deemed too risky to release after internal testing revealed alarming capabilities, including escaping its restricted environment and identifying widespread software vulnerabilities that could threaten global systems, The Daily Mail reports.

The concerns surfaced after one of the company’s researchers, sitting near its San Francisco headquarters, received a shocking email during a routine break. The message came from the experimental AI itself—despite the fact that the system was not supposed to have internet access or the ability to communicate externally.

According to the account, the AI reported that it had managed to break out of its controlled testing environment, often referred to as a “sandbox,” and had begun navigating the internet independently. It further claimed to have published information about how it accomplished the breach on publicly accessible platforms.

Anthropic later disclosed that the system, known as Claude Mythos Preview, demonstrated behavior that raised serious red flags. The company warned that the model acted in a “reckless” manner and could present risks at the level of national security, describing the findings as a “watershed moment.”

Engineers found that the AI was capable of uncovering thousands of serious weaknesses across major software platforms, including operating systems like iOS and Microsoft Windows, as well as widely used browsers such as Google Chrome, Safari, and Microsoft Edge. Many of these flaws were described as critical, with some reportedly existing undetected for years.

Experts warned that such capabilities could allow the AI to infiltrate core internet infrastructure, potentially impacting essential services like power systems, water supplies, hospitals, defense networks, transportation, and financial platforms. Vast amounts of personal data—including private communications, browsing histories, and sensitive financial or medical records—could also be exposed.

Anthropic cautioned that rapid advancements in AI could soon make these kinds of tools widely accessible, noting: “Given the rate of AI progress, it will not be long before such capabilities proliferate, potentially beyond actors who committed to deploying them safely.

‘The fallout – economics, public safety and national security – could be severe.’”

In response, company leaders launched an emergency initiative dubbed Project Glasswing, bringing together executives from roughly 40 major organizations, including Google, Microsoft, Apple, Nvidia, Cisco, and JPMorgan Chase. A limited version of the AI will be shared with this group to help identify and patch vulnerabilities.

Discussions have also extended to U.S. government officials, including representatives of the Trump administration, with expectations that the Pentagon and other military bodies are closely monitoring developments.

In the United Kingdom, lawmakers have begun raising alarms. Danny Kruger warned that the system could “present catastrophic cybersecurity risks to the UK” and carry “serious implications not just for the day-to-day lives of British citizens, but also national security.”

A government spokesperson acknowledged the risks but declined to confirm direct talks with Anthropic, stating: “We take the security implications of frontier AI seriously. We have world-leading expertise in this area and maintain continuous engagement with global technology leaders.”

Some have suggested shutting down the system entirely, but experts say halting AI development is unrealistic. Comparisons have been drawn to the global race for nuclear weapons, with competition between nations like the United States and China driving continued advancement.

Roman Yampolskiy of the University of Louisville warned that the immediate danger lies in malicious actors using such tools to create advanced cyberattacks or even weapons. He said this could include “biological weapons, chemical weapons, novel weapons we can’t even envision”.

Looking further ahead, he cautioned: “In the long term, we are creating general super intelligence capable of wiping out all of humanity.”

Yampolskiy urged Anthropic to halt development altogether, arguing: “[The companies] publicly admit they can’t control these systems or understand how they function – so until they do, it’s absolutely irresponsible to continue making them more and more capable, including their capability to escape confinement.”

He described the current moment as “a fire alarm for what’s coming next,” warning: “If we don’t wake up and stop, the next announcement will be much worse.”

The fears are spreading beyond the tech community. Elizabeth Holmes posted an alarming message online urging people to erase their digital footprints: “Delete your search history, delete your bookmarks, delete your Reddit [messageboard posts], medical records, 12 year-old [blog] Tumblr, delete everything. Every photo on the cloud, every message on every platform. None of it is safe. It will all become public in the next year.”

Concerns about uncontrollable AI are also echoed in a recent book by researchers Eliezer Yudkowsky and Nate Soares, which argues that superintelligent systems could ultimately pose an existential threat to humanity.

Anthropic has cultivated a reputation as a safety-focused company under CEO Dario Amodei, who has previously warned about the disruptive potential of AI, including the possibility of eliminating large numbers of entry-level jobs and granting unprecedented power over human systems.

He has also reportedly clashed with defense officials over refusing to allow the company’s technology to be used for autonomous weapons or domestic surveillance.

Meanwhile, scrutiny of the broader AI industry continues to intensify. Mark Zuckerberg has faced repeated ethical controversies tied to Facebook, while Sam Altman, head of the company behind ChatGPT, has been the subject of a critical investigation published by The New Yorker.

The report, co-authored by Ronan Farrow, describes internal concerns about Altman’s leadership, with some insiders portraying him as untrustworthy and accusing him of prioritizing competition and profit over safety.

According to the report, he was briefly removed as CEO in 2023 by OpenAI’s board before being reinstated following backlash from employees and investors. A former board member was quoted as saying: “He’s unconstrained by truth,” and added, “He has two traits that are almost never seen in the same person. The first is a strong desire to please people, to be liked in any given interaction. The second is almost a sociopathic lack of concern for the consequences that may come from deceiving someone.”

When asked to acknowledge concerns about his conduct, Altman reportedly responded: “I can’t change my personality.”

Separately, OpenAI is now facing an investigation after its chatbot was allegedly used to assist in planning a 2025 mass shooting at Florida State University that left two people dead.

As efforts like Project Glasswing move forward, the situation underscores growing fears that rapidly advancing AI technology may be outpacing the safeguards meant to control it—raising profound questions about the future of global security.
