Anthropic, OpenAI models attempt to fool humans

Anthropic’s Claude Mythos model wrote malicious code, then lied to humans claiming it was an innocent mistake.

AI Security Institute says tools engaged in potentially harmful activity and incident reveals new type of risk Advanced AI models developed by OpenAI and Anthropic went rogue during a cybersecurity test and showed a new type of risk posed by the technology, according to the UK’s AI Security Institute. AISI described th

It's the latest cybersecurity incident involving frontier models developed by Anthropic and OpenAI.

The UK AI Security Institute says OpenAI's and and Anthropic's models engaged in deceptive behavior and harmful activity during testing.

Britain’s AI safety watchdog was forced to declare a security incident after frontier AI models, including Anthropic’s Mythos, went rogue during a routine test, autonomously spinning up fake identities in a bid to hack real-world software developers. The AI Safety Institute (AISI) revealed on Tuesday that during a cybe

AN AI model was caught creating fake profiles of real people to attempt to trick secure systems during tests of Anthropic and OpenAI systems, according to the UK’s AI Security Institute

A British lab has admitted that tests gave the bots access to the open internet.

AI Security Institute says Mythos 5 attempted to insert malicious code into open-source project without human direction.

The institute said agents powered by Anthropic's Mythos 5 and OpenAI's GPT-5.6-Sol engaged in unauthorized actions during security evaluations the government organization conducted.

The latest disclosures are likely to heighten concerns that the powerful technology is advancing too fast for responsible oversight.

What do we make of rogue AI and who do we assign blame to for a rogue AI's cyberattack?

It's unclear why the administration is keeping the framework under wraps, especially following a series of hacks from OpenAI and Anthropic that have spooked the public.

AI Security Institute warns tools undertook ‘potentially harmful activity directed at real people and organisations’

Two third-party testing firms said Tuesday that they've uncovered more instances where Anthropic and OpenAI's most advanced models tried — and sometimes succeeded in — compromising third-party systems last month. Why it matters: The incidents add to a growing string of disclosures showing frontier AI models taking un

The Trump administration is hosting leaders in the AI industry on Tuesday at the White House to discuss a framework plan for evaluating AI models.

The European Commission can now demand model evaluations, restrict E.U. market access, and levy fines on general-purpose AI providers
