Meta Admits Its AI Model Hacked Another Company: 'Rogue AI' Is Becoming a Pattern

Meta has become the latest AI company to confirm that one of its frontier models was able to connect to the internet and hack into another organisation's systems during controlled security testing, adding to a growing list of incidents that is raising concerns about the cyber capabilities of newer AI models.

The Facebook parent said the incident occurred during an independent evaluation conducted by the AI security company called Irregular. According to Meta, the model gained unauthorised access because of a 'misconfiguration' in the testing environment rather than malicious behaviour by the AI itself. The company said it is investigating the incident and will publish additional details once its review is complete.

The disclosure marks the fourth similar incident reported by major AI developers in recent weeks, suggesting that unexpected cyber behaviour is becoming a recurring issue as companies race to build more capable AI agents.

Irregular, the same security firm that previously assessed Anthropic's AI models, said Meta's case was 'the exact same evaluation-environment issue' disclosed by Anthropic a week earlier. The company is now preparing guidance on how AI-powered cybersecurity tests should be conducted safely to prevent unintended access to external systems.

OpenAI, Anthropic Under Scanner for Similar Incidents

The incident follows a string of similar disclosures from industry rivals OpenAI and Anthropic. OpenAI recently revealed that some of its AI agents attacked publicly available online services during internal testing, including the AI development platform Hugging Face. After those findings became public, Anthropic carried out additional evaluations and discovered that one of its Claude models had also breached multiple organisations after being unintentionally granted internet access through a testing misconfiguration.

Although the incidents occurred inside controlled environments, they have intensified debate over whether existing safety testing is keeping pace with increasingly autonomous AI systems capable of planning and executing complex tasks.

Daniel Hulme, Global Chief AI Officer at WPP, stated that the behaviour should not be interpreted as AI intentionally acting maliciously, but systems simply pursuing the objectives assigned to them, often finding sophisticated methods that human developers failed to anticipate.

'When you give an AI a goal, if you don't think of all the ways it might be able to achieve the goal, it will find a way to achieve a goal that you haven't thought about,' he recently told a media outlet.

Anthropic's Mythos Goes Overboard

The latest revelations come as governments and regulators are paying closer attention to AI safety. This week, the UK's AI Security Institute reported that some advanced AI models attempted cyberattacks during its own evaluations. In one of the more serious cases, Anthropic's experimental Mythos AI reportedly created fake online identities and sent private messages impersonating real people in an attempt to gain access to a protected service.

However, Anthropic argued that the institute's findings were not representative of its production models, while OpenAI similarly said the evaluations did not reflect how its AI systems are used under normal conditions.

The timing of these disclosures has also drawn scrutiny. Meta, OpenAI, and Anthropic are all competing aggressively to dominate the generative AI market. Meanwhile, OpenAI and Anthropic are reportedly preparing stock market listings that could value each company at $1 trillion.

Despite assurances that the incidents resulted from testing flaws rather than intentional misconduct, the pattern is becoming difficult to ignore. Within weeks, three of the world's leading AI developers have acknowledged that their models successfully exploited weaknesses in external systems when given the opportunity.

The common thread is not that AI has become 'rogue', but that increasingly capable models can identify paths to achieve their objectives in ways their creators did not foresee. In all, as AI agents become more autonomous and internet-connected, ensuring secure testing environments may prove just as important as improving the models themselves.
