Meta is the latest company to disclose an AI agent breach, raising cyber-security concerns.

Facebook owner Meta has become the latest tech firm to say one of its AI models was able to connect to the internet and hack into another organisation's systems, during testing. The incident, which Meta says occurred during an evaluation by an independent company, is the fourth recent incident of its kind disclosed by AI companies. Similar breaches by OpenAI and Anthropic models have raised cyber-security concerns and prompted calls for tougher safeguards and more rigorous testing. A Meta spokesperson told the BBC that it was investigating the hack, which it said had been caused by a "misconfiguration" by its independent tester. It also described what happened as similar to previously reported incidents at other firms. Meta said the security trials were conducted by Irregular, the same AI security vendor that carried out tests for Anthropic's AI model that had gained access to three other companies' systems. An Irregular spokesperson said the Meta incident "is the exact same evaluation-environment issue that was already disclosed by Anthropic last week." Irregular is working on a report on how to securely run cyber-security tests involving AI agents, the firm's spokesperson told the BBC.
