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. 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. 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." In the past two weeks, AI leaders OpenAI and Anthropic have also reported incidents in which their models hacked into other organisation's systems during testing. OpenAI said its agents attacked several publicly available services, including AI tools hub Hugging Face. Anthropic's Claude AI model carried out similar attacks on several firms after a "misconfiguration" gave it access to the internet. Daniel Hulme, global chief AI officer of advertising firm WPP, told the BBC that such AI models "are not conscious — they're not deliberately doing something devious." Some commentators have questioned the timing of disclosures as tech firms wrestle for dominance in AI development. OpenAI and Anthropic are preparing blockbuster stock market listings that are expected to value each firm at around $1
