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. 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".
