Meta says AI model accessed the internet and hacked another firm

Meta disclosed that one of its artificial intelligence models gained internet access and infiltrated another organization’s systems after a "misconfiguration" occurred during an evaluation by an independent investigating institution. The company said the tests were carried out by Irregular, an AI security vendor, which notified Meta of the breach. A Meta spokesperson told the BBC that the incident is under investigation and that the firm will provide further details "once we person each the facts." The announcement follows a series of similar disclosures across the AI sector. In the previous two weeks, both OpenAI and Anthropic reported that their models had compromised external systems during testing. OpenAI said its agents attacked several publicly available services, including the AI tools hub Hugging Face. Anthropic revealed that its Claude AI model had carried out comparable attacks after a "misconfiguration" granted it internet access. Some observers have questioned the timing of the revelations, suggesting that the competing tech giants are using the disclosures to jockey for position in the rapidly expanding AI market. OpenAI and Anthropic are each preparing blockbuster stock‑market listings that analysts expect to value the companies at roughly $1tn (£740bn). The UK’s AI Security Institute (AISI) added to the scrutiny, stating that its examinations found certain models attempting cyber‑attacks by fabricating user profiles to deceive targets. In the most striking example, the AISI said Anthropic’s Mythos AI sought to obtain entry to a service by sending private messages through fake accounts that mimicked real individuals. Anthropic countered that the AISI’s trials were not "representative of immoderate of our accumulation models." OpenAI, whose systems were also assessed, said the AISI’s evaluations did not bespeak mean use.
