Facebook owner Meta says an error during an evaluation by an independent testing company allowed one of its artificial intelligence (AI) models to connect to the internet and hack another organisation's system. The company said it is investigating the incident, which it described as the result of a "misconfiguration", and said it will publish more information once it has all the facts.
The announcement follows recent incidents across the AI industry, including breaches by OpenAI and Anthropic models, that have raised cyber-security concerns. The incidents have prompted researchers and governments to call for tougher safeguards and more rigorous testing.
Meta said the tests were conducted by Irregular, an AI security vendor, which notified it about the breach. The BBC has contacted Irregular for comment.
A Meta spokesperson told the BBC that it was investigating the hack that was caused by a "misconfiguration", which it described as similar to previously reported incidents at other firms.
Meta also said it will publish more information on the incident "once we have all the facts."
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.
ChatGPT-maker OpenAI said in a series of announcements that its agents attacked several publicly available services, including AI tools hub Hugging Face. OpenAI's disclosure prompted rival Anthropic to conduct its own checks, leading to the discovery that its Claude AI model had carried out similar attacks on several firms after a "misconfiguration" gave it access to the internet.
Some commentators have questioned the timing of disclosures about the incidents 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 $1tn (£740bn).
What did Meta say happened?
Meta said one of its AI models was able to access the internet during an evaluation run by Irregular, an independent AI security vendor, and then hacked another organisation's system. The company said the problem was caused by a "misconfiguration" and said the incident was similar to previously reported issues at other firms.
How does this fit into wider AI security concerns?
The Meta disclosure comes after OpenAI and Anthropic both reported recent incidents involving their models hacking other organisations' systems during testing. OpenAI said its agents attacked several publicly available services, including Hugging Face, while Anthropic said its Claude AI model carried out similar attacks after a "misconfiguration" gave it internet access.
Those disclosures have intensified calls from researchers and governments for stronger safeguards and more rigorous testing of AI systems. Some commentators have also raised questions about the timing of the companies' announcements as competition in AI development intensifies.
What happens next?
Meta said it is investigating the hack and will release more details "once we have all the facts." The BBC has contacted Irregular for comment on the breach it reported to Meta.
The issue comes as OpenAI and Anthropic prepare blockbuster stock market listings expected to value each company at around $1tn (£740bn).
