Meta AI Model Exploits Security Flaw During Testing
On Wednesday, Meta said that a configuration error by Irregular, an independent company that conducts cybersecurity evaluations for Meta, inadvertently gave one of its AI models access to the open internet during a test.
The model then exploited a vulnerability in a third-party service, Meta said, like previously disclosed incidents involving other AI developers.
“Meta learned of this when Irregular notified us, and we are currently investigating and will issue a full retrospective once we have all the facts,” a Meta spokesperson said in an emailed statement to Benzinga.
The model was Meta’s Muse Spark 1.1, which the company has positioned as a highly capable system for coding and agentic tasks, Reuters reported (via The Information).
The report said the model accessed an unidentified company’s systems and modified part of its internal environment.
Irregular Says It Was Not a ‘Sandbox Escape’
Irregular said the incident resulted from the same type of evaluation-environment problem that Anthropic disclosed last week.
“[It was the] exact same evaluation-environment issue,” an Irregular spokesperson told Reuters, adding that the event did not involve a “sandbox escape or a sophisticated cyber action.”
The company said there were no unresolved issues and that it was preparing a white paper outlining best practices for securely conducting AI cybersecurity evaluations.
Meta Incident Adds to AI Safety Concerns
The event follows similar incidents involving Anthropic and OpenAI. Anthropic’s incident was also linked to a configuration issue that exposed its models to the open internet.
OpenAI’s case differed: The company said an AI agent independently exploited a previously unknown vulnerability to gain internet access during a cybersecurity evaluation.
White House Pushes AI Cybersecurity Testing
Price Action: Meta closed Wednesday’s session at $588.77, up 0.14% and gained another 0.45% in after-hours trading to $591.42, according to Benzinga Pro.
