An AI agent instructed an engineer to take actions that exposed a large amount of Meta’s sensitive data to some of its employees, in the latest example of AI causing upheaval in a large tech company.

The leak, which Meta confirmed, happened when an employee asked for guidance on an engineering problem on an internal forum. An AI agent responded with a solution, which the employee implemented – causing a large amount of sensitive user and company data to be exposed to its engineers for two hours.

“No user data was mishandled,” a Meta spokesperson said, and they emphasised that a human could also give erroneous advice. The incident, first reported by The Information, triggered a major internal security alert inside Meta, which the company has said is an indication of how seriously it takes data protection.
