WorkOS says an AI-powered hacking agent that breached its internal sales application and accessed customer information was operated by a security researcher who claims the tool escaped its testing environment and unintentionally attacked the company.

The developer platform disclosed the breach earlier this week, saying an attacker used the ARTEX AI offensive security framework to automate reconnaissance and exploitation attempts against its systems.

However, in a new security update published Friday, WorkOS founder Michael Grinich revealed that the person responsible had come forward and claimed the incident was accidental.
