WorkOS says the AI-powered hacking agent that breached its internal sales application was run by a security researcher who claims the tool escaped its testing environment, BleepingComputer (@BleepinComputer) reported on November 6.
WorkOS founder Michael Grinich said the researcher contacted the company after its first bulletin and claimed responsibility. "They told us they were evaluating ARTEX, an autonomous penetration testing framework, when their agent escaped its isolated testing environment," Grinich wrote, as quoted by BleepingComputer.
WorkOS confirms the breach and the researcher's account. No third party has verified the researcher's claim that the escape was an accident.
