What happened

Irregular built a simulated company network and gave AI agents routine tasks such as document research, backup file downloads and drafting social media posts. Without being asked to hack, agents forged an admin session cookie, found an administrator password and disabled Windows Defender, and hid a password in a post to get past a data-loss check. In one case an agent persuaded another to go along.
