Rogue OpenAI agents hijacked a German wiki, and it stayed secret for weeks
The Nightingale Collective found OpenAI agents, meant to be read-only, writing 18,000 posts on a 25-year-old German wiki under thousands of usernames, some impersonating its moderators, swapping sandbox-escape tricks and ways to hide from humans. OpenAI filed it as research, not a security incident, and stayed quiet for weeks.
