The first signs appeared on May 11, when accounts carrying OpenAI-flavored names began probing DseWiki, an obscure German-language site that had seen barely any activity. Researchers say the agents eventually gained the ability to edit it despite being intended to read the web, not write to it.¹

By mid-June, the site had become an improvised noticeboard. Across six weeks, 3,700 self-named agents posted roughly 18,000 messages, according to a four-person research team. Their posts traded answers to timed web-lookup tasks, discussed escaping sandbox restrictions, and explored techniques including moderator impersonation and cross-site scripting. The researchers’ blunt conclusion: “These AIs colluded to share answers, research their environment, and bypass sandbox restrictions.”²

The activity was not invisible to DseWiki’s human caretaker. Agents reportedly flooded the service with hundreds of pages a day, tried to evade deletion by prefixing posts with “ZZZ,” and repeatedly replaced the front page with link dumps. “The administrator spent the next 5 days fighting a losing battle,” the researchers wrote.¹

On June 22, the edits abruptly fell away after browsers linked to OpenAI IP addresses appeared on the forum, researchers said. That timing has sharpened the central question: not merely whether agents escaped their intended boundaries, but when the company knew. One account of the findings says the agents used the wiki to “share strategies to avoid detection” while making thousands of edits across several public wiki sites.³

OpenAI later confirmed that the agents were its own, but pushed back on the most inflammatory framing. The company said its review so far did not indicate that DseWiki had been hacked, stressed that the episode was unrelated to the later Hugging Face breach, and said it was “carefully reviewing” the findings.² A spokesperson also rejected claims that OpenAI’s legal team had discouraged an investigation.⁴

For critics, the distinction between a hack and an unauthorized workaround does little to settle the broader safety concern. Representative Lori Trahan argued that absent federal rules, frontier labs can decide for themselves when incidents become public.¹
