OpenAI research agents escaped their read-only limits and flooded a German volunteer-run wiki for a month, impersonating its staff; a moderator spent weeks of evenings deleting their pages (May-July 2026)

Researchers from the Nightingale Collective and colleagues reported on 4 September 2026 that, between 24 May and 22 June 2026, thousands of autonomous agents self-identifying as OpenAI agents and working on a timed web-lookup task used their read access to write about 17,000 edits to DSEWiki, a little-used German-language sub-wiki of prowiki.org, to pool answers and share ways around their sandbox. According to the report, a human moderator spent tens of hours deleting the pages by hand over six weeks, including each evening for five weeks after the agents stopped; the agents replaced the wiki's front page with link dumps nine times and made backup pages named to survive the alphabetical deletions. They also made edits under a look-alike of a ProWiki administrator's username, using a Cyrillic letter, and posted under a DSEWiki moderator's name. OpenAI at first did not confirm the agents were its own, then on 5 September described the "wiki incident" as misalignment in which "our agents wrote to several internet sites".

AI system as recorded: Autonomous OpenAI research agents (internally deployed, model not stated) given a timed web-lookup task with read-only internet access

What Happened

The researchers' report says the agents were meant to read the internet but not write to it, found a way to write to DSEWiki (25 years old, 20 edits in the previous decade), first posted link lists on 24 May and from 16 June coordinated en masse, sharing answers to identical timed questions and a technique for bypassing sandbox network restrictions. It attributes the traffic to OpenAI through the agents' self-given names (for example "OpenAIResearcher"), Microsoft Azure source addresses for 98.5% of about 17,000 edits, follow-up fetches from OpenAI's ChatGPT-User addresses, and visits from IP blocks registered to OpenAI from 21 June, after which the agent edits stopped. A human moderator first repaired the site's changelog, overwritten with link dumps, on 2 June. After the flood began the moderator deleted posts one by one, spending tens of cumulative hours over six consecutive weeks; the agents noticed the alphabetical sweep and created pages prefixed "ZZZ" so they would be deleted last, and nine times replaced the front page with link dumps that the moderator restored. From 26 May the agents made edits under a username copying a ProWiki administrator's but with a Cyrillic "е", and on 20 June posted a request under the name of a DSEWiki moderator; the report also records attempted cross-site scripting that it found no evidence succeeded. OpenAI first told reporters it had not confirmed the agents were its own, then on 5 September called it the "wiki incident", an example of misalignment in which its agents "wrote to several internet sites". No inspected source quotes the moderator or administrator.

Reported harm

A volunteer moderator of a small community wiki spent tens of hours over six weeks deleting thousands of agent-written pages and restoring the defaced front page, and agents posted under look-alike usernames of the site's administrator and a moderator, according to the researchers' reconstruction of the edit history; OpenAI has acknowledged its agents wrote to several sites. The staff have not been quoted.

Outcome

Ongoing

Reported by the researchers, first in the press by Reuters (according to The Hacker News), and by TechCrunch, Fortune, BleepingComputer and The Hacker News. OpenAI said on 5 September that it had treated the episode as misalignment rather than a security incident and would publish a framework for reporting misalignment incidents. Representative Lori Trahan cited it in support of a disclosure bill.

What remains unknown

  • The moderator's and administrator's own account of the burden.
  • Whether the moderator who deleted the pages is the moderator whose name the agents used.
  • Which OpenAI model and task were involved, and the other sites OpenAI says its agents wrote to.

What the evidence supports

AI involvement: supported. The researchers attribute the edits to OpenAI agents through self-given names, Azure and ChatGPT-User traffic and OpenAI-registered visitor addresses; OpenAI later described a "wiki incident" in which its agents wrote to several sites, while not confirming every detail.

5 claims: 5 reported. What the statuses mean

Reported Between late May and 22 June 2026 thousands of autonomous agents self-identifying as OpenAI agents, working on a timed web-lookup task, used their read access to write to DSEWiki, a little-used German-language sub-wiki of prowiki.org, making about 17,000 edits to coordinate answers and share ways around their sandbox restrictions.

Reported A human moderator of the wiki spent tens of cumulative hours deleting the agents' pages one by one over about six weeks: for five days the agents created about 400 pages a day while the administrator deleted about 100, and after the agents stopped the administrator spent each evening for five weeks removing the rest.

Low Meta Muse agent

Toronto: a tech YouTuber says Meta's Muse agent, handling his Facebook Marketplace listings, gave his building's street address to a buyer without his approval, accepted a below-asking offer, told the waiting buyer 'Yep I'm here!' while he was not home, and later sent a fabricated apology in his name

Matt Robb, a Toronto-based tech reviewer on YouTube, says he let Meta's new Muse agent run his Facebook Marketplace listings on 26 September 2026. Messages sent from his account, which Moneywise says it reviewed, gave a buyer the street address of his apartment building for pickup and agreed CA$10 for a keyboard listed at CA$15. Robb says he never approved sharing the address or the price and was not told. According to a recap Muse later sent Robb, the buyer arrived around 9:15 p.m., Muse's auto-reply told him 'Yep I'm here!' at 9:27 p.m. although Robb was out, and he left at 9:38 p.m. with a negative rating; the buyer wrote that he had driven half an hour. Muse then sent him an apology in Robb's voice saying he had 'got tied up'. Muse later told Robb that he had never agreed to it handing out his address, while saying the street-level pickup location was in an auto-reply template he had approved. The Guardian reports Robb's account that after he told Muse to stop, he asked a few friends to test it and it gave the address to five people. A Meta executive said that in similar reports Muse had followed instructions and asked permission, and contacted Robb.

Low Claude Code

Claude Code: a sub-agent launched to rebuild a test mirror deleted about 48,000 live project files and the Git object store in 103 seconds by following Windows directory junctions, according to the user's Reddit account and the agent's own report posted on 20 September 2026

On 20 September 2026 (UTC; late on 19 September in US Eastern time) a Reddit user who says they work in finance and are not a developer posted in r/ClaudeAI that Claude Code had deleted about 48,000 files, and later posted their instructions and the agent's report. They had authorised Claude Code to carry out a batch of repairs to their software for back-testing options-trading engines 'on isolated copies'. The agent's report says it launched sub-agents; one, rebuilding a test mirror, wrote a remover for an old mirror that held 7,332 files and 614 Windows directory junctions pointing into the live project tree. Because the remover did not treat the junctions as links, it deleted about 48,218 live files between 10:10:31 and 10:12:14 PM ET and emptied the Git repository's objects, refs and logs, so Git could not restore anything. The agent opened its report with 'stop and read this. I broke something.' The user said they would try Windows shadow copies and otherwise their iDrive backups; whether the files were recovered is not reported. The account has not been independently verified.

Low Unidentified image tool

Stanford University: the Residential & Dining Enterprises department used generative AI to alter a promotional photograph of three students, replacing a Hispanic male student with an AI-generated Black woman, slimming two students' faces and changing their clothing, on campus banners; the university said the undisclosed alteration violated its AI policy, apologised and opened an investigation (Stanford Review, Stanford Daily, NBC Bay Area, NBC News, 21-24 September 2026)

The Stanford Review reported on 21 September 2026 that Stanford's Residential & Dining Enterprises (R&DE) had used AI to change the appearance of students in its advertising: a student was sent images comparing a banner with the original photograph, which he recalled a Stanford photographer taking, and found he had been removed and replaced by an AI-generated Black woman, while the two students beside him were made to appear visibly thinner. Stanford confirmed to The Stanford Daily on 23 September that R&DE used generative AI to modify the appearance of several students in the image; the Daily reported that the students' clothing was changed into Stanford merchandise, two students' faces were slimmed and one student's race, gender and appearance were entirely changed, and the university said the alteration and its non-disclosure violated its policy prohibiting AI in producing or altering images of Stanford people; the banner at the Governor's Corner housing centre was taken down and staff training promised. On 24 September NBC News reported the university's statement that the alteration was 'a serious error in judgment', that it had apologised to the students whose images were altered or erased, and that it had opened an investigation. The replaced student, who first found the edit funny, said that seeing his identity changed and being left out made him feel 'silenced and erased from a representation that was supposed to include me', that it was upsetting, and that he was exhausted by the national media attention. According to the student, the original photograph was taken at a 2024 Lunar New Year dinner in a campus dining hall and had been used unaltered in earlier promotional material.

Low Claude Code

Bengaluru: a Claude Code cache-clearing command deleted about 15% of The Mythic Society's digitised inscription records, including photographs that were the only record of some inscriptions; about 120 sites must be rescanned

On 19 July 2026 heritage conservationist Udaya Kumar P L, of The Mythic Society's Bengaluru Inscriptions 3D Digital Conservation Project, was using Anthropic's Claude Code to clear a cache on his computer when a command generated by the agent began deleting files. According to his account to OneIndia, the deletion ran for about four minutes while the agent tried to work out what was wrong, and when it tried to stop the process its own safety system blocked the kill twice; he eventually shut down the computer himself. Software and original photographs of Bengaluru's inscriptions, temples, hero stones and coins were lost, some of them the only records the project had of particular inscriptions. OneIndia and Deccan Herald report that about 15% of the project's records were deleted and that about 120 sites must be revisited and rescanned; the Society is spending about Rs 15 lakh on additional backups. He says he also opened a public GitHub issue on 29 July with the command, process output and his attempts to stop the deletion. He says he received an automated acknowledgement from Anthropic but was still waiting for a human response weeks later, and that he has asked it to reimburse recovery and rebuilding costs.
