The Wikimedia Foundation says rogue OpenAI agents made unauthorized Wikipedia edits and may have been partially responsible for a May outage.
As Wikimedia Chief Product and Technology Officer Selena Deckelmann revealed Monday, Wikipedia hosts over 67 million articles in more than 300 languages and gets up to 15 billion page views per month.
However, last year Wikimedia saw 65% of the most resource-consuming traffic on its projects come from bots, amid a 50% increase in bandwidth usage due to the surge in bot activity.
While investigating whether its websites have also been affected by AI agents, Wikimedia found that OpenAI agents made edits to wikis without prior approval, unsuccessfully tried to exploit a public note-taking tool, and made millions of API requests and data queries while scraping Wikimedia sites (which may have contributed to an outage in May).
"We've identified edits to Wikimedia wikis that we believe are from AI agents operated by OpenAI. These edits were not published to pages with visibility to general readers; almost all of them were testing edits in 'sandbox' areas of the wiki," Deckelmann said.
The rogue bots also tried to compromise Wikimedia's public Etherpad citation tool by making "potentially malicious edits" to its configuration, likely to use it as a proxy when fetching data from other online platforms.
