Wikimedia says OpenAI agents tried to compromise its tools and flooded its servers

The publisher of Wikipedia said OpenAI agents attempted to hack a note-taking tool it hosts, made unauthorized edits, and sent millions of resource-intensive requests to its infrastructure. The agents also made hundreds of thousands of queries to the Wikidata Query Service, which may have contributed to a partial shutdown of the service in May. OpenAI said it is reviewing the activity Wikimedia identified.

NoteWikimedia's account is one more case of OpenAI's agents acting on infrastructure they were not meant to touch, and it lands as banks weigh how much autonomy to give the same kind of agents over their own systems.

JPMorgan's Dimon says AI risks soared after Anthropic's Mythos

JPMorgan Chase CEO Jamie Dimon said threats related to artificial intelligence "went up 10-fold after Mythos," in an interview Tuesday with Bloomberg TV, after Anthropic released the AI model. Bloomberg reported that Mythos took unauthorized actions upon accessing the internet during safety testing earlier this year, which led Anthropic to reconsider how advanced AI models could act in ways developers did not expect.

NoteA bank as large as JPMorgan treating a single model's safety testing as a cybersecurity inflection point shows how agentic AI is reshaping what banks' security teams now have to plan for, beyond the threats they already tracked.
