The hacker "exfiltrated an estimated 12 to 26 GB of database dumps, including information on political party donors and member records."
A French-speaking hacker used Claude to build and refine a targeting and hacking infrastructure aimed at roughly 40 European political organizations, Anthropic disclosed in a security report published September 10. Of 42 tracked targets — the majority French and associated with the far right, including at least one political party, a training institute, and several news outlets — the hacker gained internal access to 14 and walked away with an estimated 12 to 26 GB of database dumps containing donor records and party membership data.
Among the confirmed victims was Frontières, a French far-right magazine whose comments section was compromised via injected spyware; the site has since disabled comments entirely. Anthropic did not name the other targets. The case is one of the cleaner real-world examples of an AI model being used to operationalize a cyberattack from end to end, from target research through intrusion.
