Hacker claims data theft from French parties

Between October 23 and 25, 2026, an hacker known as ChimeraZ claimed to have stolen data from three French political parties: the Communist Party of France (PCF), La France insoumise, and Renaissance.

PCF confirms data breach

The PCF confirmed an intrusion after being alerted by the National Cybersecurity Agency. The other two parties denied having been hacked.

Intrusion details revealed

The National Cybersecurity Agency warned the PCF on Friday, October 23. By evening, the party admitted that its members' and sympathizers' file had been leaked.

Sensitive data compromised

This file contains political opinions, which are classified as sensitive information under French law. The hacker claims to possess data on 190,000 individuals, including names, postal addresses, emails, and phone numbers.

Leak reportedly for sale

According to Le Parisien, the file was for sale as early as Saturday. The PCF assures that the theft did not include banking data, says it has immediately secured its systems, and announces it will file a complaint.
