Crédit Mutuel Arkéa Says Attackers Drained Its Own Account and May Have Cashed Out in Crypto

Crédit Mutuel Arkéa, the French banking group, confirmed on November 4 that it had suffered an attack through which fraudulent activity was processed. A follow-up statement the same day said the attackers may have converted the money into crypto by sending transactions from the bank's own account to other banks. The bank did not confirm the reported €118 million ($133 million) loss, saying it could only validate the rough scale. Some of the money has been frozen and recovery steps are underway. Arkéa also disputed media accounts placing the entry point at its online bank Fortuneo. The onchain investigator ZachXBT had earlier named the bank as the victim and put the total at $133 million.
Why it matters: The bank's account of the route differs from the investigator's, who tied the funds to exchange accounts rather than the bank's own account.
