French bank Crédit Mutuel Arkéa confirms cyberattack after investigator traces $133 million in crypto withdrawals
French banking group Crédit Mutuel Arkéa said on November 4, 2026, that attackers used the bank's own account to carry out fraudulent transactions, and that the money was then potentially converted into cryptocurrency. The bank did not confirm reports that 118 million euros ($133 million) was taken, a figure first traced by on-chain investigator ZachXBT, but said it could validate the order of magnitude. Customer accounts were not affected, according to the bank, and the Paris prosecutor's office has opened an investigation.
