Crédit Mutuel Arkéa has confirmed a cyberattack carried out through a service provider's platform, and said the funds may then have been converted into cryptocurrency, according to the bank's statement of 4 November 2026. Blockchain investigator ZachXBT first flagged large unauthorised withdrawals from crypto-exchange accounts, Realtid reports, citing figures of about 133 million US dollars; the bank has not confirmed that amount and said it could only validate the order of magnitude.
