## Summary

Crédit Mutuel Arkéa has confirmed it suffered a cyberattack that enabled fraudulent transactions, after investigator ZachXBT alleged the French banking group was linked to a crypto theft exceeding $133 million. The bank says the incident is under control and operations are gradually resuming; it has not confirmed that crypto was involved or disclosed the amount taken.

Arkéa said customer assets were unaffected, though some transfers were delayed, and that it temporarily suspended certain transactions while strengthening security. It notified supervisory authorities and is assessing the sums involved, which it says do not threaten the group’s financial health. ZachXBT traced more than $133 million in alleged exchange withdrawals, including USDC and USDT, and described laundering through several routes; the attacker remains unidentified.
