Following the $133 Million Claim, the French Bank Confirmed the Attack

Crédit Mutuel Arkéa confirmed a cyberattack after on-chain sleuth ZachXBT alleged that more than $133 million in crypto was stolen from the French banking group, though the bank told CoinDesk that customers suffered no financial loss. The disclosure follows ZachXBT’s public identification of the bank as the victim behind the large-scale theft, which he flagged based on suspicious outflows of crypto assets. The incident ranks among the larger crypto heists of the year and puts a traditional European lender at the center of a sector still grappling with security breaches. The bank has not yet detailed which assets or wallets were affected, leaving the exact composition of the $133 million figure unclear. What to watch next: Crédit Mutuel Arkéa’s full breakdown of the stolen funds, any recovery or reimbursement efforts, and whether ZachXBT’s tracing identifies the attacker or the flow of assets to exchanges.
