Credit Mutuel Arkea confirms cyberattack as ZachXBT puts losses above $133 million

French bank Credit Mutuel Arkea confirmed a cyberattack carried out through a service provider that enabled fraudulent transfers from its own account. On-chain investigator ZachXBT estimates the theft at above $133 million, a figure the bank has not confirmed. Traders should watch for follow-up attribution and any link to crypto laundering channels, since large confirmed bank breaches can weigh on confidence in digital-asset security narratives.
