Crédit Mutuel Arkéa Confirms Cyberattack After ZachXBT Ties It to $133M Crypto Theft

French cooperative bank Crédit Mutuel Arkéa has confirmed a cyberattack following allegations by blockchain investigator ZachXBT that the incident is linked to a $133 million cryptocurrency theft.

The bank stated the attack enabled “fraudulent operations” but did not specifically mention cryptocurrency in its public confirmation. It said it is still assessing the amounts involved. ZachXBT had earlier named the bank as the alleged victim of the theft, which he said occurred in mid-October.

The investigator’s post suggested the stolen funds were moved through various cryptocurrency mixers. The bank said it has filed a complaint with judicial authorities and that its technical teams are working with cybersecurity specialists.

This incident highlights the ongoing risks of cyberattacks targeting financial institutions with connections to the digital asset space. The full scope of the loss and the precise role of cryptocurrency in the attack remain under investigation.
