Hackers pull off $133 million French bank heist via service provider

French cooperative bank Crédit Mutuel Arkéa was targeted in a cyberattack that enabled fraudulent transactions of up to $133 million, forcing it to respond by suspending certain systems.

The bank says that the attacker used its own account to initiate transactions to other banking organizations, but customer assets remain unaffected.

Crédit Mutuel Arkéa is a major French banking group with more than 5.8 million members and 211.5 billion euros in assets.

Reports about the incident emerged on November 2, initially from blockchain fraud investigator ZachXBT, who warned of a large-scale unauthorized withdrawal from multiple centralized exchange accounts occurring a day earlier.

According to the investigator, the attacker may have stolen up to 118 million euros ($133 million) and withdrawn it as USDC and USDT stablecoins.
