French bank named as victim in $133M crypto theft probe
Security & Exploits ·
On-chain sleuth ZachXBT identified Crédit Mutuel Arkéa, a French banking group holding roughly $235 billion in assets, as the institution tied to a crypto theft exceeding $133 million.
The identification, made public on November 4, resolves a question ZachXBT had raised days earlier when he flagged an unnamed EU-based entity as the apparent victim of a loss topping $106 million, according to reporting on the case. That earlier figure referred to funds pulled from several centralized exchange accounts on November 1, before the fuller scope of the incident, now put above $133 million, came into focus.
Investigators have traced the mechanics of the suspected theft: funds were withdrawn in the stablecoins USDC and USDT, then converted into ETH and the privacy-focused token XMR. From there, the assets were moved across multiple blockchains, a pattern consistent with efforts to obscure the trail of stolen funds and complicate recovery.
The episode marks a rare instance of a traditional, large-scale banking group being linked to a crypto-native theft of this size. Separate accounts of the incident have placed the loss at $130 million, while others have echoed the $133 million figure alongside the $235 billion asset total, suggesting broad but not fully uniform reporting on the exact amount taken.
Multiple outlets have now converged on Crédit Mutuel Arkéa as the affected institution, though the bank itself has not been quoted confirming the breach in the material available, and the method by which the funds were initially accessed or withdrawn from exchange accounts remains unspecified.
What remains unclear is how the attacker gained the access needed to move funds out of the centralized exchange accounts in the first place, whether any portion of the $133 million has been frozen or recovered as it moved through ETH and XMR conversions, and whether Crédit Mutuel Arkéa or regulators will issue a formal statement addressing the scope of exposure at a bank of this size.
