Crédit Mutuel Arkéa Reports About $100 Million Stolen in External Hack

Overview

• Crédit Mutuel Arkéa confirmed late Wednesday that a sophisticated external attack has been contained and that the bank is assessing losses estimated at roughly $100 million.
• The bank said attackers accessed a bank account to push transfers to other institutions but that customer accounts were not affected.
• Independent blockchain tracker ZachXBT flagged large suspicious fund movements that, along with media reports, indicate some of the stolen money was converted into cryptocurrencies on trading platforms.
• The Paris public prosecutor opened a formal investigation into an alleged attack on automated data‑processing systems by an organized criminal group and investigators are working to trace and recover cross‑border crypto flows.
• The case follows a similar high‑profile crypto-related incident at Binance this week and highlights growing risks from attacks that turn rapid interbank transfers into hard‑to‑trace cryptocurrency movements.
