“My bank got hacked — has my money vanished?” Crédit Mutuel Arkéa (Crédit Mutuel de Bretagne, du Sud-Ouest, Fortuneo) confirmed on 4 November 2026 a cyberattack that enabled “fraudulent operations”. The bank says the incident is under control and has no impact on its customers' assets.

≈ $133M the amount of fraudulent withdrawals estimated by on-chain investigator ZachXBT ($106M on 2 November + $27M the next day), cross-checked by Bitquery (~$108.8M in USDC out in 21h). ⚠️ This figure is NOT confirmed by Crédit Mutuel Arkéa, which discloses no amount and says there is “no financial consequence” for its customers.
