Crédit Mutuel Arkéa Confirms Cyberattack After ZachXBT Flags $133M Suspected Losses

The significance here is less the confirmation than the gap between a bank's disclosure and an on-chain investigator's figure: Arkéa validated the order of magnitude but not the number, leaving the precise loss unresolved. That matters for how crypto-native tracing now sets the terms of a traditional bank's incident narrative. The open question is whether the confirmed figure converges toward ZachXBT's estimate or settles elsewhere, and how the bank characterizes the attack's vector.
