ZachXBT: $133M Drained From Exchange Accounts Belonged to Crédit Mutuel Arkéa

The attribution matters more than the dollar figure: a regulated European bank, not a crypto-native firm, is now the named victim, which puts exchange-account security and bank counterparty exposure in the same frame. The multi-day duration of the attack suggests monitoring and controls failed for longer than a single breach window, and the claim that OTC trades could push losses higher means the disclosed number may not be the final one. The bank's silence leaves the official account unresolved; whether it confirms, disputes or quantifies the loss is the open question.
