What happened
Crédit Mutuel Arkéa confirmed a cyberattack enabling fraudulent transactions, with some transfers suspended and regulators notified. No CVE or initial access vector has been disclosed. ZachXBT's unverified on-chain estimate is over $133 million, including $106 million withdrawn on 1 November, with USDC and USDT converted to Ethereum, bridged across chains and exchanged into Monero. Public reporting links the fraud to subsidiary Fortuneo, which is unconfirmed. Defenders should review payment controls and watch for follow-on phishing impersonating the bank.
