Crédit Mutuel Arkéa resumes most operations after cyberattack tied to suspected $133M theft

Crédit Mutuel Arkéa says customer funds were unaffected and only certain transfers were delayed, with nearly all operations resuming Wednesday after security checks. Attackers entered via a service provider, not its Fortuneo subsidiary, and moved the bank's own money to other institutions, potentially converting it into crypto. Bitquery traced exchange withdrawals at Kraken, Crypto.com and OKX before the victim was identified. ZachXBT flagged over $106 million Monday, raising his estimate above $133 million after finding another $27 million. Arkéa confirmed only the approximate scale; some funds were frozen and recovery efforts continue. Kraken and Crypto.com restricted linked accounts, saying their platforms stayed secure.
