What happened
Crédit Mutuel Arkéa, a French regional bank with 5.8 million customers, disclosed a supply chain intrusion in which attackers accessed an internal account through an unnamed third-party service provider's platform and moved funds to other financial institutions. Funds may have been converted to cryptocurrency. Le Télégramme reported losses above €118 million, which the bank did not confirm. Some funds are frozen and recovery is under way, and French law enforcement is investigating. No CVE or technical indicators were published. Defenders should review third-party platform access to internal accounts and outbound transfer controls.
