## Summary

A cyberattack on Crédit Mutuel Arkéa has prompted concern across European banking, after hackers took more than €100 million from the French bank’s own funds. Experts described the incident as unprecedented in scale for a European bank and said it exposed vulnerabilities despite the sector’s strict regulation and frequent security audits.

The attackers compromised a third party authorised to make transactions, accessed Arkéa’s capital and moved the money into cryptocurrency across several exchanges. The bank held about €10 billion; the theft was roughly equivalent to a quarter’s annual net profit, though no customers lost money. The precise total and those responsible remain unclear, and experts questioned why safeguards against large transfers did not stop the operation.
