French bank confirms cyber heist, hackers suspected to have stolen an estimated $133 million
Crédit Mutuel Arkéa has confirmed a cyberattack in which hackers allegedly stole around $133 million by compromising a third-party supplier and using the bank's own accounts to execute fraudulent transfers.
Why this matters: The attack did not go through the front door. Hackers got in through a supplier, then used the bank's own systems to move the money. That is the supply chain problem in plain sight. Banks trust vendors with deep access, and when one vendor fails, the attacker is suddenly inside. Customers did not cause this. They had no way to prevent it. The question is what scrutiny the bank applied to that supplier before handing over access worth nine figures.
