**Deck**: French banking group Crédit Mutuel Arkéa has confirmed a cyberattack that enabled fraudulent transactions, with blockchain investigators estimating more than $133 million stolen in crypto assets, while the bank says the breach is contained and customer assets are unaffected.

French banking group Crédit Mutuel Arkéa has confirmed it was hit by a cyberattack that enabled fraudulent transactions linked to a theft of more than $133 million in crypto assets traced on public blockchains.

Investigators following the stolen funds on-chain estimate losses exceeding $133 million. The assets were moved through several cryptocurrencies, including USDC, USDT, Ethereum, and Monero.

Crédit Mutuel Arkéa says the breach is contained and that customer assets remain unaffected. The bank has not publicly detailed how attackers gained access or which internal systems were compromised.

The use of liquid tokens such as USDC, USDT, and Ethereum suggests the attackers were able to quickly move value into widely traded assets. The reported flow into Monero, a privacy-focused cryptocurrency, points to an effort to make further tracking and potential recovery of the funds more difficult.

For the bank, the incident raises operational and reputational risks around its exposure to digital assets and the security of any systems connected to blockchain-based transactions, even as it seeks to reassure clients that their funds are safe.

Signals to watch next include any technical explanation from Crédit Mutuel Arkéa about how the attack unfolded, steps it is taking to strengthen defenses, and whether law enforcement or regulators in France and the EU provide updates on attempts to freeze or recover the stolen crypto.
