French bank Crédit Mutuel Arkéa exploited for over $133 million, ZachXBT says

What happened

Onchain investigator ZachXBT says French cooperative bank Crédit Mutuel Arkéa was allegedly exploited for over $133 million. He traced more than $106 million in withdrawals from multiple centralized exchange accounts, then added another $27 million; some withdrawals reportedly followed his initial disclosure. The bank has not commented in the supplied article.

Confirmed

Global impact / market context

If the reported theft is confirmed, losses could reduce the bank’s available cash or require it to absorb costs, while any larger final tally could increase that burden. The reported movement of stolen funds through cryptocurrencies may also complicate recovery, though the article does not establish the bank’s net loss.

Analyst inference

The article describes withdrawals in USDC and USDT, stablecoins designed to track the US dollar, followed by swaps into ETH and transfers toward XMR, a privacy-focused cryptocurrency. This traces the alleged funds’ path, but provides no evidence of market-price effects or broader industry exposure.

Confirmed

What to watch

1. Watch for a statement from Crédit Mutuel Arkéa confirming or disputing the allegation and explaining whether the reported withdrawals affected customer accounts or the bank’s own funds. Analyst inference
2. Further tracing could clarify the final amount, including whether over-the-counter trades, meaning direct transactions between parties, added losses beyond those already identified. Analyst inference
3. The article says some withdrawals occurred after ZachXBT’s initial disclosure; subsequent reporting on when funds moved could clarify whether the disclosure changed the attacker’s activity. Confirmed
