Suspected EU crypto theft estimate rises to $133M: ZachXBT

What happened

Blockchain investigator ZachXBT raised his estimate of a suspected crypto theft from an unidentified European Union entity to more than $133 million, up from $106 million, after identifying another $27 million in withdrawals from centralized exchanges.

Confirmed

Global impact / market context

If a large Western European financial institution was exploited, the losses and any delayed disclosure could erode trust in how such firms safeguard customer crypto and report incidents, which may push investors to demand clearer disclosure and stronger controls.

Analyst inference

The attacker moved funds into Ether and Monero through instant exchanges and cross-chain bridges, which means swaps that obscure ownership. Large stablecoin conversions can unsettle crypto markets because they reduce the cash-like tokens investors hold and shift value into more volatile assets.

Analyst inference

What to watch

1. Bitquery reported that $62.98 million in stablecoins was converted into 27,553 Ether (ETH) within roughly four hours, showing how quickly stolen funds can be swapped. Confirmed
2. ZachXBT said his working theory is that a large financial institution in Western Europe was exploited and is being covered up, a claim that remains unverified. Proposed
3. If EU law enforcement can freeze fewer remaining funds, only $3.74 million in USDC that issuer Circle could potentially freeze, recovery odds for victims may fall and firms may face pressure to disclose incidents faster. Analyst inference
