The 91 million Bitcoin heist refers to the theft of 783 BTC (approximately $91 million) from a private holder on August 19, 2025, executed through social engineering. Attackers impersonated wallet support, gained access to keys or approval flows, and immediately laundered funds via Wasabi Wallet to frustrate tracing.
Attackers used impersonation tactics to convince the victim to reveal credentials or perform an action that transferred funds. After extraction, funds were sent through Wasabi Wallet, a privacy-focused CoinJoin service, which mixed the BTC and increased on-chain analysis difficulty.
Blockchain investigator ZachXBT publicly tracked the initial movements and noted rapid CoinJoin usage. No centralized exchange withdrawals or known exchange accounts were implicated during the initial tracing window.
