A victim lost 783 Bitcoin (about $USD1 91.4 million) in a social engineering attack on Tuesday, according to blockchain investigator ZachXBT.

The attackers posed as customer support representatives for a hardware wallet maker and a crypto exchange, tricking the victim into authorizing the transfer at 11:06 am UTC. A day later, the attackers began laundering the funds through the privacy-focused Bitcoin mixer Wasabi Wallet to conceal the trail.

More than $USDC 2.1 billion was stolen in crypto-related attacks in the first five months of 2025, according to blockchain security firm CertiK. Investors are reminded to always be cautious when receiving messages and to verify their authenticity.
