69-year-old U.S. individual loses 3,520 BTC ($330.7 million) through social engineering theft and Monero laundering spree

Summary

A 69-year-old U.S. individual lost 3,520 BTC ($330.7 million) in what on-chain investigator ZachXBT identified as a social engineering theft. The stolen Bitcoin was rapidly moved in small increments and laundered through more than six instant exchanges, where it was swapped for Monero (XMR). This activity caused the price of Monero to spike by 50%, reaching a high of $329 before correcting to $267. The theft involved unusually high transaction fees, with some atomic swaps costing 1-3% of the exchange amount. Other privacy-focused cryptocurrencies like ZCash and Dash also saw price increases during the same period.
