After the theft, the victim sent an on-chain message to the scammer, offering a $1 million "bounty" for the return of the remaining funds. They threatened, "We have officially filed a criminal case. With the assistance of law enforcement, cybersecurity agencies, and multiple blockchain protocols, we have already gathered substantial and actionable intelligence regarding your activities." However, there's been no activity from the wallet since the message, and the thief had long since begun laundering the funds via Tornado Cash.
Crypto trader loses $50 million to address poisoning attack
A crypto trader lost almost $50 million in the Tether stablecoin after falling victim to an address poisoning attack. Because blockchain wallet addresses are long, random alphanumeric strings, traders often use the first and/or last several characters to quickly recognize wallets, and copy and paste regularly used wallet addresses from their transaction history. This has given rise to a type of scam known as "address poisoning", where scammers generate wallet addresses that share similar beginning and end characters, and use them to send transactions to wealthy victims. If they're lucky, as they were in this case, the victim will accidentally copy the similar looking scammer's wallet address when making a transfer of significant size.
