According to on-chain security analyst Scam Sniffer (@realScamSniffer), about 7 hours ago, a user transferred $103,100 to a fraudulent address by copying the wrong address from the tainted transfer history. Another user lost $43,674 in the same way about 14 hours ago. It is reported that the "transaction history contamination attack" involves fraudsters sending fake transfers with similar addresses, so that the fake address appears in the user's transaction history, and the user mistakenly copies the address when transferring money again.
