Cryptocurrency fraud losses soared to $370.3 million in January 2026, marking the highest monthly total in nearly a year, according to data from CertiK. This figure is nearly four times the losses recorded in January 2025. A significant portion of these losses, approximately $284 million, resulted from a single social engineering attack. In total, 40 security incidents were reported during the month. Uniswap founder Hayden Adams highlighted the ongoing threat of fake search engine ads impersonating Uniswap, which have led to substantial user losses. Scammers purchase keywords like "Uniswap" to promote counterfeit websites that mimic the official site, tricking users into connecting their wallets and authorizing transactions. This method exploits user signature authorization rather than protocol vulnerabilities. A user named "Ika" reported losing hundreds of thousands of dollars after clicking a fraudulent link. The rise in such scams underscores the growing threat of brand impersonation and interface fraud in the expanding DeFi ecosystem.
