Trust Wallet issued a security alert on December 26 confirming a vulnerability in its browser extension version 2.68, with on-chain analyst ZachXBT reporting that hundreds of users have lost at least $6 million. The wallet previously faced a WebAssembly flaw affecting new addresses created between November 14 and 23, 2022, resulting in about $170,000 in losses that were later fully reimbursed through a bug bounty process.
