Exploit radar: LCX Hot Wallet Hack

LCX, a Liechtenstein-based exchange announced late on January 8th that it had suffered a hack to one of its hot wallets. In an announcement released by LCX, the stolen funds were reportedly drained from this LCX hot wallet and transferred to a single address controlled by unknown hacker(s).

The hacker(s) struck January 8, 2022, swiping funds from LCX at 10:23 pm GMT. In under an hour, the hackers swept out LCX, USDC, SAND, LINK, QNT, ENJ, ETH, and MKR. The hackers then moved to convert stolen assets to ETH utilizing several popular DeFi services. For example, the $3.4+ million USDC stolen in the hack was converted to native ETH within 16 minutes. In total, all stolen funds were converted within 45 minutes of the first outbound transfer.

By 11:12 pm GMT, the hackers swiftly moved converted ETH to Tornado.Cash, a mixing service often used to anonymize stolen assets on the Ethereum blockchain. Interestingly, the hackers used the 100, 10, and 1 ETH contracts on Tornado, a move that was not necessarily required arithmetically. In total, the operation from theft to deposit at Tornado was complete within 1.5 hours of the initial hack, earning the hackers roughly $5.33 million per hour. TRM will continue to monitor the flow of funds to support fund recovery efforts where relevant.
