A months long, premeditated attack exploiting a known, dismissed vulnerability in a low liquidity token market. Mefai Analysis. We investigated after seeing some articles suggesting that @Binance was to blame. It has nothing to do with Binance,(We know this was intentional.) and #Venus has also warned team about this. Venus Protocol vTHE Attack | Full Analysis Attacker, 0x1a35bd28efd46cfc46c2136f878777d69ae16231 Funding: 7,400 ETH from Tornado Cash The Block How It Worked, Attacker spent 9 months (starting June 2025) quietly accumulating ~84% of THE's supply cap (14.5M tokens). Then, instead of depositing normally, they transferred tokens directly to the vTHE contract a donation attack bypassing the supply cap entirely and building a 53.2M THE position, 3.7× the allowed limit. They then ran a classic loop, 1 deposit THE 2 borrow assets 3 buy more THE 4 wait for TWAP oracle update 5 repeat, pushing THE's price from ~$0.263 to ~$0.563 before it collapsed to ~$0.22 on liquidation. Assets borrowed, 6.67M CAKE, 1.58M USDC, 2,801 BNB, and 20 BTC. Damage , ~$2.15M in bad debt remained 1.18M CAKE and 1.84M THE unrecoverable.
