.@OnyxDAO was attacked, resulting in a loss of nearly $4M. The root cause was unverified user input during the liquidation process. Specifically, key parameters of the liquidateWithSingleRepay function in the NFTLiquidation contract were controllable by the attacker, allowing manipulation of the extraRepayAmount variable through the repayAmount parameter.

Simultaneously, they created a new contract that, through a donation attack and precision loss (inherent from the Compound V2 fork), reduced the oETH exchange rate, making the attacker's position eligible for liquidation. 2. The attacker then performed the liquidation.

Address poisoning is on BTC now. The following is one concrete case. The phishing address (address 1) is disguising address 2 to send a small amount of BTC to address 3. Since addresses 2 and 3 have historic transactions, the attacker hopes to trick the owner into copying the wrong address.
