What happened
On January 19, 2023, Thoreum Finance on BSC was exploited through a logic flaw in the transfer mechanism. An attacker deposited BNB to gain WBNB, then used the swapExactTokensForTokensSupportingFeeOnTransferTokens function to exchange for THOREUM tokens, exploiting a branch in the transfer logic to profit approximately 2,260 BNB (~$65.5K).
In review: sources disagree on the loss.
