Summary

On June 5, the DTXT/USDT trading pair on BSC suffered a major exploit, resulting in the loss of approximately 35,041 USDT. Attackers exploited a contract vulnerability by sending a small amount of USDT directly to the trading pair address, bypassing sell fees. The theft was facilitated by a 1,077,400 USDT flash loan from Moolah. The incident underscores a significant decline in trading activity and has raised concerns about smart contract security on high-volume trading pairs.

BlockBeats report, June 5: According to SlowMist monitoring, the DTXT/USDT trading pair on BNB Chain was attacked, resulting in a loss of approximately 35,041 USDT. The root cause of the attack was that the DTXT contract determined transaction types by comparing USDT balances with the trading pair’s reserve amounts. The attacker directly transferred a small amount of USDT to the trading pair address, causing a large DTXT sell order to be incorrectly classified as adding liquidity, thereby bypassing the sell fee logic.

The attacker borrowed 1.0774 million USDT via a flash loan from Moolah and profited approximately 35,000 USDT.
