According to the detection of the Beosin EagleEye security warning and monitoring platform, the ULME token project was hacked, causing a loss of 50,646 BUSD. The hacker first used the flash loan to lend BUSD. Since the user authorized the ULME contract earlier, the attacker traversed the authorization of the contract. address, and then transfer the BUSD of authorized users to the contract in batches, increase the price of ULME, and then hackers sell the ULME previously lent by the flash loan, earn BUSD, return the flash loan and leave the market with a profit. The Beosin security team recommends that users cancel BUSD's authorization of the ULME contract and transfer funds in time to reduce losses.
