BlockSec Phalcon said on social media that the system has detected hundreds of suspicious transactions against an unknown and unopen-sourced contract (0xff2481) on BSC in the past few hours, indicating a possible reentry attack. Total losses have now reached about $140,000.
After the first attack, which resulted in a profit of approximately $78,000, the deployer (0x7baa94) repeatedly invoked the victim contract's "emergencyWithdrawUSDT" function, withdrawing only a small amount of funds each time, rather than withdrawing all of them at once. This allowed the attacker to make small profits multiple times, eventually accumulating losses of $140,000.
