News Brief
Based on BlockSec's monitoring from January 27, cybercriminals reportedly exploited a flaw within an unidentified BSC chain contract's "burn pair" function, executing two reverse operations that resulted in approximately $100,000 in losses. Initially, the perpetrators withdrew PGNLZ tokens before activating PGNLP burning. Consequently, they manipulated pricing mechanisms to extract the majority of USDT reserves held within the liquidity pool.

PANews reported on January 27 that, according to BlockSec monitoring, an unknown contract on the BSC chain was exploited. Hackers used a flaw in the "burn pair" mechanism to execute two reverse transactions, ultimately resulting in a loss of approximately $100,000. The attackers first drained PGNLZ, then triggered the burning of PGNLP and price manipulation, thereby stealing most of the USDT from the liquidity pool.
