Wallet targeted by CPIMP frontrun attack on BSC; attacker exploited transaction ordering to steal funds.
Security & Exploits ·
A wallet on Binance Smart Chain fell victim to a frontrunning attack exploiting transaction ordering, according to an onchain alert. The attack, identified as "CPIMP," targeted a victim proxy contract while an attacker address executed a malicious transaction ahead of the user's own, allowing funds to be stolen before the legitimate transaction could complete.
Frontrunning attacks work by observing pending transactions in the mempool and inserting a competing transaction with higher gas fees to execute first, thereby manipulating the order of execution. In this case, the attacker manipulated the sequence to extract value from the victim's transaction on BSC.
The specific attacker address and attack transaction have been identified onchain, but details about the total funds stolen, the underlying protocol or token involved, and whether recovery efforts are underway remain unclear from available information.
