Security & Exploits ·
A wallet on the Binance Smart Chain was targeted by a frontrunning attack identified as "CPIMP," according to an onchain alert. The attacker, operating from address 0x3dA435fc3331b87B68576334367D017F95247aeC, exploited transaction ordering to intercept and execute trades ahead of the victim's transaction, resulting in fund theft. The victim's proxy contract was identified as 0xeb899878BA1B35e0760D5dbE59989356cAB30B5b.
Frontrunning attacks work by inserting transactions into the mempool ahead of pending user transactions, allowing attackers to profit from predictable price movements or steal tokens before legitimate trades settle. On BSC, where block times are short and mempool visibility is relatively high, such attacks remain a recurring vulnerability for users trading through smart contracts or liquidity pools.
The alert warns users not to reuse the targeted contract, though the broader scope of the attack—whether it affected only this single wallet or multiple users of the same contract—remains unclear from available information.
