According to Twitter user 3155.eth, some MEV bots have been targeted by hackers. The hackers replaced some of the MEV bots' trading modules, making the sandwich arbitrage impossible. According to Peckshield, the attack has so far caused more than $25 million in losses.
The MEV bot earned from sandwich arbitrage. Sandwich arbitrage, also known as a sandwich attack, is an act that uses preemptive trading to attack a victim's trade orders for arbitrage purposes.
3155.eth also said that the attack may have been a well-planned one, as the hacker had become a validator 18 days ago and prepared the tokens 16 days ago.
