[Mango Markets Attacker Avi Eisenberg's Address Resurfaces with On-Chain Signatures, Sparking Community Attention] Odaily Planet Daily News: Arkham posted on the X platform that Avi Eisenberg, the attacker who profited approximately $110 million in 2022 by manipulating Mango Markets' price oracle, has recently signed transactions from his on-chain address, drawing widespread attention from the community. Avi Eisenberg previously exploited a vulnerability in Mango Finance to conduct 'high-profit trades,' later threatened to attack Aave, and was liquidated on Curve while attempting to liquidate others' positions. Following these incidents, he was arrested and imprisoned. Now that his address has shown on-chain activity again, the market is speculating whether he has returned to the crypto market, though no further details have been disclosed at this time.
