BroadChain, April 28 - According to BeInCrypto, Avraham "Avi" Eisenberg, the trader sentenced for the 2022 Mango Markets attack, has denied threatening to attack Aave (AAVE). Earlier, blockchain analytics platform Arkham reported that an address linked to Eisenberg had re-signed a transaction, suggesting he might return to the crypto market.
Eisenberg insists that his actions in 2022 constituted responsible disclosure rather than an attack threat. He explained that he privately notified the Aave team of potential risks before public disclosure, and the team indicated they were aware and monitoring the situation. The incident stemmed from Eisenberg's attempt to liquidate a large CRV position held by Curve (CRV) founder Michael Egorov, which ultimately backfired, leading to his own liquidation and subsequent imprisonment after pleading guilty in another case.
Additionally, Eisenberg refuted claims made by Chaos Labs founder Omer Goldberg. Goldberg stated in a podcast that Eisenberg had requested Chaos Labs' attack cost model after the Mango incident. Eisenberg explicitly stated that "no such private message ever occurred." Chaos Labs terminated its risk partnership with Aave on April 6.
This controversy once again highlights the blurred security boundaries in the DeFi space: protocol vulnerability probing can be seen as either a threat or a white-hat behavior. Currently, Eisenberg's address has not been blacklisted, and aside from the flagged signature, no new attack activities have been detected.
