On November 22, the community discovered that a giant whale was trying to short Curve (CRV). The address shown as ponzishorter.eth borrowed a large amount of CRV through Aave mortgage for selling, and sold both on-chain and off-chain. It successfully dropped the price of CRV all the way from $0.6 to around $0.4. According to statistics, this address has sold about 5% of the circulating supply of CRV.
However, the Curve team quickly responded that due to the clear position price, it directly pulled CRV to the giant whale In the end, the giant whale liquidated the liquidation price, leaving a bad debt of 1.6 million US dollars in Aave.
This is not the first time that the address of ponzishorter appeared in everyone's sight. The initiator of the attack was also this address, which not only cost Mango $100 million, but also stunned the community through the DAO attack. Subsequently, ponzishorter also tried to short USDT, but it has not been successful.
"The giant whale emerged from the water. Who is Eisenberg? BlockBeats compiled an article about him from protos as follows:Disclosure by independent investigator Chris Brunet revealed (less than 24 hours after the attack) that he was behind one of October's biggest losses (the over $100 million manipulation at Mango Markets), in a post accusing Avraham Eisenberg (a self-proclaimed "digital art dealer") of article, which includes a screenshot of a Discord conversation - account Avraham Eisenberg#5541 discussing details of the days leading up to the attack.
When another user prompted him to disclose the vulnerability, he declined because he thought the Projects have too little funding to pay large bug bounties. In fact, after the attack, the hackers used the newly stolen funds to create and vote on a governance proposal that would reward them with a bounty of more than half of the hacked amount.
Eisenberg's response to the screenshot was also published in the same article, claiming that he was "being Explore some lending platforms for tokens with low market value”, but did not specifically mention Mango Markets.
This is not the first time Eisenberg has been accused of DeFi violations
In February of this year, he was accused of misappropriating $14 million from Fortress DAO (a project he was responsible for developing) . Eisenberg allegedly abused the project’s fund redemption mechanism to reallocate remaining funds to token holders when Fortress DAO ceased operations; in April, an address associated with a ponzishorter.eth account was used to manipulate the lending protocol Fuse's liquidation mechanism.
However, as Kleros founder Clment Lesaege Said, Eisenberg tried to use "to Centralized Arbitration Protocols have not always had such smooth sailing through the claims process.
Not only was Eisenberg content with blockchain-based disputes, he even sued a small New York state town after one failed operation. He may be a professional market manipulator, but no one seems to be able to escape his clutches.
Law enforcement is always beyond the reach
On-chain sleuthing is often a thankless task, and the sheer amount of shady activity associated with cryptocurrencies, NFTs and DeFi means that disclosures are often swift submerged.
There is nothing stopping scammers from setting up a new on-chain address and Twitter profile, starting over with a pseudonym . The technical knowledge necessary for law enforcement to take a claim seriously could also hinder bringing those responsible to justice, with some exceptions, and ZachXBT, a prominent "on-chain detective," has previously said that after his August revelations, a pair of French Crypto phishing scammers charged.
In Eisenberg's case, especially for someone who is clearly an encryption expert, These oversights are simple in comparison, and he seems to agree with the common belief among hackers - "code is law", but in the face of on-chain evidence and FTX's claim that it is investigating Mango Markets, he may soon have the opportunity to test in court own beliefs.
After the October 13 Japanese release, Eisenberg has contacted Protos to resolve concerns about Mango Markets allegations and comments from Kleros founder Clment Lesaege.
About Mango Markets, Eisenberg tweeted a Detailed statement:

Responding to Lesaege's comments, he stated:
"This year In February, Fortress DAO voted for a full treasury redemption, a plan I helped implement, and by the end of March, the redemption plan had been completed and any Fort token holder could withdraw and receive a proportional share of the funds.”< /p>
"Clment Lesaeg launched a 51% attack on his own Kleros, he invested millions of dollars in the Unslashed insurance pool, and then in When claiming, he used a large number of PNK tokens he held to reject millions of dollars in legal claims and pocketed them. I published an article on the Deep Fi Value blog called "The Kleros Experiment Failed" , documenting this fraud in detail. "
