Is This the Trader Who Exploited Mango Markets for $100M?

One sleuth believes he is aware of the id of the particular person answerable for Mango Markets’ $100 million assault, however how dependable is his proof?

Mango Markets Exploited

Crypto dealer Avraham Eisenberg allegedly mentioned exploiting a protocol on a Discord server for a nine-figure loot. Six days later, Mango Markets was drained of $100 million. 

In accordance with unbiased investigative reporter Chris Brunet, Mango Markets was drained of its funds yesterday by crypto dealer Avraham Eisenberg. Brunet claims Eisenberg had beforehand talked in a personal discord server about the opportunity of attacking a protocol in an analogous strategy to how Mango Markets was exploited.

Mango Markets is a decentralized derivatives change on Solana. On October 11, at round 22:19 UTC, an attacker started artificially inflating the worth of the illiquid MNGO token from $0.3 to $0.91 by taking out a big place in Mango’s perpetual futures contracts. They then used their vital unrealised earnings as collateral to borrow property belonging to the protocol, draining over $100 million from its treasury.

Discord Dialogue

In his article, Brunet claims Eisenberg floated the concept of attacking a lending protocol on Discord on October 5. “I’m investigating a platform that might perhaps result in a 9 determine payday,” Eisenberg allegedly wrote below his pseudonym, Vires Creditor and Sincere Particular person. When one other Discord member recommended sharing the data with well-known crypto white hat hacker samczsun, Eisenberg responded that the protocol’s Treasury was small and that he almost certainly wouldn’t get a big bounty if he publicized the assault vector.

He then defined the assault itself: “You are taking a protracted place. And you then make [the price] go up. And you then withdraw all of the protocol’s [total locked value].” When one other Discord member explicitly stated it might be theft, Eisenberg replied he thought-about it as an act of arbitrage, that means a commerce that goals to reap the benefits of differing costs for sure property.

Eisenberg additional acknowledged that Ethereum lending protocol Aave could possibly be exploited this fashion, although the assault would require no less than $10 million upfront to work. Eisenberg referred to as that specific exploit “extra annoying than what I bear in mind.”

Brunet supplied screenshots of the dialog on his Substack web page. When contacted by Crypto Briefing, Brunet claimed the dialog had been deleted from the Discord server by the channel’s moderators out of panic. Crypto Briefing has, subsequently, not been capable of confirm the authenticity of those screenshots independently. Nevertheless, if they’re correct, it might imply that Eisenberg was discussing an exploit remarkably just like the one which shook Mango Markets six days earlier than it occurred. 

On-Chain Exercise

Brunet supplied a screenshot of Eisenberg offering on June 4 an ENS identify for one in every of his Ethereum addresses: ponzishorter.eth. That ENS identify is linked to an account that begins with 0xADBaB, which is the account that registered the identify within the first place.

As Brunet identified, ponzishorter.eth received precisely $7,500,000 in USDC straight from Circle at 23:28:35 UTC. Brunet discovered the transaction suspicious because the Mango attacker had sent $7,519,769,12 to Circle from Solana at 23:27:07 UTC, that means the 2 transactions had been despatched off inside a minute and twenty-eight seconds from one another.

Crypto Briefing subsequently discovered two extra transfers that had been eerily timed. The attacker first sent Circle $5,000,000 in USDC at 23:14:54, and the ponzishorter.eth pockets received $4,500,000 in USDC at 23:16:35, about one minute and thirty-nine seconds later. The attacker then sent a further $20,000,000 in USDC to Circle at 23:17:38; a minute and 9 seconds later, at 23:18:47, ponzishorter.eth received $18,000,000 in USDC. 

Whereas the ponzishorter.eth pockets persistently obtained decrease sums than those despatched to Circle by the attacker, the timing across the transactions warrants suspicion.

Intriguingly, the ponzishorter.eth proprietor additionally selected to instantly swap his $30 million in USDC for DAI. Circle has been identified to blacklist and freeze the USDC in addresses belonging to hackers. It’s potential the ponzishorter.eth proprietor purposefully traded his tokens for decentralized stablecoins with a view to keep away from this.

It’s price noting that the Mango attacker sent a further $25 million to Circle at across the similar time. The transaction was not mirrored on the ponzishorter.eth, which signifies the attacker might have no less than one different pockets, or that they stored the funds on their Circle account (which is unlikely.)

When reached for remark, a spokesperson for Circle advised Crypto Briefing, “Circle is investigating the incident in query and can take acceptable motion.”

Up to now, the hyperlink between ponzishorter.eth and Eisenberg is contingent on the screenshot supplied by Brunet, and there’s no conclusive proof that he’s the wrongdoer on this case. It’s not the primary time Eisenberg has confronted comparable allegations, nonetheless. In February, he was accused on Twitter of exploiting Fortress DAO for $10 million.

Crypto Briefing has reached out to Eisenberg for remark however had not obtained a reply at press time.
