The Nirvana Finance hacker pleaded guilty in New York on Thursday.

Shakeeb Ahmed was connected to two hacks — Nirvana and another decentralized exchange. In 2022, DeFi protocol Nirvana was hacked for roughly $3.5 million in a flash loan exploit.

The crypto exchange attacked by Ahmed was left unnamed in the press release announcing his guilty plea. However, when the US Department of Justice first announced the charges against Ahmed, Blockworks reported that the references matched an attack made on Crema Finance in July 2022.

As part of today’s plea, Ahmed forfeited $12.3 million. Nearly $6 million of the sum in crypto. 

The plea marks the first time that the DOJ convicted someone for hacking smart contracts.

“Five months ago, my Office announced the first ever arrest involving an attack on a smart contract. Today, senior security engineer Shakeeb Ahmed pled guilty and agreed to return all of the stolen crypto to his victims,” US attorney Damian Williams said in a press release.

The charges, announced in July, only linked Ahmed to the hacking of a crypto exchange. 

“Ahmed’s plea has also resulted in him further admitting that he carried out a previously unsolved second multi-million-dollar hack, this time of decentralized finance protocol Nirvana Finance.” 

“In the days after the hack of Nirvana, Ahmed conducted internet searches for the term ‘defi hacks prosecution’ and searches related to the charges in the Indictment, including the terms “wire fraud” and “evidence laundering,” the DOJ said.

The DOJ said that Ahmed attacked the exchange in July 2022 by exploiting a smart contract vulnerability. From there, he was able to generate roughly $9 million and withdraw those fees.

“After he stole the fees he never legitimately earned, Ahmed had communications with the Crypto Exchange in which he agreed to return all of the stolen funds except for $1.5 million if the Crypto Exchange agreed not to refer the attack to law enforcement,” the DOJ said. 

Ahmed also took to Google in an attempt to avoid legal action, using the search engine to look up “how to stop federal government from seizing assets” and also tried to research how to buy citizenship. 

Ahmed will pay $5 million in restitution to his victims, and will be sentenced in March 2024.
