A federal jury in Manhattan began hearings today for the two MIT-educated brothers who were accused of planning and executing a $25 million heist from the Ethereum blockchain. The U.S. Department of Justice described the case as ‘first of its kind’ due to the complex nature of the scam.
The two brothers, Anton Peraire-Bueno, 25, and James Peraire-Bueno, 29, are facing conspiracy, wire fraud, and money laundering charges for allegedly exploiting the Ethereum blockchain’s transaction validation process in 2023. According to the prosecutors, the brothers used their advanced technical skills in the blockchain network to manipulate pending trades on the network. The brothers took away $25 million in Ethereum tokens in just 12 seconds.
Ethereum ‘Exploit’ case puts blockchain integrity under legal scrutiny
According to a release by the U.S. Department of Justice, the Peraire-Bueno brothers, who studied computer science and mathematics at the Massachusetts Institute of Technology, allegedly used their special skills in blockchain technology to compromise the integrity of the Ethereum blockchain. The two brothers have pleaded not guilty and are currently free on a $250,000 bail each.
The trial sought an educated Jury panel, half of which holds a master’s degree in several areas of study, including finance and medicine. U.S. District Judge Jessica G. L. Clarke led the first trial. The education levels of the selected Jury reflect the complex technical nature of the case that they will have to evaluate. Prosecutors in the case will have to provide evidence showing that the two brothers studied the trading patterns of their victims before carrying out the code-based attack, which involved intercepting and rerouting pending Ethereum transactions.
“Unfortunately for the defendants, their alleged crimes were no match for DOJ prosecutors and IRS agents, who unraveled this first-of-its-kind wire fraud and money laundering scheme,”
–Lisa Monaco, Deputy Attorney General
The court filings revealed that the operation dubbed ‘the Exploit’ was meticulously planned over several months and carried out in seconds. They added that the two brothers analyzed blockchain data for several months, created shell companies, and created multiple wallets with foreign exchange accounts to conceal the proceeds.
Prosecutors of the Exploit revealed that before and after the April 2023 incident, the two brothers conducted online searches for ‘how to wash crypto’, ‘fraudulent Ethereum addresses database’, and ‘money laundering statute of limitations’. They added that once the funds had been stolen, the two accused washed them through a network of transactions to hide the original wallet.
Prosecutors say ‘Exploit’ case is key to safeguarding blockchain integrity
Damian Williams, the U.S. Attorney for the Southern District of New York, described the alleged scheme as novel and has never been charged before. He acknowledged that, regardless of the sophisticated nature of the case, the Justice system will relentlessly pursue those who attack the financial system’s integrity.
The defense attorneys argued that the prosecution mischaracterized the nature of the alleged attack. They stated that the brothers simply exploited flaws in the blockchain network. They added that the accused only exploited the predatory nature of automated trading bots in the decentralized ecosystem. The defense also argued that there were no direct interactions between the defendants and the alleged victims.
Following the defense attorneys’ remarks, Judge Clarke barred them from making their claim based on the notion that the victims deserved the losses or from introducing expert testimony on the lack of crypto regulation. The move to bar the defense has created a setback for the defense’s legal strategy amid the trial, which is expected to continue into early November.
If convicted, Anton and James Peraire-Bueno face up to 20 years in prison on each count. Prosecutors insist that safeguarding the integrity of the Ethereum blockchain is essential to maintaining investor confidence in decentralized ecosystems.
Cryptopolitan reported last month on another sophisticated crime in which hackers hid malware inside Ethereum smart contracts. ReversingLabs’ research uncovered a malware campaign that used Ethereum smart contracts to conceal malicious software URLs. The findings revealed that the hackers used the npm packages colortoolv2 and mimelib2, which acted as downloaders.
