U.S. DOJ Arrests Brothers for $25M Crypto Heist in Record Time

In a significant development, the U.S. Department of Justice (DOJ) has apprehended two brothers, Anton and James Pepaire-Bueno, for their alleged involvement in a lightning-fast theft of $25 million worth of crypto. The arrest follows a meticulously planned cyberattack executed via the Ethereum blockchain.

The brothers stand accused of exploiting a vulnerability known as maximal extractable value (MEV), enabling them to siphon funds from unsuspecting users within a mere 12 seconds. These actions have resulted in charges of conspiracy to commit wire fraud and money laundering, marking a critical step in the fight against cybercrime.

Damian Williams, the U.S. Attorney for the Southern District of New York, underscored the sophisticated nature of the brothers’ operation. Williams emphasized their manipulation of Ethereum protocols, essential infrastructure relied upon by millions globally. The brothers’ academic backgrounds in computer science and mathematics allegedly facilitated their ability to tamper with these protocols.


IRS-CI Special Agent in Charge Thomas Fattorusso highlighted the unprecedented nature of the deception, characterizing it as a first-of-its-kind manipulation of the Ethereum blockchain. Through the exploitation of pending transactions, the brothers altered the movement of digital currency, orchestrating the illicit transfer of assets at an alarming pace.

Despite the complexity of the case, law enforcement remains resolute in its commitment to combating financial crimes. Fattorusso affirmed, “Regardless of the complexity of the case, we continue to lead the effort in financial criminal investigations,” signaling the DOJ’s unwavering dedication to ensuring justice in the digital realm.

In a related development, the DOJ has appointed consulting firm Forensic Risk Alliance (FRA) as the watchdog for Binance, a prominent crypto exchange. Tasked with monitoring Binance’s operations for the next three years, FRA will play a pivotal role in enforcing regulatory compliance. This move aims to bolster transparency and accountability within the crypto industry, underscoring the DOJ’s proactive approach to combating illicit activities in the digital financial landscape.
