A joint effort between US law enforcement agencies has led to the seizure of $31 million in cryptocurrency linked to the April 2021 attack on Uranium Finance.

According to a February 24 post on X, the US Attorney’s Office for the Southern District of New York and Homeland Security Investigations in San Diego confirmed the recovery but did not disclose any details about the individuals responsible.

Uranium Finance, a decentralized finance (DeFi) platform built on the BNB Chain, went live in early April 2021 using Uniswap’s UNI $5.91 automated market maker model. However, the platform became the target of a security breach within weeks.

On April 28, 2021, the project’s website was taken offline, and its social media accounts went silent, leaving affected users without any guidance on retrieving their funds.

Security flaws in Uranium Finance’s second version of its smart contracts were exploited in the attack, allowing the hacker to manipulate the system and inflate token balances 100 times.

This loophole enabled them to drain approximately $50 million worth of crypto, including around $36.8 million in BNB BNB $860.51 and Binance USD BUSD $0.9998 at the time.

Concerns about an internal breach surfaced at the time, with a Discord administrator suggesting the attack may have been orchestrated from within the project.

Meanwhile, Infini, a stablecoin payment platform, suffered a $50 million security breach. How? Read the full story.
