The young world of Decentralized Finance (DeFi) is reeling from a major exploit on the UwU Lend protocol discovered on Monday, June 10th. On-chain security firm Cyvers first identified the attack, reporting stolen funds exceeding $14 million. Within an hour, the total haul soared to nearly $20 million.
UwU Lend, a liquidity marketplace that allows users to lend and borrow digital assets, is a vital component of DeFi. This attack, which targeted multiple assets like WBTC (wrapped Bitcoin) and DAI (stablecoin), raises serious concerns about the security of DeFi platforms.
Unfolding a Multi-Million Dollar Exploit
Meir Dolev, CTO and co-founder of Cyvers, describes the incident as a significant crypto hack. “We’re talking about a major incident that has already surpassed the $20 million threshold,” Dolev tells Cointelegraph. The stolen funds originated from various pools within the protocol and were converted to Ethereum.
Cyvers further reveals that the attack, executed through three malicious transactions within six minutes, was financed through the crypto mixing service Tornado Cash. This makes tracing the stolen funds more challenging.

Crypto Hacks on the Rise in 2024
The UwU Lend hack serves as a stark reminder of the vulnerabilities plaguing DeFi. Unfortunately, it’s not an isolated incident. Data suggests crypto hacks are on track to outstrip 2023 in terms of stolen assets. The first quarter of 2024 saw a staggering 42% increase in stolen digital assets compared to the same period last year, with a total value exceeding $542.7 million.
Experts point to two key factors driving this concerning trend. Firstly, the surging value of cryptocurrencies since the beginning of 2024 has made them a more attractive target for malicious actors. Secondly, as Mriganka Pattnaik, CEO of Merkle Science, highlights, hackers are increasingly exploiting areas outside of smart contracts. These areas include private key leaks often caused by phishing attacks or insecure storage practices.
The UwU Lend hack underscores the urgent need for robust security measures within DeFi protocols. As the space matures, developers must prioritize user safety by implementing stricter security audits and educating users on best practices for protecting their digital assets.
