Li.Fi Protocol Hack Results in $9 Million Crypto Loss: A DeFi Security Breach

Li.Fi Protocol Hack Results in $9 Million Crypto Loss: A DeFi Security Breach

In a recent unsettling development in the DeFi space, the Li.Fi Protocol Hack targeted the cross-chain DeFi protocol, resulting in the loss of nearly $9 million in cryptocurrencies. Blockchain security firm CertiK reported this incident, noting that a wallet linked to the hack contained $8.7 million in digital assets, including almost $6 million in Ethereum (ETH) and various stablecoins such as USDC, USDT, and DAI.

Details of the Li.Fi Exploit

The exploit targeted Li.Fi users who had manually adjusted their account settings, specifically those who set infinite approvals. The Li.Fi team disclosed this vulnerability in a recent post on X (formerly known as Twitter), urging users who had not set infinite approvals to rest assured that their assets were not at risk. Despite the assurances, the situation has raised concerns about the ongoing security risks in the DeFi sector.

Following the detection of the exploit, Li.Fi acted swiftly to mitigate any further risk to its users. The protocol has since disabled the affected smart contract facet and confirmed that the exploit has been contained. However, the incident has only affected a small number of users who opted for infinite approvals, highlighting the need for cautious security practices in digital asset management.

Immediate Steps for Users

In response to the exploit, Li.Fi has taken proactive steps to safeguard its users’ interests. The protocol urged affected users to immediately use their dedicated revoke website to withdraw permissions. Additionally, Li.Fi has set up a facility for users to check if their accounts have been compromised through their scanning tool at scan.li.fi.

Underlying Causes and Previous Incidents

According to crypto security firm Decurity, a vulnerability in the Li.Fi bridge, involving an arbitrary call with user-controlled data via the depositToGasZipERC20() function in the GasZipFacet, likely caused the Li.Fi Protocol Hack. Li.Fi deployed this function just five days before the incident. This is not the first time Li.Fi has faced security challenges; in 2022, a bug in the protocolโ€™s swapping feature led to a loss of $600,000 in crypto, as detailed in a post-mortem analysis shared by Li.Fi on Medium.

The recurring security breaches in Li.Fi’s operations underscore the critical importance of robust security measures and constant vigilance in the rapidly evolving DeFi landscape. As the sector continues to grow, the need for enhanced protective mechanisms becomes increasingly paramount to prevent such exploits and safeguard user assets.
