Summary of the Li.Fi Security Breach
In a recent cyber attack, the DeFi protocol Li.Fi experienced a breach resulting in the theft of around $11 million in Ethereum and stablecoins. The exploit targeted users who had set infinite approvals on their accounts, leaving them vulnerable to unauthorized access. Li.Fi has taken steps to contain the breach and assures users that the system is now secure. This incident reveals a vulnerability in the Li.Fi bridge and is not the first security issue faced by the protocol, which previously lost $600,000 in a 2022 incident.
Li.Fi’s Security Breach
On July 16, 2024, Li.Fi, a cross-chain decentralized finance protocol, fell victim to a significant security breach. Hackers exploited a system vulnerability, resulting in the loss of approximately $11 million in cryptocurrencies. The stolen funds mainly consisted of Ethereum and various stablecoins like USDC, USDT, and DAI. Initially reported at $9 million, Li.Fi later confirmed the total amount stolen was closer to $11 million.
- Cybercriminals targeted Li.Fi protocol, resulting in a loss of roughly $11 million
- Hackers exploited a system vulnerability, gaining unauthorized access to funds
- The stolen funds primarily comprised Ethereum and stablecoins such as USDC, USDT, and DAI
Initial Response and Investigation
Following the breach, Li.Fi swiftly responded by investigating the exploit and advising users to refrain from using Li.Fi-powered applications until further notice. The protocol’s team identified that users who had manually set infinite approvals on their accounts were the focus of the attack. This risky setting allows smart contracts unrestricted access to user funds if compromised.
- Li.Fi immediately initiated an investigation into the security breach
- Users were cautioned against engaging with Li.Fi-powered applications as a precautionary measure
- The exploit targeted users who had granted infinite approvals, granting unchecked access to their funds
Identification of Vulnerability
Security experts traced the exploit back to a vulnerability in the Li.Fi bridge. A newly deployed smart contract function enabled arbitrary calls with user-controlled data, potentially facilitating the breach. Decurity, a crypto security firm, highlighted this issue and linked it to the recent attack.
- A vulnerability within the Li.Fi bridge was identified as the root cause of the breach
- A specific smart contract function allowed for arbitrary calls, aiding in the unauthorized access
- Decurity, a crypto security firm, pointed out the connection between the breach and the newly deployed function
Containment and Next Steps
Li.Fi promptly contained the exploit by disabling the affected smart contract facet. They reassured users that the system was secure and only a small number of those with infinite approvals were impacted. Following the incident, Li.Fi advised users to utilize a secluded revoke website to protect their accounts and provided a list of addresses that needed immediate revocation.
- The exploit was contained by disabling the affected smart contract facet
- Li.Fi assured users of the system’s security and recommended specific actions to protect their accounts
- Users were advised to visit scan.li.fi to check for any compromise on their accounts
Li.Fi’s Ongoing Efforts and Industry Trends
Li.Fi is collaborating with law enforcement and industry security teams to trace the stolen funds and enhance security measures. The protocol acknowledges the need for a detailed post-mortem analysis of the incident. This breach is part of a larger trend, with crypto thefts surging in 2024 compared to the previous year.
- Li.Fi is working with law enforcement and security teams to address the breach
- The protocol plans to conduct a thorough post-mortem analysis of the incident
- Crypto thefts have increased significantly in 2024, highlighting ongoing security challenges in the industry
