Cork Protocol Loses $12 Million in DeFi Hack

Cork Protocol, a decentralized finance (DeFi) platform, recently experienced a significant security breach. Hackers exploited a vulnerability in the platform's smart contract, resulting in the theft of approximately $12 million worth of wrapped staked ether (wstETH).

Cyvers, a blockchain security monitor, was the first to detect the exploit. According to their findings, the malicious contract was deployed by a wallet that appeared to be funded by a service provider. The stolen wstETH was swiftly converted into ETH, highlighting the speed and efficiency of the hackers' operations.

Cork Protocol had previously received investments from notable firms, including a16z crypto and OrangeDAO, in September 2024. This incident underscores the ongoing challenges faced by DeFi platforms in securing their smart contracts against sophisticated attacks.

In response to the incident, Cork Protocol acknowledged the security breach on X, stating that it occurred at 11:23 UTC. The platform promptly paused all other markets as a precautionary measure and initiated an investigation to determine the root cause of the exploit.

Debaub, a security auditing company, provided further insights into the attack. According to their analysis, the attacker likely manipulated an issue with the smart contract's exchange rate by issuing fake tokens. This manipulation allowed the hackers to exploit the vulnerability and siphon off the wstETH.

This incident serves as a stark reminder of the importance of robust security measures in the DeFi ecosystem. As platforms continue to innovate and attract significant investments, ensuring the integrity and security of smart contracts remains a critical priority. The DeFi community will be closely monitoring Cork Protocol's response and the measures they implement to prevent similar incidents in the future.
