TechFlow news — Cobo's blockchain security team recently conducted an analysis and reproduction of the Optimism theft incident, providing a comprehensive technical breakdown from multiple angles including timeline, attack vector, Ethereum contract address generation, and technical details.
Meanwhile, Cobo’s blockchain security team reminds users that when handling different network layers, operations involving contracts should be approached with caution. It is essential to first verify whether the contract addresses, content, and status on the target network match those on the Ethereum mainnet. In cases involving complex logic, compatibility between the target network’s characteristics and the contract functionality should also be verified. One should not assume that Layer 1 addresses will map seamlessly to Layer 2 or sidechains, in order to prevent recurring blunders like the Wintermute incident.
Members of Cobo's blockchain security team come from renowned security labs, with years of experience in cybersecurity and vulnerability research. They have assisted Google and Microsoft in resolving critical vulnerabilities and have been acknowledged by vendors including Google and Microsoft. The team has also achieved outstanding rankings in Microsoft’s MSRC Most Valuable Security Researcher program. Currently, the team focuses on smart contract security and DeFi security, actively researching and sharing cutting-edge blockchain security technologies.
