🚨 Real Case Analysis | Cross-Chain Protocol Governed Attack, Loss Exceeds $130 Million
💸 Event Review
Last year, a well-known cross-chain protocol was attacked due to a governance mechanism vulnerability, resulting in a loss exceeding $130 million. The attacker borrowed a large amount of governance tokens through a flash loan and completed the entire attack process from proposal to execution in a single transaction.
🔍 Vulnerability Analysis
Governance Mechanism Flaw: Proposal execution lacked time lock protection
Voting Weight Imbalance: Instant token holding amount determines voting power
Economic Model Flaw: Lack of protection against flash loan attacks
Monitoring System Failure: Abnormal governance activities did not trigger alarms
📊 Impact of the Attack
Protocol TVL plummeted by 68%
Governance token price plunged by 45%
Triggered a chain reaction in the cross-chain ecosystem
🛡️ Protection Measures
✅ Set a 48-hour time lock for governance proposals
✅ Implement time-weighted voting mechanism
✅ Establish flash loan attack detection system
✅ Deploy real-time monitoring of governance activities
💡 Key Insight
"Governance attacks are becoming a new threat in the DeFi space; protocol security needs to extend from the code layer to the governance layer."

🚨 Case Analysis | Cross-Chain Bridge Governance Attack: In-Depth Analysis of $1.3 Million Loss at Stargate Finance
Incident Review
Last year, the cross-chain bridge Stargate Finance, based on LayerZero, was attacked due to a governance mechanism vulnerability, resulting in a loss of approximately $1.3 million. The attacker borrowed a large amount of governance tokens STG through a flash loan and completed the entire attack process from proposal to execution within a single block.
Attack Technique Breakdown
Governance Power Monopoly: Instantaneously acquire over 51% of voting power through flash loans
Malicious Proposal: Submit a malicious governance proposal to transfer protocol funds
Rapid Execution: Exploit the time vulnerability in the governance mechanism to complete voting and execution within the same block
Fund Transfer: Transfer protocol funds to an address controlled by the attacker
Key Findings from Security Audit
71% of DeFi protocol governance mechanisms have similar time vulnerabilities
The single block governance attack used in this attack is a new type of composite attack model
Projects that have undergone dedicated governance security audits have a 87% lower probability of encountering such attacks
Protection Scheme Upgrades
✅ Governance proposals must set a voting period of at least 24 hours
✅ Key fund operations must introduce a time-lock delay mechanism
✅ Conduct specialized stress testing for flash loan governance attacks
✅ Establish a real-time monitoring and early warning system for governance activities
Core Insight
"The excessive concentration of governance power and the overly rapid execution are becoming new attack vectors. The security of cross-chain bridges should not only focus on technical implementation but also pay attention to the security of governance mechanism design."
