🔐 Knowledge Analysis | How to Defend Against This "Contract-Level APT"?
✅ Three-Layer Deep Defense Plan
1. Deployment Stage: Process Hardening, Preventing Rush
Standardized Deployment Scripts: Use strictly verified, tamper-proof scripts for agent initialization, eliminating manual operations.
Multi-Signature Initialization: The initialization authority of the agent contract should be executed after confirmation by a multi-signature wallet off-chain, rather than by a single private key.
2. Audit Stage: Beyond Code, Examine Processes
Special Agent Audit: The audit must cover the complete agent upgrade path, initialization authority, and all management functions.
Time Delay Check: Auditors should assume the existence of "sleep logic" and check if any functions can be activated by unauthorized parties in the future.
3. Operation and Maintenance Stage: Continuous Monitoring, Real-Time Alerts
Upgrade Behavior Monitoring: Set real-time alerts for any upgrade-related calls such as upgradeTo for the agent contract.
Permission Change Tracking: Monitor changes to key permissions such as contract owner or DEFAULT_ADMIN_ROLE.
💎 Recommendations for Project Parties
In the face of such attacks, it is essential to establish a "full lifecycle security perspective from deployment to upgrade." The chosen security partner should not only be able to audit code but also provide solutions for your deployment process and operation monitoring.
