What Auditors Should Check
If you're auditing a protocol with similar architecture to Phishing, these are the critical security checks that could have prevented this incident (August 2025).
- Verify all logic paths related to Phishing are guarded by proper access controls and input validation - see the Phishing Attacks attack class for patterns
- Review privileged functions (owner, admin, governance) for potential abuse vectors - centralization risks should be documented and bounded with timelocks or multi-sigs
