Eradication removes the attacker from your environment. Recovery restores operations with confidence the threat is gone.
Eradication:
- Remove malware from all affected systems
- Close attacker backdoors
- Reset compromised credentials
- Patch exploited vulnerabilities
Recovery:
- Restore from clean backups
- Rebuild compromised servers
- Verify integrity before reconnecting
- Monitor for re-infection
Common mistakes: Recovering too quickly, missing persistence mechanisms, restoring from compromised backups, failing to verify systems.
