Prevention: 3-2-1 Backup Rule
The foundation of ransomware defense:
- 3 copies of data
- 2 different storage types (NAS + external drive)
- 1 offline copy (air-gapped)
Security Basics
- Update all software regularly
- Disable or secure RDP behind VPN
- Use strong admin passwords (12+ characters)
- Enable multi-factor authentication (MFA)
- Train employees on phishing recognition
- Install real-time antivirus
KISIA Free Protection Program
KISA provides free security services to 41 SMEs including vulnerability assessments, ransomware response solutions, and security training. Apply at boho.or.kr.
During an Attack
Never Do
- Pay the ransom — no guarantee; marks you as repeat target
- Keep working on infected PC
- Delete encrypted files
Immediate Actions
- Disconnect from network — unplug LAN, disable Wi-Fi
- Report to KISA 118
- Preserve evidence — screenshot ransom notes
- Verify offline backups
- Contact security professionals
Recovery: No More Ransom
nomoreransom.org offers free decryption tools. Use "Crypto Sheriff" to identify your ransomware. Never delete encrypted files — new decryption tools are regularly added.
Sharing Backup Credentials Safely
SMEs need to share backup admin passwords among team members. Sending via Messenger risks permanent exposure.
Use LOCK.PUB to create password-protected links:
- Write backup credentials as a secure memo
- Set password + expiration time
- Share link with authorized personnel
- Send password via separate channel (phone call)
Auto-deletes after expiration — no sensitive data in chat history.
Summary
| Phase | Key Actions |
|---|---|
| Prevention | 3-2-1 backup, updates, MFA, KISIA |
| During attack | Disconnect, KISA 118, never pay |
| Recovery | nomoreransom.org, restore from backup |
| Credentials | LOCK.PUB for safe sharing |
Prevention is the best defense. Never pay the ransom.
