Introduction
Ransomware encrypts your data and demands payment for the decryption key. SMBs are targeted because they often have weaker defenses and are more likely to pay. Prevention and preparation are essential.
How Ransomware Gets In
Common entry points include phishing emails, unpatched software, weak passwords, and exposed remote access. Attackers exploit these to gain access and then deploy ransomware across your network.
Prevention Basics
- Enable multi-factor authentication everywhere possible.
- Keep systems patched and updated.
- Train employees on phishing awareness.
- Restrict admin access and use least-privilege principles.
- Segment your network to limit lateral movement.
Backup: Your Last Line of Defense
If ransomware encrypts your data, the only reliable recovery is from backups. Ensure backups are isolated from your live network (offline or immutable), tested regularly, and retain multiple versions. Many attackers now target backups, so isolation is critical.
If You're Attacked
Don't pay immediately. Isolate affected systems, preserve evidence, and contact law enforcement and a cybersecurity firm. Evaluate whether restoration from backups is feasible. Payment doesn't guarantee decryption and may fund further attacks.
