The anatomy of a Ransomware Attack
Ransomware attacks have evolved from simple desktop encryption to coordinated network intrusions. Attackers locate corporate backup systems, disable security agents, exfiltrate sensitive data (double extortion), and encrypt primary filesystems, demanding millions in cryptocurrency for the decryption key.
The 3-2-1-1-0 Backup Rule
Standard backups are no longer enough. Modern disaster recovery plans utilize the 3-2-1-1-0 rule:
- Keep at least 3 copies of your data (1 primary, 2 backups).
- Store backups on 2 different media types.
- Keep at least 1 copy in an offsite location.
- Keep at least 1 copy offline (immutable or air-gapped).
- Ensure 0 errors during regular automated restore tests.
Ensure your backup credentials are not integrated into your primary Active Directory or Single Sign-On (SSO) systems. If AD is compromised, your backups must remain isolated.
