Stage 7 of the cyberattack lifecycle: Ransomware Deployment. The final and most destructive stage — the attacker encrypts your systems and demands payment, having already stolen your data as additional leverage.

Attacker Goal

Stage Description

The final and most destructive stage — the attacker encrypts your systems and demands payment, having already stolen your data as additional leverage.

Common Entry Vectors

• Deploying ransomware payloads across the network simultaneously
• Deleting backups and shadow copies to prevent recovery
• Stopping critical services before encryption begins
• Encrypting network shares and cloud-connected storage
• Leaving ransom notes and contacting the victim

Typical Attacker Actions

• Deploys ransomware payload across all accessible systems
• Deletes Volume Shadow Copies to prevent restoration
• Stops database and security services before encrypting
• Encrypts files with strong asymmetric encryption
• Displays ransom demand and provides payment instructions
