1. Prerequisites

Backup platform access (logs, configuration, inventory, immutable storage settings)
Access to the relevant backup target platforms (cloud storage, virtualisation, file systems)
Identity and authentication logs for backup admin accounts (to assess exposure)
Isolated test environment for controlled restoration tests
Malware scanning capability for validating restored data

2. Step-by-Step Instructions

Identify Backup Infrastructure Exposure
- Determine:
  - Backup servers impacted
  - Backup credentials exposed
  - Administrative access abuse
  - Backup network exposure
Review Backup Activity Logs
- Check for:
  - Backup deletion attempts
  - Retention policy changes
  - Immutable storage tampering
  - Failed backup jobs
Validate Backup Availability
- Confirm:
  - Recovery points exist
  - Offline backups available
  - Immutable backups intact
  - Replication status healthy
Perform Controlled Restoration Tests
- Restore:
  - Sample files
  - Critical systems
  - Test workloads
- Validate:
  - File integrity
  - Malware absence
  - System functionality
Identify Recovery Constraints
- Determine:
  - Recovery time estimates
  - Resource bottlenecks
  - Infrastructure dependencies
  - Restoration sequencing requirements
