A prominent Spanish fashion retailer, with locations across major cities and a significant e-commerce presence, partnered with CrimsonLabs to assess their ransomware readiness. The retailer sought to protect their operations after observing increased cyber attacks in the retail sector.

The Challenge

The retailer’s complex infrastructure included:

  • Multiple retail locations with integrated POS systems
  • Regional distribution centers
  • High-volume e-commerce platform
  • Large-scale customer loyalty program
  • Real-time inventory management across all channels

Simulation Approach

CrimsonLabs conducted a three-phase simulation:

  1. Initial breach through a simulated phishing attack targeting the Madrid flagship store
  2. Lateral movement across store networks
  3. Attempted encryption of critical systems including:
    • Inventory management
    • Customer loyalty database
    • POS terminals
    • E-commerce platform

Key Findings

The simulation revealed:

  • 36-hours average detection time
  • 120-hours response time to isolate affected systems
  • Backup systems successfully prevented data loss
  • Critical vulnerabilities in cross-location communication
  • Gaps in weekend incident response procedures

Results

Post-simulation improvements reduced potential ransomware impact by 60%. The retailer implemented enhanced security measures, including:

  • Revised incident response playbooks
  • Enhanced cross-location security protocols
  • Strengthened POS system isolation
  • Improved backup verification procedures

This case study demonstrates the value of proactive ransomware defense through realistic simulation exercises.
