BCS Systems — Ransomware recovery & Azure migration

Challenge

BCS Systems experienced a ransomware outbreak that encrypted several on-premises file servers and affected business-critical applications. Existing backups were partially compromised, and the customer faced significant downtime and the risk of extended data loss. The immediate priorities were containment, rapid recovery of services, and a plan to reduce future risk by moving essential workloads to a more resilient cloud environment.

Solution

Our team executed a rapid incident response: we isolated infected systems, performed forensic triage to identify the threat vector, and removed persistent malicious artifacts. Where safe, we restored services from known-good backups. For longer-term resilience we designed and implemented a phased migration of critical servers and applications into Azure, using hardened virtual networks, managed identities, and automated backups. We also implemented improved monitoring, endpoint protection, and a documented runbook for future incidents.

Results

• Operations restored to critical capacity within 72 hours.
• Migration of priority workloads to Azure reduced mean time to recovery and improved availability.
• Introduced immutable backup and automated recovery checks to prevent future data loss.
• Improved overall security posture with endpoint hardening and continuous monitoring.

Tools & software used

• Veeam Backup & Replication (immutable backups)
• CrowdStrike Falcon (endpoint detection & response)
• Azure Site Recovery & Azure Blob Storage (cold backups)
• Microsoft Azure (IaaS, VNets, Managed Identities)
• Microsoft Intune for endpoint configuration and policy management
