9. Real-World Case Studies
Ransomware in Healthcare SaaS
Issue: EDR triggered ransomware behavior on key application servers.
Impact: Partial data encryption and exfiltration.
Our Role: Activated IR playbook, isolated infected systems, and conducted forensic timeline analysis.
Outcome: Identified initial access vector, contained lateral movement, coordinated regulator disclosures.
Cloud Account Compromise in FinTech
Client: FinTech company with multi-region AWS deployment
Findings: Stolen IAM credentials used for unauthorized infrastructure changes.
Outcome: Traced access from compromised employee laptop, rotated credentials, rebuilt IAM policies.
