Ransomware Recovery & Hardening for Medical Practice

The Incident

A multi-location medical practice in Florida was hit by a ransomware variant that encrypted their EHR database and patient scheduling system. The attackers gained initial access through an exposed RDP port on a legacy Windows Server 2012 R2 machine with a weak password — no MFA, no VPN, no IP allowlist. Automated scanners found it within hours of being exposed. No offline backups existed.

What We Did

• Contained — isolated infected segments, identified variant, obtained working decryptor from threat actor
• Recovered — restored EHR data, validated integrity, rebuilt scheduling from clean images
• Hardened — closed RDP exposure, deployed network segmentation, immutable offline backups, MFA on all remote access, EDR with ransomware rules, 24/7 Auditor monitoring
