Ransomware Contained in 4 Hours, Business Saved
Containment time
4 hours
THE CHALLENGE
A healthcare SaaS company with 150 employees detected unusual activity on a Saturday night. By Sunday morning, ransomware had begun encrypting servers containing electronic health records for 30,000 patients across 45 healthcare providers. The attack exploited a zero-day vulnerability in their VPN appliance, and the threat actor had established persistence across multiple systems. HIPAA breach notification timelines were ticking, and the company faced potential regulatory fines exceeding $1M if patient data was confirmed exfiltrated. Their internal IT team had no incident response experience and was overwhelmed.
OUR SOLUTION
Our incident response team was on-site within 2 hours of the initial call. We immediately established an incident command structure, isolated affected network segments to prevent lateral movement, and deployed forensic tools to assess the blast radius. Our threat intelligence team identified the ransomware variant and the threat actor's TTPs, which guided our containment strategy. We preserved forensic evidence chain-of-custody for potential law enforcement involvement, recovered all systems from verified clean backups within 48 hours, and conducted a thorough forensic investigation confirming no patient data was exfiltrated. Post-incident, we designed and deployed a comprehensive MDR solution with 24/7 monitoring.
Immediate Triage & Containment
Within 2 hours of engagement, our IR team was on-site. We isolated affected systems, identified the ransomware variant (LockBit 3.0), and contained lateral movement by segmenting the network at the switch level. The spread was halted within 4 hours.
Forensic Investigation & Evidence Preservation
Captured forensic images of all affected systems, analyzed the attack chain from initial phishing email to privilege escalation, and confirmed through network flow analysis that zero patient data was exfiltrated. This was critical for HIPAA reporting.
Recovery & Restoration
Rebuilt affected servers from clean golden images, restored data from verified clean backups (tested regularly under our recommendation), and brought systems online in a staged rollout with enhanced monitoring on each.
Post-Incident Hardening
Deployed 24/7 MDR, implemented network segmentation, enforced MFA organization-wide, and conducted staff security awareness training. Built a comprehensive incident response plan with quarterly tabletop exercises.
THE RESULTS
- Ransomware contained within 4 hours of engagement with zero further spread
- Zero patient records exfiltrated — confirmed through comprehensive forensic analysis
- Full business operations restored within 48 hours from verified clean backups
- No HIPAA breach notification required, avoiding potential $1M+ in regulatory fines

CLIENT TESTIMONIAL
“When ransomware hit on a Saturday night, I thought our company was finished. Threat Contain had a team on-site within two hours, and by Monday morning we were operational again. They saved our business — that is not an exaggeration.”
