Rapid DFIR Response Case Study for Pharmaceutical Company

This case study details a rapid Digital Forensics and Incident Response (DFIR) engagement for a U.S.-based pharmaceutical technology company facing a significant network intrusion. The incident was identified when Microsoft Defender for Endpoint flagged unusual activity, revealing an active compromise that exploited a misconfiguration in the company's SonicWall SSL-VPN. The CyberProof DFIR team was engaged to conduct a structured investigation, utilizing targeted triage collections and mapping attacker activity to the MITRE ATT&CK framework across eight tactics. The investigation identified critical security gaps, including the absence of continuous monitoring, which allowed the attacker to operate undetected. The response included swift containment of the threat actor's presence, preventing potential ransomware deployment or data exfiltration. Following the incident, the client chose to engage CyberProof for ongoing managed security services, establishing a partnership focused on continuous monitoring and threat detection.
