Ransomware has shifted from simple, isolated attacks to coordinated, human-operated campaigns that target entire organizations.
In this episode of the Endace Packet Forensics Files, Michael Morris talks with Ryan Chapman, SANS Instructor and expert in Digital Forensic and Incident Response (DFIR) about these evolving threats.
Ryan explains how attackers are becoming more methodical and sophisticated, focusing on disabling EDR/XDR solutions to evade detection and leaving organizations vulnerable to advanced attacks.
One of the key challenges Ryan highlights is visibility. Without robust logging, packet capture, and monitoring tools, it’s nearly impossible to understand how an attack happened fully. Even encrypted traffic can reveal critical patterns if analyzed properly.
Ryan shares examples of organizations that suffered reinfections because they rushed to restore systems without identifying the original entry point. Packet capture data plays a vital role in pinpointing when and how attackers infiltrated, ensuring a safe recovery and minimizing disruption.
As ransomware tactics evolve, adopting a Zero-Trust approach is essential. Ryan discusses how limiting permissions and avoiding overly trusting software configurations can help prevent breaches. He cites the Kaseya attack, where some organizations avoided compromise by not blindly whitelisting trusted directories. As attackers increasingly use legitimate tools, verifying all network activity and following least privilege principles are critical defenses.
