Episode 52 — Recognize Data Exfiltration Patterns and Advanced Threat Techniques at Scale
Data exfiltration represents the final, often most damaging stage of a cyber attack, and this episode focuses on recognizing the technical patterns associated with unauthorized data movement. We define exfiltration as the removal of sensitive information from trusted organizational boundaries through paths like web uploads, cloud sharing, or encrypted tunnels. A key concept is the staging phase, where an attacker collects and compresses data internally before initiating the transfer. The discussion identifies the professional pitfall of missing slow, low-volume exfiltration that occurs over long periods to avoid triggering volume-based alerts. We explore detection clues such as unusual use of compression tools and new outbound spikes to unfamiliar destinations. Best practices include monitoring data access patterns and limiting bulk export capabilities on sensitive databases.
