Hunt Hypothesis

This hunt identifies potential VShell implant activity by correlating known IOCs against network and host telemetry to detect unauthorized remote access sessions. Proactively hunting for these indicators allows the SOC to uncover stealthy backdoors that adversaries use to maintain persistent access, ensuring rapid containment before the threat actor escalates privileges or exfiltrates data.
