Hunt Hypothesis

This hypothesis targets the presence of VShell, a lightweight reverse shell tool frequently used by adversaries to establish persistent, low-noise command-and-control channels that often evade standard network monitoring. Proactively hunting for these specific IOCs in Azure Sentinel allows the SOC to identify compromised endpoints early, preventing attackers from leveraging this tool for lateral movement or data exfiltration before they can escalate privileges.
