Hunt Hypothesis

This detection rule identifies adversary activity linked to the VShell malware by monitoring for seven specific Indicators of Compromise (IOCs) known to facilitate command and control or lateral movement within Azure environments. Proactively hunting for these signatures in Azure Sentinel is critical because early identification of VShell IOCs allows the SOC team to isolate compromised assets before the threat escalates into a broader network breach.
