Hunt Hypothesis

This hunt detects adversary behavior involving the deployment of Vidar malware by matching network and endpoint telemetry against a curated set of 67 specific Indicators of Compromise (IOCs). A SOC team should proactively hunt for these signals in Azure Sentinel to identify early-stage infections and prevent potential data exfiltration or lateral movement associated with this prevalent infostealer.
