Hunt Hypothesis

This hunt detects adversary activity linked to the Vidar malware family by identifying matches against a curated set of 34 Indicators of Compromise (IOCs) within Azure Sentinel logs. Proactively hunting for these specific IOCs is critical because Vidar’s modular architecture allows it to persist and exfiltrate data across diverse environments, requiring early detection before lateral expansion occurs.
