ThreatFox: KongTuke IOCs

Hunt Hypothesis

The ThreatFox: KongTuke IOCs rule detects potential adversary activity linked to the KongTuke threat group, which is associated with high-severity malicious behavior. SOC teams should proactively hunt for these IOCs in Azure Sentinel to identify and mitigate early-stage compromise attempts by this sophisticated threat actor.
