Hunt Hypothesis

The ThreatFox: Havoc IOCs rule detects potential adversary activity associated with the Havoc malware family, leveraging known indicators of compromise to identify malicious behavior. SOC teams should proactively hunt for this behavior in Azure Sentinel to detect and respond to advanced persistent threats that may be leveraging Havoc for data exfiltration or command and control operations.
