This hunt identifies potential compromise by matching network traffic or endpoint activity against known indicators of compromise associated with the Havoc framework, a popular post-exploitation tool used for establishing command-and-control channels. Proactively hunting for these IOCs in Azure Sentinel allows the SOC to detect stealthy adversary presence and lateral movement attempts before they escalate into full-blown breaches or data exfiltration events.

Scenario: A network operations engineer runs a standard vulnerability scan using Nessus or Qualys against the internal asset inventory. The scanner may probe specific ports or send handshake packets that match the network-level IOCs (e.g., specific TCP/UDP port combinations or banner strings) associated with the Havoc C2 framework.
Vulnerability-Scanner security group or tag assets with role=scanner from the IOC match criteria.Scenario: An IT administrator performs a manual port audit using Nmap or Angry IP Scanner to verify firewall rules or identify open services on a new server deployment. If the scan includes the specific service banners or port combinations listed in the Havoc IOCs, the detection engine will flag these benign administrative probes.
admin-task=port-scan or exclude traffic originating from the Admin-Workstation VLAN when the destination is a known internal IP range.Scenario: A DevOps team deploys a new microservice that uses a standard web framework (e.g., Node.js or Python Flask) which, by default, listens on a port or returns a header string that coincidentally matches one of the Havoc IOCs (e.g., a specific User-Agent string or a default port like 8080/8443 if included in the IOC set).
service-type=internal-api or filter out traffic where the User-Agent header matches known internal development tools (e.g., curl, Postman, or internal SDKs).Scenario: A scheduled Windows Task or Cron Job
