ThreatFox: AdaptixC2 IOCs

Hunt Hypothesis

This hunt targets known indicators of compromise associated with the AdaptixC2 framework, which adversaries use to establish persistent command and control channels for data exfiltration and remote execution. Proactively hunting for these IOCs in Azure Sentinel is critical to identify early-stage intrusion attempts before the adversary can leverage this C2 infrastructure to escalate privileges or move laterally within the environment.

False Positive Guidance

Legacy Application Update via PowerShell: A legacy line-of-business application (e.g., a custom Java-based inventory tool) uses a hardcoded PowerShell script to fetch configuration files or update manifests from a specific IP address or domain listed in the AdaptixC2 IOCs.
- Filter/Exclusion: Exclude alerts where the initiating process is powershell.exe or pwsh.exe and the parent process is a known application binary (e.g., java.exe, dotnet.exe) from the legacy application’s directory path.
Scheduled Backup Agent Communication: The enterprise backup solution (e.g., Veeam, Commvault, or Rubrik) agent communicates with the backup server or repository over a specific port or IP that matches one of the AdaptixC2 IOCs, particularly if the backup server is hosted in a DMZ or cloud region with a static IP.
- Filter/Exclusion: Exclude alerts where the source process is a known backup agent service (e.g., VeeamBackupSvc.exe, commvaultagent.exe) and the destination IP matches the backup server’s documented IP range.
Internal Monitoring/Telemetry Agent: An internal IT monitoring agent (e.g., Datadog, New Relic, or Splunk Universal Forwarder) sends telemetry data to a collection endpoint that shares an IP or domain with the AdaptixC2 IOCs, often due to shared cloud infrastructure or CDN usage.
- Filter/Exclusion: Exclude alerts where the source process is a known monitoring agent (e.g., datadog-agent.exe, splunkforwarder.exe) and the user context is a service account (e.g., svc-monitoring, svc-telemetry).
Development Environment API Testing: Developers in a test environment use tools like curl, wget, or Postman to test API endpoints against
