This hypothesis targets the presence of 37 known indicators of compromise associated with unidentified malware, which may signal an active or dormant threat that has evaded signature-based detection. Proactively hunting for these IOCs in Azure Sentinel allows the SOC to identify potential footholds in the environment before they are leveraged for lateral movement or data exfiltration.

Scenario: A DevOps team deploys a new containerized microservice using a custom base image that includes a lightweight, open-source diagnostic tool (e.g., netcat or nmap) for internal health checks. The binary hash or file path of this utility matches one of the 37 IOCs in the ThreatFox feed, triggering an alert on the application server.
dockerd, containerd, crio) or where the file path resides within standard container filesystem mounts (e.g., /var/lib/docker/, /var/lib/kubelet/).Scenario: An IT administrator runs a scheduled PowerShell script to perform disk cleanup and log rotation on legacy Windows servers. The script uses a temporary staging folder (e.g., C:\Temp\cleanup_20241027) to store intermediate files before deletion. The specific combination of the script’s hash and its location in a non-standard temp directory matches an IOC associated with fileless malware droppers.
svc_backup, admin_cleanup) and the process command line contains specific keywords like Remove-Item, Clear-RecycleBin, or logrotate, provided the parent process is powershell.exe or pwsh.exe.Scenario: A security engineer performs a manual vulnerability assessment using a legitimate open-source tool like Masscan or ZMap to scan internal IP ranges. The tool’s binary hash or its network connection pattern (high-volume SYN packets) matches an IOC for a known scanning malware variant (e.g., Sharky or Masscan-based backdoors) in the ThreatFox feed.
