The hypothesis is that the detected URLs are being used by adversaries to download malicious payloads via ua-wget, leveraging compromised or untrusted systems to execute malicious code. SOC teams should proactively hunt for this behavior in Azure Sentinel to identify and mitigate potential command and control channels or data exfiltration attempts.

Scenario: Admin Task to Download a Known Safe File
Description: An administrator manually downloads a trusted file (e.g., a configuration script or patch) using wget from a trusted source.
Filter/Exclusion: Exclude URLs containing known safe domains (e.g., trusted-admin-tools.example.com, scripts.example.com) or specific file hashes.
Scenario: Log Collection Using wget
Description: A log aggregation tool or script uses wget to fetch logs from a remote server.
