Near-miss passage: Sigma rule: Detects the execution of Python web servers via command line interface (CLI). After gaining access to target systems, ad. Logsource: linux / process_creation. Rule: title: Python WebServer Execution - Linux id: 3f0f5957-04f8-4792-ad89-192b0303bde6 status: experimental description: 'Detects the execution of Python web servers via command line interface (CLI). After gaining access to target systems, adversaries may use Python''s built-in HTTP server modules to quickly establish a web server without requiring additional software. This technique is commonly used in post-exploitation scenarios as it provides a simple method for transferring files between the compromised host and attacker-controlled systems.
