Detects the invocation of Windows Subsystem for Linux (WSL) binaries (wsl.exe or wslconfig.exe) using command-line arguments that enable arbitrary command execution, such as -e, --exec, or shell interpreters (bash -c, sh -c), or web-based retrieval tools like curl/wget. This technique is often used to execute commands or download payloads within a Linux environment on Windows, potentially bypassing security controls focused on native Windows processes.
