Samirbous ec791fa67a [New] Long Base64 Encoded Command via Scripting Interpreter (#5891) ...

* [New] Long Base64 Encoded Command via Scripting Interpreter

Identifies oversized command lines used by Python, PowerShell, Node.js, or Deno that contain base64 decoding or encoded-command patterns. Adversaries may embed long inline encoded payloads in scripting interpreters to evade inspection and execute malicious content across Windows, macOS, and Linux systems.

* Update defense_evasion_long_base64_encoded_interpreter_command_line.toml

* Update defense_evasion_long_base64_encoded_interpreter_command_line.toml
