SCRIPTING VECTORS

BAT / VBS / JS Obfuscation

Home > Scripting

Technical Overview

Raw scripting files (Batch, VBScript, JScript) are powerful automation tools native to Windows. The challenge in red teaming is not just execution, but obfuscation and delivery. These vectors focus on complex encoding to bypass static signatures and AMSI (Antimalware Scan Interface).

Key Mechanisms

  • Obfuscation: Layered encoding (Base64, Hex, XOR) to hide the true intent of the code.
  • Polyglots: Files that are valid in multiple formats (e.g., a GIF that is also a JS file).
  • AMSI Bypass: Techniques to disable or fool the runtime scanner in JScript.

Red Team Advantages

  • Versatility Can be easily modified on the fly and embedded in other delivery chains.
  • Lightweight Text-based payloads are extremely small and easy to exfiltrate or download.
  • Native Execution Scripts run directly via Windows interpreters without additional dependencies.
