Microsoft Windows Defender Evasive JS.Net and HTA - Metasploit
This page contains detailed information about how to use the evasion/windows/windows_defender_js_hta metasploit module. For list of all metasploit modules, visit the Metasploit Module Library.
Module Overview
Name: Microsoft Windows Defender Evasive JS.Net and HTA
Module: evasion/windows/windows_defender_js_hta
Source code: modules/evasion/windows/windows_defender_js_hta.rb
Disclosure date: -
Last modification time: 2018-10-11 17:38:47 +0000
Supported architecture(s): x64
Supported platform(s): Windows
Target service / protocol: -
Target network port(s): -
List of CVEs: -
This module will generate an HTA file that writes and compiles a JScript.NET file containing shellcode on the target machine. After compilation, the generated EXE will execute the shellcode without interference from Windows Defender. It is recommended that you use a payload that uses RC4 or HTTPS for best experience.
Module Ranking and Traits
Module Ranking:
- normal: The exploit is otherwise reliable, but depends on a specific version and can't (or doesn't) reliably autodetect. More information about ranking can be found here.
