Redpill – Assist Reverse Tcp Shells In Post-Exploration Tasks
Project Description
The redpill project aims to assist reverse tcp shells in post-exploration tasks. Often in redteam engagements we
need to use unconventional ways to access target system, such as reverse tcp shells (not metasploit) in order
to bypass the defenses implemented by the system administrator. After the first stage was successful compleated
we face another type of problems: “I have (shell) access to the target system, and now what can I do with it?”
This project consists of several PowerShell scripts that perform different post-exploitation functions and the
main script redpill.ps1 that is main work its to download/config/exe the scripts contained in this repository.
The goal is to have a similar meterpreter experience in our reverse tcp shell prompt (meterpreter similar options)
| Folder Name | Description | Notes |
|---|---|---|
| Bin | Contains redpill main modules | Sysinfo | GetConnections | Persiste | Keylogger | etc. |
| Bypass | Contains redpill bypass scripts | Manual Download/Execution required |
| modules | Contains redpill modules | Sherlock | CredsPhish | Webserver | StartWebServer | etc. |
| Utils | Contains BAT | PS1 scripts | Manual execution required |
