Electron_Shell - Developing A More Covert Remote Access Trojan (RAT) Tool By Leveraging Electron's Features For Command Injection And Combining It With Remote Control Methods

Electron_shell

Features

• Supports almost all operating systems

  • mac
  • linux
  • windows

• Supports almost all desktop applications developed based on Electron

  • QQ
  • Microsoft Team
  • Discord
  • GitHubDesktop
  • 淘宝直播
  • vscode
  • and more (https://en.wikipedia.org/wiki/List_of_software_using_Electron)

•  All malicious operations are executed by the injected program, those commonly used trusted programs

• Bypass of Network Access Control Policy for Applications by Zero Trust Sandbox

• Verified that it will not be discovered by the antivirus software below

  (Please note that a simple command call has been implemented here, and some behavior based heuristic checks will still prompt , bypass AV is not a key issue to be addressed in this project)

  • Windows Defender
  • avast
  • 火绒
  • 360
  • 腾讯管家
  • virustotal

Intro

An increasing number of desktop applications are opting for the Electron framework.

Electron provides a method that can be debugged, usually by utilizing Chrome's inspect function or calling inspect through Node.js. In this project, the implementation of inspect was analyzed, and a method for automatically parasitizing common Electron programs was developed.

By establishing a connection with the Command and Control (C2) server, a simple remote control is achieved.

Due to the widespread trust of most antivirus software in these well-known applications (with digital signatures), executing malicious commands in the program context provides excellent concealment and stability.

For these injected applications, it is necessary to carefully consider the potential legal risks brought by such actions. When users analyze program behavior, they may be surprised to find that the parent process executing malicious behavior comes from the application they trust.

 Usage

C2 Server Setup

1. Deploy a server and obtain a public IP address
2. and then exec command: nc -lvnp 8899

Generating Implants

1. clone this project

2. modify build.config

   injected_app:  The electron program you want to inject
   c2:            set c2_Public IP and c2_netcat Port
   

3. exec node build.js, and then pkg to an execute program

4. Send to victim, and get electron_shell 

Kage - Graphical User Interface For Metasploit Meterpreter And Session Handler

Kage (ka-geh) is a tool inspired by AhMyth designed for Metasploit RPC Server to interact with meterpreter sessions and generate payloads.
For now it only supports windows/meterpreter & android/meterpreter.

Getting Started

Please follow these instructions to get a copy of Kage running on your local machine without any problems.

Prerequisites

• Metasploit-framework must be installed and in your PATH:
  • Msfrpcd
  • Msfvenom
  • Msfdb

Installing

You can install Kage binaries from here.

for developers

to run the app from source code:

# Download source code
git clone https://github.com/WayzDev/Kage.git

# Install dependencies and run kage
cd Kage
yarn # or npm install
yarn run dev # or npm run dev

# to build project
yarn run build

electron-vue officially recommends the yarn package manager as it handles dependencies much better and can help reduce final build size with yarn clean.

For Generating APK Payload select Raw format in dropdown list.
