ShadeLoader

Description

ShadeLoader is a shellcode loader that utilizes process hollowing and XOR encryption techniques to download, decrypt, and inject shellcode into a legitimate process.

How It Works & Features

1. Initial Access (main.exe):

   • main.exe starts a legitimate process, cmd.exe, in suspended mode.

2. Downloading and Decrypting Shellcode:

   • cmd.exe downloads the encrypted shellcode from a specified URL.
   • The shellcode is encrypted using XOR to obfuscate its content during transport.
   • Once downloaded, cmd.exe decrypts the shellcode using a key to obtain the clear executable code.

3. Process Hollowing (Injection into RuntimeBroker.exe):

   • cmd.exe creates a new process, RuntimeBroker.exe, in suspended mode.
   • The decrypted shellcode is injected into the allocated memory of RuntimeBroker.exe.
   • cmd.exe creates a thread in RuntimeBroker.exe to execute the injected shellcode.

4. Self-destruction:

   • Once the shellcode is injected and executed, main.exe self-destructs.

5. VM Protection and Anti-Debugging

   The shellcode loader detect and protect against virtual machine environments and debugging tools.

   • If the malware detects that it is running in a virtual machine (VM) environment.
   • If the malware detects the presence of a debugger.
   • If the malware detects common VM artifacts or tools indicating analysis.

How to setup

config.h

you can setup shellcode loader 0 = disable | 1 = enable

ENABLE_DEBUG 0 //  if enable its open windows with debug logs 
AUTODESTRUCT 1  // auto destuct after execution 
SUSPEND_DOWNLOAD 1  //  waiting time before download shellcode from web 
PROTECTION 1 // anti VM / disable IF YOU USE IN ON VM !!! 

main.cpp

in main file you need to configure 2 think

• shellcode URL | line 49
• XOR key use same key for encryption !!! | line 59

The encrypt.py file is included in the project. You can use it to encrypt your shellcode before uploading it.
