Sharperner : Simple Executable Generator With Encrypted Shellcode

Sharperner is a tool written in CSharp that generate .NET dropper with AES and XOR obfuscated shellcode. Generated executable can possibly bypass signature check but I cant be sure it can bypass heuristic scanning.

Features

PE binary

  • Process Hollowing
  • PPID Spoofing
  • Random generated AES key and iv
  • Final Shellcode, Key and IV are translated to morse code

.NET binary

  • AES + XOR encrypted shellcode
  • APC Process Injection (explorer.exe)
  • Random function names
  • Random generated AES key and iv
  • Final Shellcode, Key and IV are translated to morse code

Usage

/file B64,hex,raw shellcode
/type cs,cpp
/out Output file Location (Optional)
Example:
Sharperner.exe /file:file.txt /type:cpp
Sharperner.exe /file:file.txt /out:payload.exe
