Supernova

Real fucking shellcode encryptor & obfuscator.

Description

Supernova is an open-source tool that empowers users to securely encrypt and/or obfuscate their raw shellcode.

Supernova supports various features beyond those typically found in a common shellcode encryptor tool. Please refer to the Features section for more information.

For command-line usage and examples, please refer to our Wiki.

If you find any bugs, don’t hesitate to report them. Your feedback is valuable in improving the quality of this project!

Features

Supernova offers automatic conversion of the encrypted shellcode into formats compatible with various programming languages, including:

• C
• C#
• Rust
• Nim
• Golang (Community request by @_atsika)
• Python
• Perl
• PowerShell
• VBA (Implemented by @verydamptowel)
• Java
• Ruby
• Raw (Implemented by @y2qaq)

Supports a variety of different ciphers, including:

• ROT
• XOR
• RC4
• AES (AES-128-CBC, AES-192-CBC, AES-256-CBC)
• Chacha20 (Implemented by @y2qaq)

Supports various obfuscation techniques, which make the malicious shellcode appear as if it were:

• IPv4
• IPv6
• MAC
• UUID (Supported by @S1ckB0y1337 & @MikeAngelowtt)

Supernova is written in Golang, a cross-platform language, enabling its use on both Windows and Linux systems.
