Special thanks to my brothers @S1ckB0y1337 and @IAMCOMPROMISED, who provided invaluable assistance during the beta testing phase of the tool.

Grateful acknowledgment to @y2qaq and @VeryDampTowel for their valuable contributions.

Special thanks to my friend @MikeAngelowtt for all our evening discussions during the development process.

Special thanks to my friend Efstratios Chatzoglou and his tool named Pandora, which inspired me to improve the beauty of this file.

This tool was inspired during the malware development courses of MALDEV Academy.

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:

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