hyperion
Runtime encrypter for 32-bit portable executables
Platforms: Linux · Last verified September 6, 2026
This package contains a runtime encrypter for 32-bit portable executables. It is a reference implementation and bases on the paper “Hyperion: Implementation of a PE-Crypter”. The paper describes the implementation details which aren’t in the scope of this readme file. The crypter is started via the command line and encrypts an input executable with AES-128. The encrypted file decrypts itself on startup (bruteforcing the AES key which may take a few seconds) and generates a log file for debug purpose.
Only use this tool against systems you own or are explicitly authorized to test — see the disclaimer.
Getting started
Install on Kali Linux with `sudo apt install hyperion`. See the official Kali tool page and upstream homepage linked above for full usage and configuration details.
