Show HN: SilentArena – Learn ransomware behavior safely (C-based)
github.comSilentArena is a sandbox-style educational tool designed to simulate basic file-encrypting malware behavior — but in a completely safe and reversible way.
It operates only inside a `victim_data/` folder, uses XOR encryption, creates logs, and includes a scanner and optional decryption.
Built in pure C, with a clear structure and safe by design.
