Cyron

Welcome to Project Cyron, the first vm register based challenge made by over_on_top on discord aka overpower.

❗ Goal of the challenge

• Noobs: Find the secret combination.
• Nerds: Recreate the algorithm and decrypt the secret message.

❓ Why I released this code?

• My previous VM challenge wasn't a real obfuscator, since it completely lacked an encryption mechanism, and as a result, it wasn't complex enough
• To fix that, I decided to create a new challenge, this time register-based instead of stack-based, with the addition of encryption and other security measures designed to make it more intricate and, above all, more fun to tackle.

⚙️ Features

• Anti-tampering
• Custom opcodes
• Encrypted constants
• Polymorphic obfuscation
• Custom virtual machine (VM)
• Encrypted identifiers (names)
• Full variable and function renaming

🏆 Winners

• 🥇 ProccessHacker | 10 hours
• 🥈 Doremii109 | 2 days
• 🥉 None
