Decrypt Moonsec V3 ⟶

Drop your findings below. Happy (ethical) hunting. Stay tuned for next week’s post: "Dynamically Resolving Moonsec’s API Hashing Without Execution."

In the world of malware analysis, few cat-and-mouse games are as intense as the battle between packer authors and reverse engineers. Moonsec, a well-known (and infamous) crypter/packer often sold on underground forums, has seen several iterations. Moonsec V3 is a particular beast, known for its heavy anti-debugging, anti-VM, and multi-layer obfuscation. Decrypt Moonsec V3

Here’s a generic Python decryptor based on reversing the XOR+ROL routine: Drop your findings below
