# Step 2: Remove PKCS7 padding decrypted = unpad(decrypted, 16)
From reversed samples, the pattern is:
It replaces standard Lua bytecode with a proprietary instruction set, meaning standard decompilers like unluac cannot read it directly. Decrypt Moonsec V3
If you are trying to learn how a specific feature works, it is often faster to from scratch by observing the script's behavior in-game rather than trying to untangle a virtualized mess.
# Step 3: Custom post-decrypt XOR (anti-forensic) xor_key = decrypted[0:8] # first 8 bytes become XOR key output = bytearray() for i in range(8, len(decrypted)): output.append(decrypted[i] ^ xor_key[i % 8]) # Step 2: Remove PKCS7 padding decrypted =
often host community-shared snippets of Moonsec V3 code that you can study to understand the VM's logic. A note on ethics:
out = decrypt_moonsec_v3(enc_data, key)
Moonsec V3 rarely runs the payload in the same process. Instead, after decryption, you'll see:
