3.x Unpacker — Themida

: A notable dynamic unpacker that supports Themida 2.x and 3.x for both 32-bit and 64-bit PEs. It automatically recovers the Original Entry Point (OEP) and reconstructions the obfuscated Import Address Table (IAT) .

: The protector converts original code into a custom bytecode language executed by a internal virtual machine. IAT Obfuscation Themida 3.x Unpacker
