Each target may have a different decryption routine. You cannot apply a single signature. themida 3x unpacker

The Import Address Table (IAT) is a primary target for unpackers. Themida destroys the original IAT and replaces it with dynamic wrappers. When the application needs to call a Windows API, it jumps into the Themida engine, which resolves and executes the API call internally.
