The goal of any unpacker is to find the —the moment the protection stub finishes its work and hands control back to the original program. Themida 3.x Unpacker

If the developer checked the "Virtualize" option for critical routines inside the application, finding the OEP and fixing the IAT will only yield a partially working application. When you run a feature that relies on a virtualized function, the application will redirect execution into a non-existent packer VM stub and crash. Devirtualization Approaches

Unpacking Themida 3.x is rarely a "one-click" affair. Because Themida updates constantly, unpackers are often specialized scripts or manual workflows involving: : To hide the debugger and fix the IAT. TitanEngine : A base for many automated unpacking tools. Virtual Machine macro-analysis : To understand the custom bytecode. | | x64dbg + Scylla 0
