Use Scylla’s IAT Autosearch and Get Imports features to rebuild the Import Address Table.

Older versions of Themida relied heavily on traditional packing techniques: compressing the code and decrypting it into memory at runtime. Reverse engineers could easily find the Original Entry Point (OEP) and dump the memory.

Place a memory breakpoint on the original code section (usually .text ). When Themida’s stub finishes decrypting that page and jumps to the real code, the breakpoint triggers. This is the classic method.

After reaching OEP, you must use tools like Scylla (integrated into x64dbg) to reconstruct the Import Address Table. Essential Tools for Themida 3.x Unpacking (2026)

Originally developed as unlicense by ergrelet and now maintained as UnpackThemida , this Python 3 tool remains one of the most popular solutions for dynamic unpacking. It supports both 32-bit and 64-bit executables, handles EXEs and DLLs, and can even process .NET assemblies.

The dumped binary often has misaligned sections (raw vs virtual size). A file rebuild must correct Characteristics (executable, readable) and recalculate checksums.

Usually built into x64dbg or used standalone to dump processes and rebuild the IAT.
