Click to save the current state of the memory sections to a new PE file (e.g., dumped.exe ). Step 3: Reconstructing the Import Address Table (IAT)
When an executable is processed by Themida 3.x, its original structure is heavily modified. If you open a protected binary in a PE analyzer like or Detect It Easy (DIE) , you will immediately notice several anomalies:

Older software packers simply compressed or encrypted an executable (.exe or .dll) and tacked on a "stub" at the entry point. When the program ran, the stub would decrypt the original code into memory and jump to the Original Entry Point (OEP). Unpacking these files was a matter of letting the stub do the work, pausing execution at the OEP, and dumping the memory.

Once paused at the OEP, you cannot just click "Dump." You must use (integrated into x64dbg) to fix the imports: Target the OEP address.
For a reverser looking to unpack Themida 3.x, there is no substitute for a deep understanding of the Windows PE format, assembly language, and the specific architecture of the Themida Virtual Machine. Automated tools exist but are often unreliable or specific to certain builds. As such, Themida 3.x remains a highly effective deterrent against generic cracking and unauthorized analysis, maintaining its reputation as a top-tier commercial protector. What actually exists are (for x64dbg, IDA Pro,

Once execution jumps outside the Themida protected sections into a newly allocated or standard code section, you have likely hit the OEP. Step 4: Reconstructing the IAT (Import Address Table)
Before executing a Themida 3.x binary, your analysis environment must be fully stealthy.
Requires a 32-bit or 64-bit Python interpreter to handle the corresponding target binary.
Detects if the program is running under a debugger like x64dbg, IDA Pro, or OllyDbg.
This is indeed an interesting story—though not because a full, public, drag-and-drop unpacker for Themida 3.x actually exists. In fact, the lack of one is precisely what makes the tale compelling.
He set a hardware breakpoint on the GetModuleHandle API call—a common trick where the packer asks the system where it is before finally handing over control to the real program. Click.
