Use the "Fix Dump" feature in Scylla to attach the reconstructed IAT to your newly dumped file.
The OEP is the location in the memory where the actual application starts after the packer has finished executing. Load the binary into x64dbg. Run the application and monitor the memory map. Look for a newly allocated, executable memory segment.
Test the dumped executable to see if it runs without the debugger. ⚠️ Challenges with Code Virtualization
Themida 3.x shifted the paradigm by introducing advanced obfuscation and virtualization:
It uses the RDTSC instruction to measure execution time. If code runs too slowly (indicating a debugger stepping through), it crashes on purpose. 2. SecureEngine® Code Virtualization

A driver-based tool to hide debuggers at the kernel level.
An advanced user-mode anti-anti-debugger plugin for x64dbg to hide from Themida's detection loops.
