The protected file starts executing inside the Virbox packer code, not the actual application code. You must locate the transition point where the packer jumps to the real application. Run the application in x64dbg.
(C++, Delphi, etc.) using encryption and virtualization. virbox protector unpack
Unpacking is a high-level reverse engineering challenge because it uses multi-layer protection, including Virtualization (VM) , Obfuscation , and Anti-Debugging . The protected file starts executing inside the Virbox
Once the original code is fully unpacked in memory, you need to "dump" it. In x64dbg, use a plugin like to locate the Original Entry Point (OEP) . This is the point where the unpacked code begins. After fixing the OEP and rebuilding the Import Address Table (IAT) with Scylla, you can dump the unpacked process from memory to a new executable file. (C++, Delphi, etc
It converts standard x86/x64 instructions into a proprietary bytecode. This bytecode runs inside a custom virtual machine interpreter.
