By setting breakpoints on suspected protected functions, you will eventually hit the VM Entry.
Search for the telltale signature of VMProtect. Typically, it pushes a context structure and a pointer to the bytecode onto the stack before calling vm_enter . In x64dbg, look for a pattern of:

Identify basic blocks and branches (conditional jumps) within the bytecode.
Often stored in the RSI register, pointing to the custom bytecode. By setting breakpoints on suspected protected functions, you
Running the sample inside a hardened, custom hypervisor prevents the binary from detecting the analysis environment. Conclusion
VMProtect 3.5.0 incorporates sophisticated anti-debugging and anti-analysis features designed to thwart reverse engineering attempts. These include: In x64dbg, look for a pattern of: April
5. Notable Tools in the VMProtect Reverse Engineering Ecosystem
Basic arithmetic operations executed on the virtual stack. VM_AND / VM_OR / VM_XOR: Bitwise logic operations.
VMProtect operates by disassembling the target executable's x86 bytecode and compiling it into a proprietary, polymorphic bytecode language executed within a custom interpreter at runtime. The interpreter uses a stack-based architecture, making it fundamentally different from the original Intel 8086 instruction set the code was designed for.
In IDA/x64dbg: look for a loop with a large jmp table (handler dispatch).
