• Not throwing shade at vmprotect obv. Mine would be much shittier, lmao.
• Repository will contain both the source code and resources that I've used to learn
• Might be used as a reference for next year d4rkc0de ctf challenges who knows 🗿

Notes

1. VM entry/ exit
2. VM Dispatcher (FDE)----|
3. Handler table <--------| (performs lookup)

Handler table Hardening Techniques

• Populate 256 entries (duplicating handler)
• Duplicate operations like virtual_add1, virtual_add2 -> add in x86_64
• No central VM dispatcher
• Just get rid of explicit handler tables lol.

Instruction Encoding - <opcode> <opcode> <next_handler_address>
