vmassembler - VMProtect 2 Virtual Instruction Assembler
vmassembler is a small C++ project which uses flex and bison to parse .vasm files and assemble virtual instructions. The project inherits vmprofiler which is used to identify vm handler's, provide them with a name, immidate value size, and other meta data to aid in assembling virtual instructions.
Contents
The repo contains the following notable folders and files:
dependencies/- vmprofiler is the only dependency for this project...src/- source code for the vmassembler...compiler.cpp- responsible for encoding and encrypting virtual instructions...parser.cpp- a singleton class which is used inparser.y...parser.y- bison rules for parsing tokens. This contains only a handful of rules...lexer.l- lex rules for the vmassembler...
Usage Requirements
In order to use the virtual instruction assembler you must first have a few values at hand. The required values are listed below:
vm_entry rva- relative virtual address to a vm_entry...image base- image base value from optional headers...- a path to a vasm file is required...
advancement- which way the virtual instruction pointer advances...out path- a path to where the vmasm file will be stored...
