vmassembler is a small C++ project which uses [flex](https://en.wikipedia.org/wiki/Flex_(lexical_analyser_generator)) and [bison](https://www.gnu.org/software/bison/manual/) to parse `.vasm` files and assemble virtual instructions. The project inherits [vmprofiler](https://githacks.org/vmp2/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.
In order to use the virtual instruction assembler you must first have a few values at hand. You must have an unpacked vmprotect 2 binary. This file cannot be a dump, it must be unpacked. Second, you must know the RVA to the vm entry address of the first push instruction. This first push instruction must not be `push contant_value`, it must be of type `push reg` as the constant values are pushed onto the stack by the generated c++ header file. The last thing you need is a virtual instruction assembly file. You can make one of these easily. Simply open a text editor and create your first label:
***Note: you can use ANY virtual instruction which is defined by vmprofiler... you can see them all [here](https://githacks.org/vmp2/vmprofiler/-/tree/a419fa4633f98e2f819b1119dc0884154e207482/src/vmprofiles)***
