pasm

PASM is a Scripting language that i made for fun with a few constraints :

  • the interpreter should be as small as possible and written without the CRT (currently 17ko WITH CRT)
  • the language should be able to call Windows API's

PASM is meant for being used in C2 agents as its interpreter is small.
It can be used with an interpreter to execute local files or as a library in another program to execute files or directly code inside buffers, see Usage.

What pasm is not

PASM is not a language that you daily use, it is not meant for big projects but rather for scripting using existing API (here the Windows API's but it can get extended).

Current state

PASM is in a working state, see code examples. The interpreter works for linux as well, but some API's are Windows only (for now).

TODO :

  • get rid of the CRT (so we can get a smaller PE)

Documentation

The documentation is available here, it should cover everything you have to know before writing scripts.

Usage

Interpreter

make interpreter
pasm.exe code.pasm

As a library

make lib 

Then link the library to your program, see this example.
