Promising result for injecting code…

It’s coming along, but it doesn’t seem to be as easy as I’d have hoped. Sort of have a working example but I don’t want to release it until I can definitely identify what needs to be patched and why and other things like exactly by how much etc for things to be injected. Just a little output of some of my notes from the tests I’ve been running. Nothing to mind blowing but some notes incase someone is interested, slash incase I lose the piece of paper;

Things you must patch to successively inject code:

Length of file in bytes (0×20)
Absolute offet of string table (0×34)
type of checksum? (0×38)
number of fields in field table (0×44)
Absolute offet to field table (0×48)
number of methods in method table (0x4C)
absolute offset of method table (0×50)
another checksum? (0×54)
absolute offset of class definition? (0×58)
