Tools For Unpacking Malware, Part 1. Dumping executables from RWE memory

This is the first part of a series of articles (at least I will write a second part and i hope to continue) where I will write about different ways that I use to unpack malware, and where I will share some tools and scripts that I use frequently for this purpose. I hope these articles and tools will be useful for you.

Anti-Antidebugging WinDbg Scripts

In this post I would like to share some scripts for WinDbg that they were useful for me while I was reversing malware with antidebug tricks.
