Welcome back! If you haven’t checked out my last post on reverse engineering shellcode techniques, you can check it out here! This time we’re taking a look at stage 2 of the shellcode, which we previously decrypted using IDAPython in the last post. We’re going to be covering quite a lot this week, so if […]
It’s been a while since I posted a blog aimed at beginners in terms of reversing techniques for analyzing malware, rather than a “how-does-it-work” type post, so for this blog post I decided to focus on concepts tied very closely to malicious software, such as shellcode, (recognizing and implementing) encryption algorithms, and so on. I […]
(This post is a reupload from my old site which is no longer available – you may have seen it before) If you haven’t read the first post, go check it out here. You can download this keylogger off of VirusBay. So far we have decrypted a whole lot of text using a simple XOR method, which […]

If you haven’t checked out my last post on ISFB where we analyzed the […]

In this post, I will be detailing how to unpack and then analyse the first stage loader executable, and then use […]
