To begin with, malware is just a piece of code like every other program. For example, if you want to write an undetectable keylogger, one should first check how a normal game would work in Windows. #Critical ops hack android 2018 working windows#įor example, every time you press a key in the game -> up, down, left, right, ctrl etc, a Windows handle is being called which captures the keystroke and performs some action according to it. So, if I could just write a program with the same code which runs in background and just slightly modify it to store the keystrokes in memory rather than performing some game-based action, it becomes a keylogger. #Critical ops hack android 2018 working code# I can then simply convert it into a module and push it to a reverse shell for dumping keystrokes from a remote machine. However, there are few pre-requisites before delving into the world of malware. Here are some of the pros and cons of different programming languages when it comes to developing your first FUD: Which protocol will it use – TCP/HTTP/UDP or HTTPS? Reverse shell for Red Team/Phishing/Targeted Attack Simulation Something that automates some task when executed rather than giving a reverse shell Something that spreads automatically like a worm What kind of malware do you want to write? Below is a set of the most important questions before you start writing a malware: We need to do some homework before we get started. We will be using TCP connection throughout the blog, however the malware we will be writing can be easily ported to HTTP. For the purpose of this blog, we will be writing droppers and stageless malware, since writing a staged malware would require us to go in deep into assembly, create shellcode and send it to buffer to execute it.īut since we want to write something which is quick and fairly straightforward, I will be writing these programs in C and C++ and use Python 3 for the server code.
