I used Windows XP SP3, so if you have a different windows version the addresses may be different as well. Note: the length of the password is NOT static, and there are no anti-debugging mechanisms in effect :-) The goal of the HTS challenge is to create a key generator, but in this tutorial I just want to find out my own dedicated password. This tutorial is purely written to allow you to understand how some (even real-life) protection schemes are implemented.

This tutorial is not meant as a spoiler for HTS since for every username a dedicated password will be computed. Put simple, the program creates a key for your username, and compares it to the one you enter. You can find a copy of the challenge here: I have no idea how to find a memory to change or remove that '' VIP '' sign lolĮDIT 2: I tried opening the DLL file with '' JetBrains '' and copy the whole botting scripts and make my own bot but i couldn't find any scripts on the DLL files and it was full of codes, too complex :D.In this post, we’ll look at an application reversing challenge from HTS () resembling a real-life protection scheme.

There are 3 DLL files ( 1 main DLL ) and the injector of course, what should i do? Are there easier ways to pass this than debugging?ĮDIT: i've tried searching for certain texts in OllyDBG such as '' VIP '', '' free '', '' VIP is required '' and other stuff. How can i crack this? I've tried watching some videos about OllyDBG and changing the memory, but i can't find the memory for those things at all. now after CMD vanishes, it opens a small window that says '' VIP IS REQUIRED '' and also opens a small image called '' splash screen '' and the image has a text '' VIP required '' at the same time it opens my google chrome and takes me to the '' VIP '' website. So when i open the injector ( bot ) it opens a CMD and does some codes, 2 seconds later the CMD is gone and the bot launches.

I don't wanna pay for it and my new project is to crack it free. Basically it's a game bot that used to be free to many players and now the owner of this bot ( who didn't even make this bot 100% himself ) made it VIP version and demands 20 bucks from everyone.
