![]() ![]() Fairly obvious, it restarts our executable.ģ. As you’ve probably already guessed, it opens a file into Olly.Ģ. Let’s go ahead and take a second to give a brief explanation as to what each of these buttons does.ġ. At the top portion of Olly, we have a long line of horizontal buttons that will save us having to even use the menus for the majority of the time. So, first things first, let’s take a look at the interface, keeping in mind that I am using OllyDBG v2.01 Alpha 4. The act of being able to walk through a program step-by-step makes it enormously easier to find things that normally you couldn’t (or rather, had a very hard time finding.) And at the same time, it allows us to go to things like conditional statements, and either change the condition, or change the whole statement, all in real-time without even having to recompile or restart the application. Aside from the basics of the debugger, it is more widely used for the purposes of reverse engineering. Now you may be wondering, what does Olly have to do with you, then? Well, it has quite a lot to do with you, actually. And by doing so, this allowed them to find where the error actually happened in real-time, and made it much easier for them to fix it. ![]() It allowed them to go through their application step-by-step, monitoring most every action that the application took. Olly is an x86, 32bit debugger originally intended for developers who had problematic errors in their applications. Check the bottom of the post.įirst of all, a question many people ask is: What is Olly? The answer is simple, really. Check attachments for extra_crackmes.rarĮdit 2: Added a quick video on solving "Crack Me"s 3, 4, and 5. (Also known as Olly Debugger, and, as I like to call it Olly).Įdit: Added three more "Crack Me" applications for you guys to mess with/learn with. This is a simple introduction to the program OllyDBG. So, since three (four?) people requested that I post something like this I’ll give it a shot. Well, I originally did a video on this last night, but on my internet, uploading wasn’t going to happen. ![]()
