In this article I'm going to show you how to change value of variable during run time. There are many tools around how to do this easily, but I will focus on the way doing it programatically, specifically using C language.

Tools I will use: Cheat Engine 6.0

Here is a simple code for login, I know it's weak and vulnerable, but for proof of concept and for the ease it's ok.

Format String Vulnerabilities With printf Example

Feb 06, 2012 - 5:42 PM - by Karpov2007

This time I want to speak on the 'printf' function. Everybody has heard of software vulnerabilities and that functions like 'printf' are outlaw. But it's one thing to know that you'd better not use these functions, and quite the other to understand why. In this article, I will describe two classic software vulnerabilities related to 'printf'. You won't become a hacker after that but perhaps you will have a fresh look at your code. You might create similar vulnerable functions in your project without knowing that.

STOP. Reader, please stop, don't pass by. You have seen the word "printf", I know. And you're sure that you will now be told a banal story that the function cannot check types of passed arguments. No!... [Read More]

Initialization Function Or Constructor - Which is Better?

Jan 30, 2012 - 9:38 PM - by Karpov2007

We decided to write several small posts on how C/C++ programmers play with fire without knowing it. The first post will be devoted to an attempt to explicitly call a constructor.

Programmers are lazy creatures. That's why they tend to solve a task using minimal code amount. This aim is praiseworthy and good. But the main point is not get too involved in the process and stop at the right time.

For example, programmers are too lazy to create a single initialization function in a class so that it could be called from various constructors later. They think: "What for do I need an extra function? I'd rather call one constructor from the other". Unfortunately, sometimes programmers can't solve even such a... [Read More]
