Hello everyone Yesterday I made some magic in our code and today I want to show you this. The most important thing that I wrote is the implementation of the linked list which can store all instructions from the file. Let's see what we already have. We have these functionalities: - a file has to be read as an argument - react if the file is not specified - react if the file extension is not right - react if the file is not found Today we will add these to our interpreter: - read brainfuck instructions from a file - check if the char from the file is brainfuck instruction - if it is brainfuck instruction then add it to the linked list

Hi there This blog is about hacking, but also about programming. So I came up with an idea to write a Brainfuck Interpreter in C language. I will show you my road from the first day of writing this project to last day when the project will ends. I hope that you will enjoy this series of articles.

Hello guys Sincerely I didn't have much time lately. But I've got holidays now and I will update a blog as soon as possible because I solved a few interesting tasks. Today I'm gonna show you how to crack Uber Keygen challenge. This hacking exercise is from PWNing CTF from 2017. Sincerely I had some problems with this task, but finally, I can do a write-up and I'm happy about it. :)  Let's get started.

Today I'm gonna show you a solution of a task from pwning2017 CTF created by p4 team. I think this challenge is much simpler than the earlier one so I hope that you will understand it quickly. Here is a content ( https://pwning2017.p4.team/task/simple_keygen ):

About half year ago I wrote post on the Polish forum for programmers named 4programmers. ( post ) Most of the users have recommended me tasks from the one of the CTF's, which is created by the polish CTF team p4. Since that time I learnt some Reverse Engineering and Programming stuff so finally I decided to solve one of the problem. I love to solve RE tasks so that quest gave me a lot of fun. Let's try to figure it out one more time.

Hello on my first blog! This site is about reverse engineering, binary exploatation and programming. I am a beginner so I will write the basics of above topics. (at least at the start of my adventure :) )  My idea for this blog is very simple - I want to describe my road from a beginner to an expert in RE and binary exploatation.  I thnik my articles about IT will be helpful for such beginners as me. And that is one of my goals - share the knowledge with other people. Constructive critism is welcome. I wish you pleasant reading and want to invite you to comment. Enjoy!
