My Approach to Natas Level 11 (a Web Security Game)

Recently I came across the concept of CTF (Capture The Flag) which are security competitions and I really enjoy these kinds of the competitions. One of my favorites is OverTheWire. They provide different kinds of games and one of these is Natas, in which you need to attack a webserver. The concept is simple: the creator of the game designs a normal functioning webserver and intentionally puts in a bug. We need to find a password in order to get to the next level which can be found by exploiting the bug. That’s why it is called Capture The Flag. So lets get started!

Hands-on: Creating Neural Networks using Chainer

This tutorial is a practical guide which helps you to create Neural Networks in Chainer. The focus is not on the architecture of the networks (more about Neural Network architectures is found in this post), but it is focused on creating a pipeline. We will take a simple classification problem as an example and create the pipeline for training and testing the network and how to evaluate the model.

Create a Character-based Seq2Seq model using Python and Tensorflow

In this article, I will share my findings on creating a character-based Sequence-to-Sequence model (Seq2Seq) and I will share some of the results I have found. All of this is just a tiny part of my Master Thesis and it took quite a while for me to learn how to convert the theoretical concepts into practical models. I will also share the lessons that I have learned.
