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!
Security is important. So important, that Google will downgrade the position of your website if you do not have an SSL certificate. In the past, there was a big SSL certificate market where you could buy a certificate from many resellers. Luckily this process is a lot easier nowadays and in this post I will explain you how you can use a tool made by Mozilla and many others to get your free SSL certificate.
