In previous part I’ve given you an overview of strong and weak methods of storing passwords. I’ve told what are the gains of using slow hashing methods and salting as basic methods of protecting passwords. Today, I’m going to perform a simulated attack on passwords to compare efficiency of password cracking. As always all examples […]

Password Recovery – Part 1 – Theory
Have you ever thought what happens when you type your password in a login form? What happens to this top secret data? How is it protected? Note: if you are reading this to get a decent understanding of how you should store passwords, read additional resources at the end. I am not a cryptography expert […]
Pentester Academy GDB challenge (kinda)
A few weeks ago I bough access to Pentester Academy labs to boost my skills, since I do not have solid background in countless fields, my job is mainly writing web applications with a little bit of devops tasks (read: I sometimes modify Dockerfiles) and I rarely have an opportunity to observe how “smart people” […]
How do libraries work? Part 3.
In previous two parts we’ve dealt with creating dynamic libraries on MacOS. Today we’re moving on to different system – Linux. I was planning to go with Windows, but running a web browser while using Virtualbox on my poor laptop is a nightmare and I think I will need to run my old laptop for […]
XSS in Django Admin
AS web developer my every day tasks involve working with Django which I like since it’s quite secure framework (compare with CVE list). Nevertheless as some say: “shit happens” and vulnerabilities are found. Some time ago a problem in admin panel that allowed for XSS attacks was discovered. Example application In order to give you […]
How do libraries work? Part 2
In the previous part we’ve taken a quick look on how to create a dynamic library in MacOS system that would be used as dependent library. While this approach is really straightforward, and has all the advantages of the dynamic loading (smaller binary file size, ability to patch library without the need to recompile entire […]
How do libraries work? Part 1.
I’ve been always wondering what happens, step by step when I use static or dynamic libraries and how can I actually use them. This very first blog post is about writing and including a dynamic library in MacOS system. Linux and Windows are coming soon. I will be mostly focusing on programming part, however, to […]
