With Burp Suite we can initiate dictionary attacks against a website. This time in this simulated attack we will brute force the login field of the Juice Shop web application. We already know the email address of an admin user, so we have to make sure to find the right password. Important note: hacking in the…

In this article we will investigate other functionalities of the Cyber Security test tool Hydra. In one of the previous articles we cracked a user password on a Linux system through SSH. In this example we do not know the exact username of any FTP user. We will create a list of possible usernames along…

The Workstation Player of VMWare is a lightweight and free desktop virtualization hypervisor for non-commercial users. We can learn about virtualization and use it for practicing for free. We can run Windows, Linux and BSD systems on our host machine. The Workstation Player supports Windows and Linux as host for virtualization. The free solution comes…

Microsoft WSL is a very good technology when we want to run Linux applications on our Windows computer. When we install a distro from the Microsoft Store we can only install one instance of it. But with some work we can have multiple instances of the same distro.

The OWASP Top 10 is a standard awareness document that lists the most common weaknesses of modern web applications. Burp Suite will help our application security testing along the Developer Mode of the browser. We will break in to the OWASP Juice Shop, the most modern and sophisticated insecure web shop. Important note: hacking in…

In the first part of this series we found out a user’s password with Hydra with simply attacking his account via SSH. It is a so called “dictionary attack”, and because of the lack of security measurements we could get into the remote system. In this exercise we continue our Ethical Hacking journey and we…

In this presentation we will crack the password of a general Linux user via SSH in our personal lab. The machine from which we start the attack is a Kali Linux box, and the attacked machine is an ordinary Debian Linux on which a user set a weak password. Unfortunately the security settings are weak…

RAID stands for Redundant Array of Independent Disks. It is used for performance, availability and security reasons. Different virtual and physical storage devices can be combined into logical RAID arrays in different configuration levels (like RAID 0 is striping and RAID 1 is mirroring). The array looks like a single device on the computer. RAID…

There are excellent Linux distributions for Cyber Security professionals like Kali. They ship all the the bells and whistles that is needed for the tasks. If we want to learn how to put together our own Penetration Testing system we can use a fresh Debian Linux box. I created a small setup from the NetInstall…
