Exploiting CVE-2019-0708 Remote Desktop Protocol on Windows

April 22, 2020 By Albert Valbuena

The CVE-2019-0708 is the number assigned to a very dangerous vulnerability found in the RDP protocol in Windows sytems. This is also known as the ‘Blue Keep’ vulnerability. The issue was so critical that Microsoft did even release patches to unsupported operating systems such as Windows XP or Server 2003. To this day there are […]

A few useful network commands

March 16, 2020 By Albert Valbuena

Troubleshooting network issues with simple commands is not a very difficult topic once there is a little toolbox to pull from. Needless to say networking topics can be very complicated and any specialist on the field will tell you how cumbersome it can really get. However with a few set of commands one can get […]

The root account

April 23, 2017 By Albert Valbuena

Users. What the hell you mean by “root”? Are you a Windows user? I bet you have the user account badly configured. By default Windows is installed under the Administrator account. And nobody bothers to change this and add a second account. That second account should be an underprivileged one. If you own the computer […]

How to set CentOS 7 repositories

February 24, 2020 By Albert Valbuena

CentOS is the free open source replica of the well known Red Hat Enterprise Linux (RHEL). With a very good reputation because of its stability and performance RHEL is nowadays the dominating GNU/Linux distribution in the enterprise environment. As a gift, in a similar fashion to Microsoft’s Windows trial versions (without limits to the use), […]

How to setup MariaDB master-slave replication on FreeBSD

April 23, 2022 By Albert Valbuena

Having all the data in just one server is not the best idea. Especially when talking about a database server. Spreading information in several boxes is a good measure to prevent data loss but also for performance. A MySQL/MariaDB master-slave replication scheme is often used as a good solution for both, data redundancy and speed. […]

How to install the bash shell on FreeBSD

January 28, 2019 By Albert Valbuena

Believe it or not the Bash shell does not come installed on the system. By default FreeBSD uses the sh shell (after the rewrite under the BSD license on 1989 of the original Bourne Shell found on UNIX, which had inherited the ‘sh’ name from the original’s Thomson shell), the C shell or the tcsh […]
