Review of the rock solid Debian 10 “Buster” with the stock Gnome Desktop. There have been a lot of security improvements in this release and better support for UEFI secure boot.
Gnome defaults to using Wayland, although Xorg is still available.

#Debian is a slow release and long term support #Linux Distribution, which makes it ideal for using on Servers or corporate environments.

In 2017 Shadow Brokers released a exploit, codenamed EternalBlue, which the NSA had developed to attack Microsoft Windows SMBv1.
The exploit was weaponised and used in WannaCry and NotPetya back in 2017. Two years on, in 2019, companies are still falling victim to this exploit. In this video I discuss the recent example of city of Baltimore, and the older NHS and Maersk examples.

Miss Quids shows how to include figures in LaTeX, including scaling an image based on text width, and also how to wrap text around a figure.

With regards to wrapfig, Miss Quids meant to say that the first {r} refers to where the image shall be relative to the text. Other letters can be used, e.g. l for left.

I have seen attackers’ tactics changing this week in placing a large number of malicious links within a single PDF. However, only one link to a phishing site is chosen randomly at a time. As a result it makes the defenders’ job considerably harder as there are many more sites to block.

Although #Ubuntu 19.04 is an interim release, only supported for 9 months, much of the work has been on fixing bugs and improving performance of the underlying OS and different Desktop Environments.

In this video I look through the changelogs and take a quick look at all the different official derivatives of Ubuntu, including: Xubuntu, Lubuntu, Ubuntu MATE, Ubuntu Budgie, and Kubuntu.
#Linux

Not much in the way of visible changes, as like the other derivatives much of the work has gone into improving performance and bigfixes.

A new release image has been made for GDP Pocket 2, a small Intel laptop.

Ubuntu MATE offers salvation for Unity desktop lovers with their Mutiny desktop. Or you can choose from 7 other desktop layouts

We have been tracking a Nigerian attacker who has been carrying out relentless phishing campaigns against the company I work for. Lately they have made several mistakes, including leaving a WSO Shell accessible on their web servers. So we can look at the root file system and access log files and source code.
