While the absence of known exploits may lull users into a false sense of security, it is precisely this lack of awareness that makes this attack vector dangerous, increasing the chances of successful and large-scale exploitation....

Introduction Hey everyone, this is a pretty quick article on LUKS drive encryption on Linux with the cryptsetup library. By following the steps outlined here, you will be able to encrypt a drive, decrypt it, and mount it. This was done in a Kali Linux VM and commands may vary for other distributions. Disclaimer: This is not an area that I have much experience in so if details are inaccurate, I apologize in advance....

Linux Penguin Introduction This article will begin with a high-level overview of the Ubuntu boot process and will continue to dig deeper into the role of SecureBoot in it when enabled. Some of the concepts I will be covering include shim, EFI variables, and MOKs. The information presented here was aggregated from the sources listed at the bottom of this article. Commands and example output will also be included to help present the topic in a more comprehensive way....
