What I've Been Working On
To help study for my CompTIA exams and to practice working with all three major operating systems, I set up virtual machines running Windows 11 and Linux using a Parallels, a popular hypervisor for MacOS. While working on my Linux VM I accidentally made a mistake that damaged the root file system and I was unable to boot into the OS. Rather than performing a clean reinstall I wanted to try to fix the error. After researching the issue I figured out how to boot Linux into a repair environment and rebuild the damaged file system using the fsck command. In this video I walk you through my process.
One of my favorite YouTube influencers who publishes IT content posted a very interesting educational video on how to write a simple ransomware program. I was intrigued and decided to try it myself so I could better understand how this type of malware works. Of course, I used my isolated Linux VM to prevent accidental damage to my host OS or any other machines on my home network. Watch me use the Linux command line to create test files and target directories, and Python to write the ransomware. At the end I deploy the ransomware into my test directory and practice using the encryption key to unlock it.
