>>Write-Ups

In May of 2020, I hacked nearly every active Windows machine on HackTheBox, earning me "Hacker" rank. Currently, I'm working on HTB's Pro Labs in order to gain more experience in lateral movement, persistence, and other intranet post-exploitation techniques.

I admit that I haven't added any new write-ups in awhile. This is mostly due to my rapidly diminishing free time, which is usually taken up by some combination of penetration testing, research, tool development, and gardening.
