HackTheBox CTF Writeups is a curated directory of walkthroughs for retired Hack The Box machines. It is designed to help CTF players and cybersecurity learners study complete penetration-testing scenarios in legal practice environments. Entries are organized by machine name and include the target operating system and difficulty level. The collection spans Linux, Windows, FreeBSD, Solaris, and other environments across easy through insane difficulty ratings. Each machine links to a detailed Hacking Articles writeup explaining the associated challenge. The broad catalog lets learners choose labs that match their current skill level or preferred platform. It serves as a searchable learning index rather than hosting an automated Hack The Box client or exploitation framework.
