This page contains an overview of all boxes and challenges I have completed so-far, their category, a link to the write-up (if I made one) and their status (retired or not). Note that, if a challenge has been retired but I have never attempted to complete it, it will not be included in this list. Also note that, for any write-up of the Active challenges, you need the HTB{} enclosed flag to read the write-up. For any of the active boxes, you need the root flag without HTB{} enclosed or, for newer boxes, the root hash or administrator hash.
