Welcome to “cat root.txt” Write-ups

The contents of this blog are from my own experience and methodology on how I solved rooms in tryhackme.com and rooted boxes in hackthebox.eu. This is my personal blog and in no way I am getting paid by both hacking education platforms. THM and HTB do not recommend write-ups to be published in public when a room or box is new. THM room creators normally don’t want any spoilers, hints or write-ups within 3 days of releasing the room. For HTB, the box needs to be retired before write-ups get posted.
