For a few years, modern flagship phones have had comparable specs to mid-tier computers, which gave me a thought: why can't you just run a full-fledged virtual machine on your phone?
The short answer is “because virtual machines don't quite work like that”. The long answer is a bit too complicated for my small brain to properly explain, but the point is that running a virtual machine from your phone isn't really feasible for the average user.
HackPark is a Medium difficulty room, although it guides you along fairly well for the initial foothold, and it's pretty easy to root if you do proper basic enumeration.
By now, everyone has done a writeup of the Overpass room on TryHackMe, but I've decided I want to try my hand at it anyway. Hopefully someone will find it helpful.
