Really nice box! User was a bit of a pain cause took me so long to realize that the right file's permission was changed. After that root was not so hard if you have good RE. Thanks @k1llswitch for pointing me the right path for USER :).
root was harder for me since certain application is new to me.
Anyways nice box.
User: Just go basic, no need for advance ROP (ret2lib etc.). This is rated "easy" for a reason.
Root: Google + GPU + proper shell
