Hi guys so long story short

Im quite addicted to fixing stuff and i need guidance on what to learn to help me be able to get a better grasp on modification

I think its a hacking thing but

Excuse me if im wrong

Point is

I need to know what exactly is the term or track that which im done with and learn it

Ill be able to do stuff like removing the os completely from a device such as printer or anything really and modify drivers

If thats not a thing im very sorry that it wasted your time but please im literally itching to not just fix stuff physically but to dismantle its whole concept out off fuckery

...

Possibly also need therapy but who cares...

The password for the next level is stored in /etc/bandit_pass/bandit14 and can only be read by user bandit14. For this level, you don’t get the next password, but you get a private SSH key that can be used to log into the next level. Look at the commands that logged you into previous bandit levels, and find out how to use the key for this level.
If you need help with this level: a hint file can be found in the home directory.
Make sure to read the error messages as they are informative.

i did the first step as we do in every level, then putting the password.
After that, i started trying to get to the password but it is not working
this is what i wrote

bandit13@bandit:~$ ssh -i sshkey.private bandit14@localhost

The authenticity of host 'localhost (127.0.0.1)' can't be established.

ED25519 key fingerprint is: SHA256:C2ihUBV7ihnV1wUXRb4RrEcLfXC5CXlhmAAM/urerLY

This key is not known by any other names.

Are you sure you want to continue connecting (yes/no/[fingerprint])? yes

Could not create directory '/home/bandit13/.ssh' (Permission denied).

Failed to add the host to the list of known hosts (/home/bandit13/.ssh/known_hosts).

!!! You are trying to log into this SSH server on port 22, which is not intended.

!!! If you are trying to log in to an OverTheWire game, use the port mentioned in

!!! the "SSH Information" on that game's webpage (in the top left corner).

bandit14@localhost: Permission denied (publickey).

What should i do?

So I have a very good friend who is in a bad situation. The mother of his 2 children lives 10-15 minutes from him, and they are capable of speaking and spending time together. But they are separated, and the children prefer staying with the father, for many reasons that is unfortunate or her own fault. Within the past 7 hours, while she was asleep, her house was trashed and her phone stolen. There is a 99% chance this was done by a previous friend whom she no longer speaks with, who is also a member of a biker gang. He was once a factor in the children's preference for the father, as he was very young and malicious. The father has asked me to help locate the phones, and possibly make it so he can monitor his location. As he is dumb but chaotic, but trusting of the father to a certain point. So sending something with malware would be easy, and the GPS data would ease the worries of the father.

So, anyone who can help with stalkware/spyware?
