Hello Everyone,
I just found out, that my GF's Phone (Redmi Note 10 Pro) is still on MIUI 13.0.16 and Android 12 with Security updates 2022-11-01 therefore.
The device is eol, but all sources I could find tell me that the last available version should be Android 13 with MIUI 14.0 or HyperOS 1.0 https://hyperosupdates.com/hyperos/sweet
The Device was set to automatically download and install system updates but apparently it didn't update for 1.5 years. And manually hitting the "search for updates" button only returns the info that no updates are available.
Has anyone of you some idea what could be the issue here?
Privileged ports can be used by processes that are running without root permissions. So if the sshd process would crash or stop for some other reason, any malicious user process could pretend to be the real ssh server without privilege escalation. To be fair this isn't really a concern for single user systems. But setting up fail2ban or only making ssh accessible from a local network or VPN would probably be a more helpful hardenening step
And regarding port 2222 it is the most popular non-provileged port used for SSH according to shodan.io So you ain't gaining much obscurity
