How do hackers perform penetrationed router tests over the Internet?

Thank you,

Well that really depends on how their network is setup. If you have full permission to test it - your best start is checking for ports and services that might be vulnerable.
A lot of routers for even members on HF are actually open to the net on port 8080 and have a default admin admin login. From there you can just mess with all their router settings lmao.

A lot of routers are insecure due to the fact that they usually come with default and easily-guessable passwords, as well as the firmware they're running generally are riddled with trivial security vulnerabilities that allow authentication bypasses (and even code execution on the router. Most people who purchase/use routers aren't technically inclined, so they don't bother to change the default login credentials, setup strict firewall rules, update their firmware or disable unused services that can be abused locally (LAN) by malware or CSRF, or remotely (WAN) by malware or an attacker
