I noticed my internet connection was acting a little strange (stuttering up abruptly seemingly randomly), so I thought I'd see what's using it using Zenmap.
I ran "Intense scan" using the latest version of Zenmap and set the target to my modem's default gateway ip.
5 ports open 2 filtered. Most of the service names check out (netbios-ssn, microsoft-ds, icslap, http (Router name as Version)...), but there's this one I find really suspicious:
23 tcp open telnet Openwall GNU/*/Linux telnetd
When I search for windows 10 and telnet nothing noteworthy pops up. If I search Windows 10 Openwall... I get nothing with both those keywords in it. Checking out Openwall, I'm greeted with this Jack the Ripper bit about fast password cracking.
I've never installed any such software directly, and checking out the running services in task manager there's nothing by the name of "telnet" or "Openwall".
Any kind soul willing to tell me if I should freak out or not?
