taking control over a network
If you get connected, then you will be assigned an internal IP address on the LAN. Now, you're part of the network and can do regular network activities…
- Network File Sharing/P2P
- Wake on LAN other PCs
You can log into the router (try default passes –> ie. admin:admin). If it's a Verizon owned, for example, try 192.168.1.1 and login with admin:admin for a generic Westell router.
Now, to be more specific as to what you CAN do once on the network, I'll suggest suggestion the whole network:
[bash]$ nmap –v –sV -p 21,22,23,80,8080,135,5900,6000 192.168.1.0/24
And if you LIVE hosts running certain services behind the ports that you've scanned for, then try enumerating for more information on that service, and exploit a service running on your victim.
That should get you in. Remember, cover your tracks (and possibly leave a backdoor for your next entry).
