Share the WiFi of a friend and be sure he's not spying on me

Postby palimmo » 25 Aug 2014 18:23

Hi.
A friend and I have reached an agreement and we share his wifi signal (protected with password) of his flat above mine.
How can I be sure that he's not spying on me?
Should install something on my machine in order to be pretty sure he cannot easily trace my navigation and know that "hey, you read that online newspaper. Me too! will not happen?
Am I just paranoid and should I stay calm and relaxed because nothing could happen? :mrgreen:

thanks!

Your friend probably doesn't care so much. It depends on his router. Most routers will have the option to display all open connections, but will only display the IP addresses. In that case it would be tiresome to Reverse DNS them to find out that 'ip.add.re.ss' connects to 'solydxk.nl'.

As your friend owns and has control of the router/NAT, he has the ability to see what websites you visit by logging into the router and looking at open connections (and possibly reverse DNSing them). Even if you had isolated the network computers (so they could not share data) for example using VLANs or other form of partitioning, friend could still look at the router's traffic log or sniff your packets over the air (if said friend was a hacker).

If you were very paranoid and had access to a computer outside of your network, you could set up SSH on that computer and create an SSH tunnel which will obscure your traffic; else you could use tor or a proxy/VPN service that encrypts data before it leaves the network.

Thanks a lot!
I was thinking to do something easier like installing some softwares or setting up a firewall... but as far as I have understood from you it would not be very useful and necessary. :lol:
