Can my former landlord see what I'm doing on my laptop if we shared wireless at one point?

4 months ago I rented out one side of a 2 family home. The owner lived on the other side. Internet was included in the rent and he gave me his connection information I believe one of them was an SSID which was a long series of numbers and letters and then the wireless network password. I typed it all in and was able to use the comcast internet.He has his own computer that he built and his roommate is an IT specialist.
I lived there for 2 weeks back in September. Now I am logged onto my own families network and internet and I have been since I moved home.
I just saw on a TV show that someone in a similar situation was able to watch a woman on her webcam and view all the websites she's been on. I am really paranoid now.

Nope they can't see anything

Sorry for your paranoid state. Ok lets review . Only way they can see what you are doing is either

1. Remote desktop (hard to get running it comes with windows allows you to see another destop over internet)

2. Teamviewer (possible to use another computer over internet but it does not hide in the background and he would have to have access to your computer once to install the software.) 3.ammyy admin(does the same , gives you control of another persons computer, this one can run as a service and hide without you ever knowing its running, but still requires physicall access ) 4. BOK ( used by techservy people to monitor other people who are logged on to the internet . Its used by criminals. The software itself is easy and free to obtain. The software can be installed using a trojan hourse, thats like a virus.)

If they wanted to spy on you on the same lan they would have to figure out how to log into your system when you were connected to their wifi. If you have set up your computer wrongly this isnt so hard. I think two weeks would require someone with previous experience to crack that one.

The following link give a tutorial on using linux on the same wifi to get command prompt on win xp. From there you can add BOK and the machine is yours . I havent tried it but sounds abit scary

Be sure to run your anti-virus on the machine. Then search combofix & Malwaremalbytes should remove any hidden spying software.

Since you asked for it, I will give it to you straight,

When you were using his network, he would have been able to see what you are doing by using Wireshark or similar network analyser, which means he could have access to all your passwords, mail, facebook and know what you were doing, if you don't have an active firewall, he could have exploited a vulnerability and installed a trojan of his own. Which would have granted him a way to view you on your webcam without you knowing and spying on your other stuff including any files on your computer.

Now, you are no longer using his network, which means to say you are safe BUT, if he did exploit a vulnerability and installed a trojan, then he would effectively have a backdoor and your computer is no longer safe even if you are no longer on his network, he would still be able to access your stuff and webcam as and when he wants.

So it all boils down to:

Did you have an active firewall?

Do you have a good anti virus, internet security program and it was active?

If yes. Then change all your passwords and you should be safe.

If not, then you might want to consider changing your passwords on a different computer and formatting your current one.

Please take note that if he has your passwords, there would be more ways that he could install malware on you even after you have left the place because he would be able to log in to your mail account and forward you malicious emails and make sure that it is in your inbox priority mail because he can access it. Thus highly increasing your chances of self infecting unless you are very savvy and knows what to look out for.
