How do I tell for sure that I am being spied on?

by mra10 / January 14, 2010 9:17 AM PST

I am pretty sure that the person that I share an internet connection is watching what I do online. Is this even possible? I use VOIP and messenger also...could he see what I type/hear what I say. This person is works in computers and I pay for use of his network via a wireless connection. How can I prove that he is doing this? I'm totally creeped out.

Hard to tell unless you have a tool that says it's clear

Yes, tt will help to monitor

by looking at router's log or any tool.
Depends on what application you will use though but for programs that will make sure that no one is spying on you, monitoring what you are doing, you need anti-spyware, anti-malware or anti-keylogger et al.

Check first your log, if you're behind a router. That will only show who connected to your network but not who watches what you do or type.

The thing is...I don't have access to the router. Only he does...connection is in his name.

Unfortunately, there are many ways to spy on a computer
by tek-ed / January 15, 2010 9:14 AM PST

Check for physical devices. Is there a key capture device plugged into your computer anywhere? Weird bulge in your Keyboard cable? or a strange USB key that you don't know anything about?
Barring this, check to see if you have a rootkit installed on your computer. Do a google search to find install rootkits. There are several well documented rootkit finders out there you can use.
Other than this, there really is no way to protect your network communications...you can run tools like NetMon or ethereal on any computer connected to the network and sniff all traffic that travels on the network. This means that anything you communicate with over the network that is *NOT* an SSL connection (https://xxx.com) is sent in clear-text. This includes passwords, and anything you send. This is possible even if you are using a WEP wireless connection! All someone needs to do is plug an ethernet cable into the router and all traffic is immediately identifiable to the person running the sniffing tool. And there really is nothing you can do. really....nothing. Well...kinda...you can send all email correspondence encrypted using PGP. This will prevent anyone from snooping on your email, but this means that your recipient will need your public key to read the mail. This can be a pain.
There are only three ways I can think of to make sure that your network traffic is safe:
1) Tunnel all your traffic through a VPN. Unless you have one set up for work or something, this is not very feasible.
2) If you're wireless, check to see if there is an open wireless access point you can connect to.
3) If you have a smartphone, you may be able to tether your computer and use your smartphone as your connection.

Other than this, I know that there is a way to detect if someone is sniffing network traffic by searching for promiscuous NICs...but the method escapes me for now

1. Start a new thread, in stead of entering something half way an old one.
2. Tell much more than you do now.

Get your own connection if $$ allows!
by not-a-clue / January 15, 2010 9:46 AM PST

I shared a connection with someone years ago and cut it off quick. He was surfing XXX sites and I was getting emails and all kinds of other phishing emails because of it. Confronted him about it and he was ignorant enough to let me check his surfing habits that he didn't realize remained in his system. I cut him off immediately and thankfully he moved out the next week.
I don't care what any one else says, don't share your Internet service with anybody unless you trust them with your life these days!

He can't spy just having access to the router
by Slackenerny / January 15, 2010 1:57 PM PST

He needs to get something (software (malware) or hardware (some USB dongle)) in the victim's system to spy on someone. That means the fact that he has access to the router doesn't really offer him that much of an advantage in terms of spying. But I'm only talking about encrypted communications only!!!!! Bank sessions and Skype are encrypted for example. Looking at CNET forums is not. If your particular session is not encrypted, then yes, he could spy on you theoretically by the mere fact he has access to the router.

There's a Chinese saying, "if you employ someone don't doubt him, if you don't trust someone don't employ him". If you just don't trust that person that perhaps just get your own connection.

Contact your IP's security department they might be .......

able to track your connection for security breaches. If anyone can find or identify a problem they can.

See how's connecting to your PC through your firewall. Disable those that have no business accessing your PC.

Make sure remote assist is disabled and use the UAC on Windows Vista and Windows 7 OS's.
