Im on a network, how do I know if somebody in my household is spying on my internet activities?

Question

What Im asking is...is there a way to tell if my computer activites are being spied on by somebody else in the house?

Yep...in fact the person in question does networking and programming for a living...

Answer 1

If someone in your house know networking very well, they can setup something intercept any of your Internet traffic. And you won't know anything about it since they just sit in the middle between your computer and the Internet and intercept your data. So don't even need to touch your computer.

Could be as simple as in the router, they can enable logging so know every single website or any server you went to. And of course you won't know anything unless you have access to the router log.

More advance is a 'Packet sniffer'
A Packet sniffer (also known as network or protocol analyzer or Ethernet sniffer) is computer software (usually) or computer hardware that can intercept and log traffic passing over a digital network or part of a network. So potentially any message (like instant message text or email text), they can capture and see them. Remember instant message and email are just plain text and can easily read if captured.

Answer 2

The person who is the administrator of a router, has lots of control, when it comes to the network.

You can log every website that is visited, by every computer on that network. You can block specific websites, or make only certain websites available.

You can also keep certain computers, on your network, from reaching the internet altogether.

However, these things are usually done as a security precaution only. They are most likely not being used to spy on you, but to ensure that your network is not being attacked.

Some of the sites you may visit, may seem harmless, but some of the people on them are not. They look for weaknesses, in a network, which are usually people.

Anything more detailed that a log of websites visited, such as specific conversations, etc.. ; involves using software/hardware directly on your computer.

If you think you are being spied on, maybe you should just simply ask the person you think is responsible.

But one think you should always remember, when using the internet; everything leaves a trail.

Answer 3

You don't even have to be on a network. For example, someone could install a "keystroke logger" on your computer. Then when you're not at home, they can go see every single keystroke you typed. They could get your passwords that way, for example.

There are also programs out there that will keep track of every single website you go to. These types of programs are actually useful for parents who have young kids, and want to track what Internet content they're seeing. But yes, it's a violation of privacy.

And yes, if you're on a network, then someone could install a program that intercepts every single thing your computer communicates over the Internet, except for very secure transactions, such as credit card information on a secure website like Amazon.com.

But, spies would have to be pretty computer-savvy.

By the way, "anti-spyware" only protects against one type of spyware, not all types of spies.

Answer 4

some routers do furnish pastime monitoring. in spite of the indisputable fact that, viewing the contents of the pages you bypass to (like your emails and private messages) is difficult and uncommon in such classes. If a keylogger has been put in on the computing device, he might want to view what you're typing, yet no longer what others are typing to you. it really is likewise conceivable to view your computing device over the community. highly if you're utilizing Vista or Mac OS X Leopard and he's conscious the password to the account you're utilizing. i wish this helps.

Answer 5

Detection is easy but to counter is difficult. It is obviously a man-in-the-middle attack. Why not, you create another subnet with firewall as protection. You get the person, mac addresses and refuse access.It is the one possible way.

Answer 6

Yes there are ways. But you'd have to be a computer geek to know if they installed software on your computer.

Most likely, if they didn't install software, there's no spying going on.

Answer 7

The yahoo! toolbar have anti-spyware. So, if somebody want to spying on you, the yahoo.! toolbar will told that some1 spying on you. Click on it, then click spyware . And you will see the person IP Address and name of the person.
