Key Loggers...?

Question

Is it possible for someone to install a keylogger program on a computer which is protected with a firewall?

Answer 1

When it comes to software everything is possible.

Answer 2

Sure, there are lots of ways. The easiest, of course, is to walk up to the computer and install... a firewall won't save you from physical access vulnerabilities. Software-wise, all it takes is a trojan... you download something (possibly spyware or other code without your explicit approval), and it installs the keyboard sniffer behind your firewall.

Firewalls don't make you safe. Antivirus software doesn't make you safe. Antispyware software doesn't make you safe. All of these things can help, but you need to be smart about the things you're doing online. The only sure way never to have computer problems is to never use one.

As an extra-bonus tip from some anonymous paranoid guy, try running as a limited user. Many bad things get in because your browser or your email program have too many permissions... if you don't need to be administrator (or root), don't run that way and you'll have far fewer problems.

Answer 3

Yes, if you downloaded any bad attachments or the person had physical access to your computer.

A hardware keylogger is a device between your keyboard and computer; they are usually bland and an inch long.

A software keylogger is a piece of software that runs, either recording logs for pickup or sending them over the internet.

Hope this helps!

Answer 4

There are also key loggers that attach inline with your keyboard wire. They have a small amount of memory and can usually store about 40,000 characters. You might be so busy looking at software that you dont know what is plugged into your wires that are behind your desk.

Answer 5

in theory, no, not unless they have access to the computer.

however, I've come across programs that can bypass most brand name firewalls, so it isn't an immpossibility either.
