usb keyloggers

[kitesurfer]

are these legal? if so where can I buy them?

[ACtheTROLL]

yes and no
just like a knife or gun - having one isn't always illegal .... it's the use you put it to
why would you want to?
don't you think a usb device is going to be a bit obvious

but the main question is why would you want to?

You can buy them on many websites on the internet. Just Google "keyloggers".

As for justifiable uses, there are lots.

In my office, we had a security guard that was spending hours on his nightshift looking at p0rn on computers that had to be 24-7. Yes, we had sophisticated website blockers and other technical stuff on the servers that could have stopped him and recorded the activity, but we found it much easier to plug a forty quid keylogger in place instead. The keylogger is invisible in "My Computer" until a special password is entered after which the data can be downloaded to a USB key. The security guard was confronted with the evidence and promptly sacked.

All the same, I do appreciate that they can be a curse if used incorrectly. I know someone who uses one to monitor his children's internet usage - these keys can store around a year of keystrokes. The ethics of this are debatable.
