Be Very Careful with this..! ctr+c and ctr+v
We all copy various data by using ctrl+c/Copy for pasting elsewhere.
This copied data is stored on clipboard and is accessible over the net by a combination of Javascripts and ASP.
Just try this:
1) Copy any text by ctrl+c
2) Click the Link: http://www.friendlycanadian.com/applications/clipboard.htm
3) You will see the text you copied on the Screen which was accessed by this web page.
Moral:
Do not keep sensitive data (like passwords, creditcard numbers, PIN etc.) in the clipboard while surfing the web. It is extremely easy to extract the text stored in the clipboard to steal your sensitive information. If sufficient data is stored by mistake it would give away confidential and important information without you knowing about it.
To Avoid This in Interner Explorer
To avoid this, follow these steps:
1. Go to internet options->security
2. Press custom level
3. In the security settings, select disable under Allow paste operations via script.
Now the contents of your clipboard are safe.
Pass this information on to create an awareness of the same.

This extension disables copy, paste and cut events for web pages. This way web pages can no longer use on copy or on paste handlers to learn what you are copying or pasting, they won't even know that you do it at all. And they won't be able to interfere to push unwanted content to your clipboard when you copy text.
There are legitimate uses for these events (online editors) but these are irrelevant for most people. It is very unlikely that you will ever notice the functionality loss.
