Clipboard Hack Problem

Hi  ,
*Ctrl+C may be the most important work we do everyday J. But it’s not a very safe thing to do. Read on to know why.
What happens when you press Ctrl+C while you are online.
We do copy various data by Ctrl + C for pasting
elsewhere. This copied data is stored in clipboard and is accessible from
the net by a combination of Javascripts and ASP.
This is called clipboard hack problem.
*Just try this:*
1. Copy any text by Ctrl + C
2. Click the Link: http://www.sourcecodesworld.com/special/clipboard.asp
3. You will see the text you copied was accessed by this web page.
 *Surprised!* I know you are because i was also surprised to see it.
Do not keep sensitive data (like passwords, credit card 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.
Spread this information to as many friends as you can, to save them from online frauds!
It is true, text you last copied for pasting (copy & paste) can be stolen
when you visit web sites using a combination of JavaScript and ASP (or PHP,
or CGI) to write your possible sensitive data to a database on another
server.
 *How Cipboard Hack is done?*
The Clipboard hack is done by the following Source Code:
 *<script language=”JavaScript”>
var content = clipboardData.getData(”Text”);
alert(content);
</script>
How to safeguard yourself from Clipboard Hack Problem?*
To avoid clipboard hack problem, do the following:
1. Go to internet options->security.
2. Press custom level.
3. In the security settings, select disable under Allow paste operations via
script/Allow programmatic clipboard access. (Scripting sub heading)
Now the contents of your clipboard are safe.
Interestingly, this hack works only on internet explorer, and not on Mozilla
Firefox browser
.
