With Internet Explorer 7, Microsoft finally addressed a security hole which allowed malicious websites to read and steal your clipboard data.
Yes, your Clipboard text can be stolen, as erstwhile users of upto ‘IE 6 without SP1′ would know. And Microsoft had posted ways on how to prevent it in KB224993. To illustrate this, simply copy (select text, rt click and Copy or Ctrl+C) any part of the text from this web page or anywhere else.

Your IE 7 is expected to throw up a prompt : Do you want this webpage to access your clipboard?
Alternatively, you may simply see your clipboard data staring back at you !
However, inspite of my Vista UAC / Protected IE7 Mode being enabled, ande the default setting of Prompt being in operation, I got no Prompt but could still see my clipboard data exposed ! Strange !?!
To circumvent this Clipboard Hack Problem:
Open IE7 > Internet Options > Security > Custom Level > Security Settings > Under Scripting > Allow programmatic clipboard access > Disable > Apply > OK.
The default is Prompt so a Prompt is expected to be thrown at you. But as I mentioned, I got no prompt and my clipboard data still remained exposed in spite of my default settings! So if you want to be safe, you may Disable it. This will ensure the safety of your clipboards contents.
Always best, NOT to, before surfing the internet, with your Internet Explorer, copy your Credit Card number or a bank Account number or your important Passwords.
But if are still in the habit of doing so, you may like to check out freeware KeepPass. KeepPass provides an option to clear the clipboard after a user-specified number of seconds, as well as an enhanced mode that allows copy pasting only one time.
The Windows Clipboard is very basic in nature and does not offer many features. As a result, many free Clipboard alternatives like ArchiveClipboard, Enhanced Clipboard Manager, CopyCat, Clipboardic, Orange Note, Ditto, Clipboard Magic, etc, are available on the internet.
