as many of us often use some keyboard shortcuts in our everyday activities using our PC, we may find the command CTRL+C as one of the most useful ones as it can copy blocks of texts or images from one location to another. little did we know, it can cause many dangers in securing our private data. Yuga of Ambot Ah points out that any copied data using the CTRL+C is stored in clipboard and is accessible from the internet by a combination of Javascripts and PHP/ASP/CGI.
just try to do the simple task below as proof:
- copy any text by Ctrl+C
- click this link:

you will see the text you copied on the screen which was accessed by this web page.
got it? so as that webby said, 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.
this works only in browsers like internet Explorer and Netscape. Firefox users need not to worry much though you should be aware that net attacks never always passes through browsers. so no matter what browser you are using, clipboard contents can still be accesible in not only one way.
always keep in mind, there's no way the safest once you are connected!

Wow! You've really opened my eyes about this issue! I had no idea that my text in the clipboard could be read by anyone online. I'm so glad that I'm using Firefox, so I should be mostly safe. Sometimes I do use other browsers, though. But now I will know for sure not to keep any sensitive information on the clipboard! Thank you so much!! ^_^ I thought that i was pretty internet savvy, but I sure didn't know this! *laugh*
