Malware has been found hidden inside an innocuous 'waterfall' screensaver .deb file made available on popular artwork sharing site Gnome-Look.org.
The .deb file installs a script with elevated privileges designed to perform a DDoS attack as well as keep itself updated via downloads.
The dodgy screensaver in question has since been removed from gnome-look and this incident was a very basic, if potentially successful, attempt.
If anything this incident highlights the need to be careful what you download and where you download it from.
