F-Secure Security Labs has a video in YouTube showing the outbreak of a Trojan with the name Small.DAM (Storm-Worm). It is a Trojan that arrives on the system as attachment file to spam emails.
The WorldMap Live shown in the video is a map view of the report sent by the F-Secure security products on detection of the Trojan. F-Secure security products such as Internet Security 2007 sends back the IP address of the infected computer. The WorldMap Live software then calculates the geographical location of the computer and fills up the world map.
In the video, you will notice most PC users schedule to scan for infections at midnight when you see the most detections.
The WorldMap Live is available for internal use only. The public viewable version is much less impressive. Want to protect your PC? Read my previous article on the trends of security threats in year 2007.
