Storm Worm Hoax
This year's April Fool's day trick was to post a near exact copy of the Storm Worm propagation page on our website. The big change that I made was to swap out the executable with a custom compiled one. The code wasn't all that complicated. It was just a normal Visual Studio Win32 console project with a single printf that said, "Yes it's a joke. :)". I then swapped out the debugger file link with a link to YouTube. Most people that downloaded and analyzed the file seem to get the joke at that point but others took concern and were nice enough to notify us of the problem. The file even found it's way onto VirusTotal for scanning.
Here are the complete number of people who downloaded the executables over the day:
foolsday.exe - 266 accesses
kickme.exe - 220 accesses
funny.exe - 1991 accesses
