Seems that American and Russian Law Enforcement successfully revealed the info about creators of famous Storm Worm. The Storm Worm attacked email boxes for at least the past 3 or 4 holidays in the US and worldwide. Storm has been designed so well and it is so hard to capture because it mutates every 30 minutes, making it impossible for antivirus software to catch it, and there are no central command and control servers to take out like most other worms. Once a computer is infected, any kind of malicious code can be downloaded, from a spam bot to a key logger. It has been most commonly used to send out spam.
