More than 10 years ago, if someone unleashed a computer virus, there was close to zero chance at catching the criminal. Five years ago, the cops might catch up with the hacker, eventually, after months or years of searching.
Apparently, authorities in Morocco and Turkey are on top of things because they've already arrested two men in connection with the recent international network disruption. The two were accused of releasing the Zotob worm in early 2005 and also may have released Rbot and Mytob worms as well.
True, the worm wasn't nearly as damaging as other more infamous worms. And yes, there were perhaps other leads due to earlier releases. Even still, maybe this is a sign that more serious manpower will be placed on stopping hackers from attempting to control the Internet.
