The year hacking became a business
IT was the year when cyber-criminals targeted everything from MySpace to Wikipedia, and even a website maintained by a local boy scout troop wasn't safe.
Computer security experts say 2006 was also the year hacking stopped being a hobby and became a lucrative profession practiced by an underground of computer software developers and sellers.
Like true business people, hackers not only broadened their reach by attacking popular social networking sites, but they also diversified their product line by launching attacks through popular software applications such as PowerPoint and Adobe Reader.
Software makers who try to stop online crooks say they are bracing for a new level of nastiness in 2007, including malicious websites that are booby-trapped with software that automatically loads itself to machines of users who just visit a site.
