Computer security experts say 2006 saw an unprecedented spike in junk e-mail and sophisticated online attacks from increasingly organized cyber crooks. These attacks were made possible, in part, by a huge increase in the number of security holes identified in widely used software products.

“The bulk of the fraud attacks we’re seeing now are coming in Monday through Friday, in the 9-5 U.S.-workday timeframe,” said Vincent Weafer, director of security response at Symantec. “We now have groups of attackers who are motivated by profit and willing to spend the time and effort to learn how to conduct these attacks on a regular basis. For a great many online criminals these days, this is their day job: They’re working full time now.”

Criminals are also getting more sophisticated in evading anti-fraud efforts. This year saw the advent and wide deployment of Web-browser based “toolbars” and other technologies designed to detect when users have visited a known or suspected phishing Web site. In response, many online scam artists place phishing Web sites targeting multiple banks and e-commerce companies on the same Web servers, then route traffic to those servers through home computers that they have commandeered with bot programs.
