Companies now get hacked, on average, 30 times a week, with 15 percent of attacks resulting in system entry. For the first three months of this year, more than 42,000 attacks were reported to CERT monitors. And that's only a partial reading: The FBI says just one in five attacks are reported, thanks to reluctance on the part of companies to broadcast security failings to customers and shareholders. Worse yet? The new viruses are becoming more sophisticated: Slammer scanned more than 55 million computer systems per second, 100 times faster than the previous Code Red virus, says Allan Paller, director of research at the SANs Institute, a Washington, D.C.-based security information center.
