Coordinated attacks from up to 15 different locations on several continents have been detected, and Navy experts believe that the attackers garner information by probing Navy Web sites and then share it among themselves. "These new patterns are really hard to decipher--you need expert forensics to get the smoking gun," said Stephen Northcutt, head of the Shadow intrusion detection team at the Naval Surface Warfare Center. "To know what's really happening will require law enforcement to get hold of the hackers' code so we can disassemble it." The new method involves sending as few as two suspicious probes per hour to a host computer, a level of interest that usually won't be detected by standard countermeasures. But by pooling information learned from those probes, hackers can garner considerable knowledge about a site. -o- Subscribe: mail majordomot_private with "subscribe isn".
