Security analysts are warning computer users about a new and potentially destructive Internet worm that can obliterate important documents. The worm, called Kama Sutra, is making the rounds now, but is scheduled to execute its first massive attack on February 3. Detected last week, the malicious worm targets computers running Windows and spreads primarily by copying itself to shared network locations and then sending itself to e-mail addresses found on afflicted computers. With subject lines that read "the best videoclip ever," "give me a kiss," and "school girl fantasies gone bad," the worm entices computer users to open the attached file. "This worm feeds on people's willingness to receive salacious content on their desktop computer, but they could be putting their entire company's data at risk," said Graham Cluley, senior technology consultant at Sophos. According to Sophos, on the third of each month, the worm will attempt to disable existing antivirus and firewall software and also will delete specific files, such as Microsoft Office documents.
