A new worm that targets three critical holes discovered in Windows last week has emerged. The Zotob worm is spreading like sasser, and has been called faster than previous computer worms. Zotob is known to exploit holes in Windows 95, 98, ME, NE, 2000 and XP, and could allow hackers to remotely access PCs running those operating systems. Once it has infected a PC, Zotob also has the ability to prevent a user from getting online assistance. Prior to Zotob, Microsoft last week issued patches for six vulnerabilities, three of which were branded as critical. Researchers are most worried about the hole that affects Windows Plug and Play system, which Microsoft outlined in this bulletin. Researchers are also growing increasingly concerned about mobile viruses. Last week, Cabir circulated around the World Athletic Championships in Finland, infecting mobile phones. In Mobile viruses could score big at soccer World Cup, John Blau of the IDG News Service looks at the potential for mobile viruses to spread at mass gatherings. Meanwhile, attacks were reported for a critical flaw in Veritas’ Backup Exec software. Technology Industry
