At the last week held TechEd 2004 in the VS, hackers have continuously tried to sabotage Microsoft's wireless network. This network was put in place for visitors of TechEd 2004 to take part at online conversations. After 48 hours the network had more than 8000 hack attempts. One hacker tried to spread a new worm from the exhibition hall on to the wireless network. "What they did not realize is that this is one of the closely monitored networks on the world", according to a technician. Unbelievable!
