Critrical 802.11b flaw found
Posted: 14-May-2004 [Source: Computerworld]

[A flaw in wireless technology found that is reportedly able to lead to the breakdown of some critical infrastructures in five seconds.]

"Professor Looi's (QUT's) PhD students - Christian Wullems, Kevin Tham and Jason Smith - discovered the flaw while investigating mechanisms for defending wireless devices against being hacked.

The findings are to be presented to the Institute of Electrical and Electronic Engineers (IEEE) Wireless Telecommunication Symposium in California Friday.

In effect the flaw allows for the disruption of the standard 802.11b radio frequency developed by the IEEE to transmit data.

The result is that the wireless devices cannot communicate with each other and service is denied."
