Airports, schools and hotels might want to look closer at the wireless Internet networks they have been installing as a convenience for the must-stay-connected crowd. A new program called AirSnort, released on the Internet this week, lets enterprising hackers easily grab passwords and other sensitive data as they are transmitted through the air - unless certain precautions are taken. "There's going to be some major events that will occur, some takedowns, things like that," said Les Owens, a Vienna, Va.-based expert on wireless security. "I would be cautious (on a wireless network in a public place), a lot more cautious than I would be at home." Because wireless networks broadcast signals over the public airwaves like radios and cell phones, security experts have known for a long time that they are vulnerable to snoops.

AirSnort is a wireless LAN (WLAN) tool which recovers encryption keys. AirSnort operates by passively monitoring transmissions, computing the encryption key when enough packets have been gathered. 802.11b, using the Wired Equivalent Protocol (WEP), is crippled with numerous security flaws. . . . . AirSnort is a wireless LAN (WLAN) tool which recovers encryption keys. AirSnort operates by passively monitoring transmissions, computing the encryption key when enough packets have been gathered. 802.11b, using the Wired Equivalent Protocol (WEP), is crippled with numerous security flaws. Most damning of these is the weakness described in "Weaknesses in the Key Scheduling Algorithm of RC4 " by Scott Fluhrer, Itsik Mantin and Adi Shamir. Adam Stubblefield was the first to implement this attack, but he has not made his software public. To the best of the authors' knowledge, AirSnort is the first publicly available implementation of this attack. AirSnort requires approximately 100M-1GB of data to be gathered. Once enough packets have been gathered, AirSnort can guess the encryption password in under a second. The link for this article located at AirSnort is no longer available. .
