Hey, At Defcon last year, Joshua Wright released a paper documenting a number of flaws in LEAP, in particular relating to sniffing the challenge-response traffic, compromising the username, and cracking the user password offline. His paper is available from http://home.jwu.edu/jwright/presentations/asleap-defcon.pdf I am currently undertaking a wireless test for a client who I've found is using LEAP. I've sniffed a number of LEAP challenge-response frames, and it would be great if I could perform some active attacks to spoof LEAP-logoff and STA deauthenticate frames, sniff more LEAP challenge-response traffic, and perform the offline cracking operation as described by Joshua Wright. Joshua wrote a tool called asleap / asleap-imp, which he demonstrated at Defcon, but did not release. I have yet to find asleap available online, although various media sources state that the tool will be available in February. I even mailed Joshua, but he hasn't yet responsed. My question is if anyone knows of any tools or hacks of software like kismet that can perform any element of this LEAP attack?
