UPDATE: PSK Cracking using IKE Aggressive Mode

[Michael Thumann <mlthumann () ids-guide de>]

Hi,

we just release a Vulnerability scanner for the PSK Attack we've described 
in april in our paper 'PSK Cracking using IKE Aggressive Mode'.
The scanner is freely available from our website: 
www.ernw.de/download/ikeprobe.zip

The paper itself is available from our website too. Take a look at 
www.ernw.de/download/pskattack.pdf

Today we have some advancements in the cracking tools too. Mao integrated 
the PSK cracking function in his tool Cain & Abel (www.oxid.it). Cain & 
Abel can crack MD5 and SHA1 based preshared keys while ikecrack can only 
crack MD5 based preshared keys.

Cheers
Michael

and buried 20 feet under the ground in a secret location...and i'm not
even too sure about that one
