UPDATE: PSK Cracking using IKE Aggressive Mode
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

The only secure computer is one that's unplugged, locked in a safe,
and buried 20 feet under the ground in a secret location...and i'm not
even too sure about that one
