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

even too sure about that one
