Hi Paul, As far as I remember, those $2 should correspond to BlowFish. Anyway, it's the first time I see that on Cisco devices, but that's not my specific field of expertise. John can crack BlowFish (again: AFAIR), so if they're not recognized perhaps something is different. Can you post an example hash? (One for which you know the password). Cheers, Miguel "Paul Bakker" <bakker () fox-it com> 10/12/2003 11:32 To: <pen-test () securityfocus com> cc: Subject: Cisco Catalyst 4006 CatOS Password Hash During a pentest/audit I received from the client the configurations for their Cisco Catalyst 4006 and their other Cisco IOS switches. The passwords in the Cisco IOS configuration file are in in the known usual format of the FreeBSD MD5 hash... Like $1$xxxx$xxxxxxxxxxxxxxxxxxx These are easily crackable/recognized by both John the Ripper and Cain&Abel. The passwords on the Catalyst are in the same format (for the eye), but instead of starting with $1$ they start with $2$..... Both John and Cain do not recognize these hashes. Can anybody shed some light on the hash function used to create these and any tools that can be used to eudit the password strenght of these passwords (Or how John or Cain can be sed for this...) -- Paul Bakker --------------------------------------------------------------------------- ----------------------------------------------------------------------------
