Subject: Cracking VRRP and GLBP hashes
Hej!
Recently, I worked with Spiros Fraganastasis to add support for cracking VRRP
and GLBP hashes (some weird Cisco proprietary protocols).
$ ../run/glbp2john.py 10-0.0-1412077029.pcap > glbp-hashes
$ ../run/john glbp-hashes -w=wordlist.txt
Loaded 36 password hashes with 36 different salts (hsrp, ...
Press 'q' or Ctrl-C to abort, almost any other key for status
password12345 (56)
password12345 (54)
$ ../run/vrrp2john.py 20-0.0-1412012695.pcap > vrrp-hashes
$ ../run/john vrrp-hashes -w=wordlist.txt
Loaded 1 password hash (hsrp, "MD5 authentication" HSRP, ...
Press 'q' or Ctrl-C to abort, almost any other key for status
password12345 (768)
$ OMP_NUM_THREADS=2 ../run/john --test --format=hsrp
Will run 2 OpenMP threads
Benchmarking: hsrp, "MD5 authentication" HSRP, VRRP, GLBP [MD5 32/64]...
Many salts: 5197K c/s real, 2598K c/s virtual
Only one salt: 4866K c/s real, 2433K c/s virtual
Yes, at some point, we discovered that it is possible to use the existing
"hsrp" format to crack the newer hash types.
...
We have more proprietary hashes to reverse (and could always use more hands).

At some point, we will also be writing patches to enhance Loki to attack the
authenticated versions of the different Cisco protocols.
