Greetings to All,
I wonder how to add custom hash type in hashcat . Code: md5(md5($password).9486)Any idea how to add that in hashcat ? Looking forward for your kind response. Regards Net_Spy

Can you guide me , where I can fine ticket portal to open a ticket for this.

Trac is here and you may need to register if not already done (since trac is seperate from the forum and you need to create a new account there).
The algorithm you want to request is md5(md5($pass).$salt) ... since of course the devs would not add a algorithm with hard-coded constants (9486). There are already "similar" algorithms, like md5(md5($salt).$pass) - see here . In theory you could use a dictionary containing only 9486 and an external salt list (-e argument)... but I wouldn't really recommend it since it may be *much* slower than a new hash mode that does it the other way around (i.e. $salt is salt and $pass is the pass): md5(md5($pass).$salt). Note: if such an algorithm would be implemented you still may need to either use -e for the external salt (in this case only a file containing the number 9486), or you need to append to *each* hash in the hashlist ":9486").

See http://hashcat.net/wiki/doku.php?id=example_hashes , hashcat supports 2 vbulletin hash modes (both have some restrictions on the salt length etc).
Anyway, by using -m 2611 == vBulletin < v3.8.5 and using either -e or adding :9486 to each line in the hash list it might work (even if it may be better to add an additional hash mode w/ md5(md5($pass).$salt) since also md5(md5($salt).$pass) is already listed/implemented as seperate hash mode).
