Issue with custom rules

[epixoip]

Specifying two wordlists in -a 0 doesn't combine the wordlists, it just runs them in serial. So your command was analogous to the following two commands:

Code:

oclhashcat64 hash.txt dictionary1.txt -r rules/xxx.rule
oclhashcat64 hash.txt dictionary2.txt -r rules/xxx.rule

To combine the wordlists you'd need to use -a 1, but -r does not work in -a 1. What you'd probably want to do to crack passwords like this is use combinator.bin to join the two wordlists, then perform a hybrid attack:

Code:

hashcat-utils/combinator.bin dictionary1.txt dictionary2.txt >dictionary1_2.txt
oclhashcat64 hash.txt -a 6 dictionary1_2.txt ?d?d?d
