hashcat and rules, bug or not - kerk - 02-07-2012
it's looks like a bug for me, maybe i'm wrong and it is some kind of feature
create test rule with one symbol ":"
in docs/rules.txt it's:
#define RULE_OP_MANGLE_NOOP1 ':' // does nothing
create "wordlist" file with numbers from 1 to 10000
generate from this "wordlist" md5 hashes
try to recover generated hashes with "wordlist"
try to recover generated hashes with "wordlist" and "nothing" rule
so, these steps
Code:
C:\>cat test.rule
:
C:\>hashcat-cli32.exe -V
0.38
C:\>del hashcat.pot
C:\>perl -e "for(1..10000){print \"$_\n\"}" > words
C:\>perl dict2hash.pl words >md5h
C:\>hashcat-cli32.exe -m0 -n1 md5h words
... cut ...
All hashes have been recovered
C:\>grep -c '' hashcat.pot
10000
C:\>del hashcat.pot
C:\>hashcat-cli32.exe -m0 -n1 -r test.rule md5h words
... cut ...
Index.....: 1/1 (segment), 10000 (words), 58894 (bytes)
Recovered.: 2500/10000 hashes, 0/1 salts
... cut ...
Progress..: 10000/10000 (100.00%)
... cut ...
C:\>grep -c '' hashcat.pot
2500
C:\>cat hashcat.pot

9997so, with applying the rules something gone wrong?
looks like every 1 of 4 passwords was restored and others are not
hashcat-cli32.exe runned on win xp pro sp2 , proc: intel core 2 duo e6600
i've tried -n parameter 1,2,4, thinking that depends on processor's cores\threads, but it did not help
any thoughts on this?
sorry for my lame english
