Hi

It looks like Hashcat V5 and 5.10 will not crack any PMKID if you combine with rules? Can someone confirm this for me?

So I have a wordlist with the word "babar" and rules that contain "$1$2$3" and it wont crack it.. If I remove the rules and add the password "babar123" in the workdlist it will crack it so I know its working..

PMKID: 7424f0793a69dad6d5a99783bfd5ba0c*48435a33c640*74d21dd784b4*476f206e6177617a20676f:babar123

wireless.txt
7424f0793a69dad6d5a99783bfd5ba0c*48435a33c640*74d21dd784b4*476f206e6177617a20676f

wordlist.dic
babar

1Rule.rule
$1
$1$2
$1$2$3
$!
$@
$#

hashcat64.exe -a 0 -m 16800 -w 3 -r "c:\hashcat5.1.0\rules\1Rule.rule" "C:\hashcat5.1.0\wireless.txt" "E:\DIC\wordlist.dic"

Try: hashcat test_dir.txt -r test.rule --stdout| hashcat -m 16800 '7424f0793a69dad6d5a99783bfd5ba0c*48435a33c640*74d21dd784b4*476f206e6177617a20676f'

"That's a very known "limitation". The rejection test will occur as soon as possible and in most of the
cases makes perfect sense since otherwise too short plains will be transfered to the GPUs. Since hashcat also has a GPU-based
rule engine it is not easy to display also the correct number of rejected plains that were filtered on GPU-site and therefore
for performance reasons the rejection will be done as soon as possible."

Use the -S switch in your command. Slow candidate generation, may have a performance impact compared to --stdout depending on hash type, but in this case shouldn't be noticeable. It will allow status and time remaining as in a normal session

Thank you The_Mechanic, I tried the -S and it worked without any effect on speed. I now understand what has happened is that it rejected all candidate dictionary words of less than 8 characters before it applied any rules..
