hashcat Forum

Hi,

I am a novice hashcat user and am having trouble setting proper masks in WPA2.
I know that the password is 8 characters long and contains capital letters and numbers, e.g. 94HA6CUE
The command I use is:

Quote:hashcat.exe -m 2500 -a 3 -w 3 upc.hccapx --session testmoj --increment --increment-min 8 --increment-max 8 -o wynik3.txt -1 ?u?d ?1?1?1?1?1?1?1?1  --force

The number of combinations is over ~ 2.8 trillion = approx. 10 years.

I would like to reduce the number of combinations knowing that the password contains:

1. min. 3 - 4 numbers (?d) [e.g. ok - 94HA6CUE-?d?d?u?u?d?u?u?u ; 94HA6CU6-?d?d?u?u?d?u?u?d / nok - A4HA6CUE-?u?d?u?u?d?u?u?u ;  94HA6C56-?d?d?u?u?d?u?d?d]

2. min. 4 - 5 letters (?u) [e.g. ok - 94HA6CU6-?d?d?u?u?d?u?u?d ;  94HA6CUE-?d?d?u?u?d?u?u?u / nok - 94HA6C56-?d?d?u?u?d?u?d?d ; A4HA6CUE-?u?d?u?u?d?u?u?u]

3. not more than 3 same numbers (?d) and letters (?u) [e.g. ok - 995A9CUE-?d?d?d?u?d?u?u?u ; 995A9CAA-?d?d?d?u?d?u?u?u / nok - 999A9CUE-?d?d?d?u?d?u?u?u ; 99AA9CAA-?d?d?u?u?d?u?u?u]

4. not more than 3 numbers next to each other (?d) [e.g. ok 946ABCUE-?d?d?d?u?u?u?u?u / nok - 9462ACUE-?d?d?d?d?u?u?u?u ; AHHA6956-?u?u?u?u?d?d?d?d]

5. not more than 2 same numbers (?d) and letters (?u) next to each other [e.g. ok - 99HA6CUE-?d?d?u?u?d?u?u?u ; 99HA6CUU-?d?d?u?u?d?u?u?u / nok - 999A6CUE-?d?d?d?u?d?u?u?u ; 99HA6UUU-?d?d?u?u?d?u?u?u]

For the above, I use the command:

Quote:mp64.exe -q 4 -r 5 -1 ?u?d ?1?1?1?1?1?1?1?1 | hashcat.exe -m 2500 -a 3 -w 3 upc.hccapx --session testmoj --increment --increment-min 8 --increment-max 8 -o wyniki3.txt -1 ?u?d ?1?1?1?1?1?1?1?1 --force

The question is:

1. What will the correct mask command look like with my rules? Can someone write it to me and explain it?
2. What am I doing wrong and why are my commands not working?

I read the hashcat wiki tutorial, but I still can't quite understand everything because my English is poor...

I am asking for help because I have been working on it for the second week and I do not have the strength to do it...

Thank you

Hi,

I used --force because my device has unstable OpenCL driver.

If i run command:

hashcat-6.1.1>mp64.exe -q 4 -r 5 -1 ?u?d ?1?1?1?1?1?1?1?1 | hashcat.exe -m 2500 -a 3 -w 3 upc.hccapx --session testmoj -o wyniki3.txt

I get the answer:

Quote:hashcat (v6.1.1) starting...

* Device #1: Unstable OpenCL driver detected!

This OpenCL driver has been marked as likely to fail kernel compilation or to produce false negatives.
You can use --force to override this, but do not report related errors.

No devices found/left.

By adding command --stdout:

Quote:mp64.exe -q 4 -r 5 -1 ?u?d ?1?1?1?1?1?1?1?1 | hashcat.exe --stdout -m 2500 -a 3 -w 3 upc.hccapx --session testmoj -o wyniki3.txt

Invalid mask length (0).

Where is the error and what did I do wrong?

Thanks for the help.

Fix your setup first.

Hi,

I solved the problem with the OpenCl drivers.

I run my command:

mp64.exe -q 4 -r 5 -1 ?u?d ?1?1?1?1?1?1?1?1 | hashcat.exe -m 2500 -a 3 -w 3 upc.hccapx --session testmoj -o wyniki3.txt

Why is nothing happening? Where did I go wrong?
Any suggestions?

Thanks for the help.

When you use stdin you must use attack mode 0. Also, progress will not be available as hashcat has no information about the external program generating candidates.
