Exhausted? - Toil - 12-24-2012

When I'm running this command:

./hashcat-ocl-64.bin -c 500 --gpu-accel 160 --gpu-loops 1024 -n 800 --remove -m 0 uncracked.txt -o cracked.txt -a 3 -1 ?l?d?s?u?h ?1


I get;


Status.......: Exhausted
Input.Mode...: Mask (?1)
Hash.Target..: File (uncracked.txt)
Hash.Type....: MD5

I'm using a 7970, and it works with wordlists, etc, and other masks, with other hash lists.

Any idea why it's happening?


Thanks

You set 1 byte long mask (?1) and hashcat exhausted all 157 available password variations. You should supply longer mask (?1?1 and so on), also check for -i flag

I know about the --increment flag.
It doesn't work as expected. You can't custom set your ?1, ?2, ?3, ?4. It is always ?l?d?u.

But, what does it mean "exhausted"
Finished?

Thanks

RE: Exhausted? - The Mechanic - 12-24-2012

Exhausted means all password combinations you provided have been tried, expand your mask. -1?l?u?d = ?1?1?1?1?1?1?1?1?1?1 = 10 length max lower, upper, digit

-1?l?u -2?l?d -3?d?s ?1?2?2?3?3?3 is 6 length max, would be lower upper char for first position, 2nd and 3rd is lower and digit 4,5,6 positions would be digits and symbols.

Use the increment flag to run all combinations of the mask up to the length you provide or specify no mask and use the build in set

false.

yes, it means you have exhausted the given keyspace without finding the password.

Yes, you're doing it wrong.

1st, your commands are ugly, stack them properly.
2nd, your use of the -c parameter with a brute-force attack is extremely ignorant.
3rd, since you haven't provided any mask in the first attack, -plus uses the default masks and that's why your hash wasn't cracked.
4th, in the second attack you added a mask "?1?1?1?1" which fits your password, that's why it's cracked.
