Need help with mask attack on OSX - oberhans - 09-19-2016

Hey there.

For several days now I try to solve a geocaching puzzle (which I'm almost certain uses a sha1 hash) with the help of hashcat but all I can get is "Exhausted" as a result.

Can you tell me what I am doing wrong please?

So this is my command (of with I already tried dozens of variations):

Code:
hashcat -m 100 -a 3 -o found.txt --custom-charset1=5678 --custom-charset2=123456 sha-1.txt "N 49 2?1.?d?d?d E 011 0?2.?d?d?d" --potfile-disable

In sha-1.txt is a single line with this hash:

Code:
0e9bfe8f349ed4b75d480743d1ab55e6e83c8176

And that is the result:

Code:
OpenCL Platform #1: Apple

All I can seem to get is "Exhausted" status even if I change the mask, post the hash directly into the command, use a .hcmask file and so on. Is there an error in my command – or is something wrong with the OSX implementation?

Thanks and regards!

"Exhausted" mean that all combinations of given charset was checked with no match (in other words job done 100% and password didnt found )

But it can impossibly be done in 5 seconds ... or can it?

The keyspace is only 24000000.

As I am quite new on this: What does this actually mean? Is my mask wrong?

RE: Need help with mask attack on OSX - kiara - 09-21-2016

it means that for this hash 24,000000(24 mil) is nothing while u do 21651.7K (u finished the attack in 5 sec..)
hashcat tried all the 24mil "passwords*" and did not find any that belong to that hash
