Not finding my own set password - LoZio - 12-14-2018
Hi, I'm working on a Office 2013 file and I'm pretty sure I have the correct password in my dictionary, but after hours spent cracking I get no results. So I did a pretty simple test: I created a Word document, applied the procedure to encrypt it with passpass as password, extracted the hash with office2hashcat (or office2john is the same) and tried:
- a simple wordlist of 10 password, containing also passpass
- a bruteforce session for passpas?l
Both end with no success, even if the password is there for sure.
Using 5.10 on Win as:
hashcat64.exe -a 0 -m 9600 \Work\test.hsh \Work\test.txt
or
hashcat64.exe -a 3 -m 9600 \Work\test.hsh passpas?l
The hash was obtained as:
$office$*2013*100000*256*16*8b35c1c9d47628bcd8e6fd3225c7a816*56f7f0f311080fe61fef145f14072971*221e2a3a0957a92021da211700d3ea44ca7759f9f1b1e56c2acc7ea308ea52f4
I think I'm doing somethign horribly wrong, but can't find what it is. Anyone who can help me?
Thanks

a 3 = mask, but you give wordlist?
a 0 = wordlist, but you give mask?
If I try "hashcat -a 3 -m 9600 lozio.txt passpas?l" I get $office$*2013*100000*256*16*8b35c1c9d47628bcd8e6fd3225c7a816*56f7f0f311080fe61fef145f14072971*221e2a3a0957a92021da211700d3ea44ca7759f9f1b1e56c2acc7ea308ea52f4:passpass
RE: Not finding my own set password - vagantis - 12-14-2018
Well, use -a 3 for mask attack and -a 0 for wordlist not the other way around

I just typed them wrong, I was using the correct syntax (it does not even start using the wrong one).
I corrected the first post to avoid unuseful answers.
You get the right result, I end up with 0/1 found...

RE: Not finding my own set password - LoZio - 12-14-2018
Just found a possible clue. Using benchmark mode with -m 9400 I get the test done. With -m 9600 I get:
Device #3: ATTENTION! OpenCL kernel self-test failed.
If I force the device to the Intel GPU (that is normally discarded saying the OpenCL runtime is broken) I found the password.
So basically using the AMD GPU (latest driver as of today) seems to work, but finds no password.
Weird tihng is that the problem is with that specific algo (9600) and not with others (9400).
RE: Not finding my own set password - DanielG - 12-14-2018
okay, so you typed them instead of copy/paste from your commandline, are you sure you aren't forgetting something else? like perhaps you are using --force? or other options? And hashcat does not show any errors in the beginning when running "hashcat64.exe -a 3 -m 9600 \Work\test.hsh passpas?l"?
Just making sure because otherwise you will get more unuseful answers.

I was using a remoted shell from my mobile, not so easy to cut & paste.
BTW I used another machine with a proper console and a Quadro GPU on it, used the same hash and here is the complete session, again password was not found:

The wordlist or mask that you are using is too small.
This means that hashcat cannot use the full parallel power of your device(s).
Unless you supply more work, your cracking speed will drop.
For tips on supplying more work, see: https://hashcat.net/faq/morework
Approaching final keyspace - workload adjusted.
Cracking performance lower than expected?
* Append -w 3 to the commandline.
This can cause your screen to lag.
* Update your OpenCL runtime / driver the right way:

* Create more work items to make use of your parallelization power:

I am guessing the issue relates to the mask, somehow. That mask is only 8 char long, yet you have as 9 chars

Sharp eye. You're right, should be 8. Eventually the "?" is not the real 7 bit "?" character but something that looks similar.
