hashcat stops after about 37 minutes - patpro - 07-27-2017

Hi,

I've got a large number of hashes and for each one I've got a very serious candidate that just need some mask added to get the real password.
So I've made a script that launch hashcat with my candidates (base word + case toggle) against all hashes that share the same "candidate".
The command looks like this:

Code:
./hashcat64.bin -a 6 --increment -m 120 "/foo/bar/hc-tmp/${f}.h" "/foo/bar/hc-tmp/${f}.wl" -1 ?l?u?d ?1?1?1?1?1?1 --potfile-path=/foo/bar/bouclehc.pot --status --status-timer=60 -w 4

Things go smoothly, at least until I reach an increment that brings time above 37 minutes. Strangely, hashcat will just end the session when it reaches about 37-38 minutes. It means it won't finish the last mask (?1?1?1?1?1?1).
Here are two examples:

The script runs in a screen, and is basically a while true loop.

Any idea why hashcat would abort the session after about 37-38 minutes each time?


RE: hashcat stops after about 37 minutes - patpro - 07-27-2017

Some precision: usually I can make long sessions of hashcat without any problem (several weeks), but I don't usually use -6 mode.
A quick & dirty log analysis shows this timing:
Code:
37.9167
38.8333
37.9167
42.8
37.8167
37.9833
38.0667
38.0833
38.0667
38.5333
No error, nothing special (neither in hashcat.log nor in syslog/dmesg/...)

Please retry with hashcat v3.6.0 release version


RE: hashcat stops after about 37 minutes - patpro - 07-28-2017

Hi atom,
I'm already running v3.6.0


RE: hashcat stops after about 37 minutes - philsmd - 07-28-2017

Did you try to run the commands without the for/while loop?
Does the problem also happen without the loop, e.g running the commands one after the other?


RE: hashcat stops after about 37 minutes - patpro - 07-28-2017

I'm currently running the same command outside of a loop, and so far so good: it ran 4 hours on 5 char long mask, and the 6 char mask is running for 2 hours now.
Can't get why hashcat inside a while loop would end spontaneously well before exhaustion…


RE: hashcat stops after about 37 minutes - patpro - 07-28-2017

Ok, so after a while (4 hours) the "out of the loop" command eventually stopped too, well ahead from schedule. Here are the 3 last status printed on screen:

RE: hashcat stops after about 37 minutes - philsmd - 07-29-2017

Does the problem also happen without the --increment command line option?
