Hashcat exiting with no error message

[-=bb=-]

Quick Update

Checking the errorlevel by using 'echo %errorlevel%' gave me an errorlevel of 9009.

Apparently 9009 can mean a file not found error, so I ran ProcMon to see if I could figure out what the missing file was. Whilst I couldn't see a missing file, I did notice that WerFault.exe was being called.

Checking the Event Viewer (which I have no idea why I didn't do sooner) showed me the following error

Code:

Faulting application name: hashcat64.exe, version: 0.0.0.0, time stamp: 0x5bd5e68a Faulting module name: igdrcl64.dll, version: 21.20.16.4664, time stamp: 0x58fa2e54 Exception code: 0xc0000005 Fault offset: 0x00000000004609c0 Faulting process ID: 0x8ec Faulting application start time: 0x01d487e9e95cad36 Faulting application path: C:\Users\xxxxx\Desktop\HashCat5.0\hashcat64.exe Faulting module path: C:\WINDOWS\System32\DriverStore\FileRepository\ki122581.inf_amd64_39d9112bbe77f060\igdrcl64.dll Report ID: c059468e-ef4c-4d9a-89df-07ad67bc27c2 Faulting package full name: Faulting package-relative application ID:

idgrcl64.dll is the Intel Graphics Driver. The DriverStore version was old so a reinstall of the Intel HD Graphics driver appears to have solved the problem.

Lessons learnt :

1. Check Event Viewer when troubleshooting
2. Just because you're running hashcat on the nVidia chipset, the Intel one can still ruin your day

Hopefully the troubleshooting steps outlined may help someone else but we can mark this as solved now.

Happy cracking!
