Hello I installed hashcat on a

#lspci -s 00:2
00:02.0 VGA compatible controller: Intel Corporation HD Graphics 620 (rev 02)

And get first something about Intel's OpenCL runtime being broken (which I don't know if its true)

Code: Select all

$ hashcat -m 2500 net.hccapx rockyou.txt  
hashcat (v5.1.0) starting...

* Device #1: Intel's OpenCL runtime (GPU only) is currently broken.
             We are waiting for updated OpenCL drivers from Intel.
             You can use --force to override, but do not report related errors.
No devices found/left.

Using Force it fails the kernel-self-test:

$ hashcat -m 2500 net.hccapx rockyou.txt  --force

Rules: 1

Applicable optimizers:
* Zero-Byte
* Single-Salt
* Slow-Hash-SIMD-LOOP

Minimum password length supported by kernel: 8
Maximum password length supported by kernel: 63

Watchdog: Hardware monitoring interface not found on your system.
Watchdog: Temperature abort trigger disabled.

* Device #1: ATTENTION! OpenCL kernel self-test failed.

Your device driver installation is probably broken.

Aborting session due to kernel self-test failure.

You can use --self-test-disable to override this, but do not report related errors.
