illegal hardware instruction - JuanPelota - 05-12-2021 Hello, I have made a USB disk with a persistent The-Distribution-Which-Does-Not-Handle-OpenCL-Well (Kali). I managed to boot on it on a forgotten computer at my job. Unfortunately hashcat don’t run on it. It doesn’t initialize the backend and says : illegal hardware instruction. I am not a tech guy. Is it possible that a CPU/computer is restrained through some kind of hardware setting ? Thanks RE: illegal hardware instruction - Snoopy - 05-12-2021 (05-12-2021, 11:02 AM)JuanPelota Wrote: Hello, see https://hashcat.net/forum/thread-10074.html i dont think, that hashcat runs without proper drivers / setup inside a live distribution (basic drivers), you could try to install/setup (pocl, cuda or something else needed) due to your usb-persistence but i dont expect that hashcat will run fluid RE: illegal hardware instruction - JuanPelota - 05-12-2021 (05-12-2021, 03:12 PM)Snoopy Wrote: [quote="JuanPelota" pid='52565' dateline='1620810133'] Ok I see, so maybe The-Distribution-Which-Does-Not-Handle-OpenCL-Well (Kali) was not a good starting point ? I just followed an advice since I don’t know shit in this world just learning and playing around to recover an old wallet like so many fellow noobs. The CPU on the computer is an Intel Pentium G4400 with Open CL 1.2. I guess this is not a super classic one ? RE: illegal hardware instruction - Snoopy - 05-12-2021 well, using live distributions and/or vms is more likely the problem due to driver problems / hardware restrictions just for "testing" or to see if you can manage to start the attack, a precompiled windows binary of hashcat would be the best starting point, even with a more or less actual laptop cpu (intel cpu) hashcat will most likey just run out of the box (if opencl drivers are installed) bruteforcing will be resultin in "forget it" (any CPU) but if you have a wordlist of your passwords used you may be able to recover your pw RE: illegal hardware instruction - JuanPelota - 05-12-2021 (05-12-2021, 03:41 PM)Snoopy Wrote: well, using live distributions and/or vms is more likely the problem due to driver problems / hardware restrictions Thanks for your help. On this PC the windows binaries don’t work either. With -I it shows only the Nvidia GPU and no CPU info. I have nevertheless tried to force to another device (to use the CPU) with -D without success. So it’s game over for this machine. RE: illegal hardware instruction - Snoopy - 05-12-2021 if it dont show the cpu with -I then the opencl runtime is missing (you can download it from intel, the last version i found in my download folder opencl_runtime_18.1_x64_setup.msi RE: illegal hardware instruction - JuanPelota - 05-12-2021 (05-12-2021, 03:41 PM)Snoopy Wrote: well, using live distributions and/or vms is more likely the problem due to driver problems / hardware restrictions Thanks for your help.
