Wpa/Wpa2 dictionary attack is very slow after the latest update - Virgula - 02-22-2018 after the latest updates (current version: 4.0.1) I saw that the brute force speed is slower than before... Example.... I use hash cat utils to convert .cap to hccpax and devices available are the following: OpenCL Platform #1: Apple ========================= * Device #1: Intel(R) Core(TM) i7-3635QM CPU @ 2.40GHz, skipped. * Device #2: HD Graphics 4000, 384/1536 MB allocatable, 16MCU * Device #3: GeForce GT 650M, 256/1024 MB allocatable, 2MCU Now... the devices speeds are very lower than before, example: now: Speed.Dev.#2.....: 2345 H/s (5.11ms) Speed.Dev.#3.....: 4944 H/s (5.10ms) Speed.Dev.#*.....: 7286 H/s but before the update (to 4.0.1) speed was about (I don't remember precisely): Speed.Dev.#1.....: 3500 H/s Speed.Dev.#2.....: 5800 H/s Speed.Dev.#3.....: 16890 H/s The time for a dictionary attack or brute force was increased so much. Why now Is slower than before for no apparently reasons? How can I resolve? Thank you RE: Wpa/Wpa2 dictionary attack is very slow after the latest update - undeath - 02-22-2018 current version is 4.1.0 https://github.com/hashcat/hashcat/releases/download/v4.1.0/hashcat-4.1.0.7z RE: Wpa/Wpa2 dictionary attack is very slow after the latest update - Virgula - 02-22-2018 I updated it automatically through brew on osx RE: Wpa/Wpa2 dictionary attack is very slow after the latest update - undeath - 02-22-2018 so, are you on version 4.1.0 yet?

I successfully updated hashcat to 4.1.0 but crack speed is still lower than before Speed.Dev.#2.....: 2400 H/s (5.69ms) @ Accel:4 Loops:2 Thr:512 Vec:1 Speed.Dev.#3.....: 3919 H/s (8.06ms) @ Accel:16 Loops:4 Thr:1024 Vec:1 Speed.Dev.#*.....: 6319 H/s RE: Wpa/Wpa2 dictionary attack is very slow after the latest update - soxrok2212 - 02-22-2018 You may want to try with -w 3 or -w 4... dunno how the optimized kernels will perform on old cards like those. Code: hashcat -m 2500 cap.hccapx dictionary.txt -w 3 Or try adding -O for optimized kernels, I don't recall if optimized kernels are used by default in an actual run, though they are in a benchmark.

Code: hashcat --session hashcat --restore -w 4 -O Speed is the same... It was about 16000 H/s but.... Speed.Dev.#2.....: 3080 H/s (9.86ms) @ Accel:8 Loops:2 Thr:512 Vec:1 Speed.Dev.#3.....: 3906 H/s (7.60ms) @ Accel:16 Loops:4 Thr:1024 Vec:1 Speed.Dev.#*.....: 6985 H/s RE: Wpa/Wpa2 dictionary attack is very slow after the latest update - Virgula - 02-22-2018 EDIT: Code: hashcat -m 2500 net.hccapx /dict -w 3 --session different Speed.Dev.#2.....: 3345 H/s (74.82ms) @ Accel:16 Loops:8 Thr:512 Vec:1 Speed.Dev.#3.....: 4717 H/s (49.27ms) @ Accel:32 Loops:16 Thr:1024 Vec:1 Speed.Dev.#*.....: 8062 H/s But my computer now lags a little and before not and the speed was 16.000 H/s not 8.000!.... I don't understand... maybe problem is due to latest Osx o.s updates...

It killed my AMD speeds, not sure about nvidia though. Might be worth your time opening a bug on GitHub.
