hashcat Forum

Anybody can explain this low utilisation? 10x.

First thing, it's a raw wordlist attack, those tend to have lower speeds/utilisation than mutation / brute force attacks.
Second, I can see that the cache is set to default (32MB), which is why the wordlist is split to 234 segments, which is why the utilisation is low.
Try increasing the cache (-c) flag.

And please use an expressive thread title if you have a question, "HC" can simply mean anything.
