hashcat Forum

Hello everyone

I just tried to crack an WPA hccapx file with hashcat but I got this

Code:
Crunch will now generate the following amount of data: 17575569559640669184 bytes

Sorry for my English I'm french Smile

Thx for your help

1. why do you use crunch ?
2. why do you use hashcat 5.1.0 if hashcat 6.0.0 is available (https://hashcat.net/hashcat/) ?
3. what is your command ?
4. why don't you give your full specs ? if the error says "out of host memory" , you should at least specify how much RAM you have

Thank you for your answer
I will answer each of your questions

1. I use crunch to create a wordlist with all the passwords that I will test with hashcat on the file
2. Idk I just do "apt-get install hashcat" today and this is the version that was installed
3. the command is "crunch 10 20 abcdefghijklmnopqrstuvwxyz0123456789 | hashcat -m 2500 -d 2 file.hccapx"
4. I got 16GB RAM and 8GB VRAM

- you should download hashcat directly from https://hashcat.net/hashcat/
- don't use crunch, use this instead:

Code:
hashcat -m 2500 -a 0 -w 3 -r my.rule -d 2 file.hccapx dict.txt

where my.rule is a rule file like the ones in rules/ folder , but that doesn't shorten the passwords to < 8 characters
where dict.txt is a dictionary file that does contain very likely/good password candidates

This makes sense, because WPA/WPA2 has a minimum password length of 8 chars/bytes and brute-forcing (trying all these different characters) a password that is 10+ characters long is infeasible (not possible, even with a lot of GPUs)

If that command still doesn't work, try to see if a benchmark works:

Code:
hashcat -m 2500 -b

I inquired and found that hashcat 6.0.0 is only available on the latest version of ubuntu (20.10) . I update my computer and test everything

Solve !
I updated my computer to get the latest version of hashcat.
Many thanks to philsmd

Excellent!

(And just for the record, you can download hashcat 6.0.0 and run it on older versions of Ubuntu)
