Why Is Hashcat Soooooo Slow
#1

Howdy All,

I am trying to crack an iTunes backup file for a friend that swears black and blue he never set a password on it. Unfortunately it contains all the photos,videos of his new born Sad 

I am running the following command.
hashcat hash.txt -m 14800 -a 6 dict.txt ?d?d?d?d --session 4Digits

I have prepared a word list of all his common passwords in the various combinations uppercase, lowercase, sentence case, reverse sentence case etc and this is saved in dict.txt. 

I am running it on my MAC mini and it is slow as hell! I thought this was because it only has an embedded Intel HD Graphics 4000. I created a Nv6 VM in Azure which runs the Nvidia Tesla card and loaded the GRID drivers and still the speed was slow extremely slow (a 90 day attack dropped to 30 days). 

When I start HashCat it states the following 

Filename: dict.txt
Password: 24
Bytes:163
Keyspace: 240,000


The wordlist or mask that you are using is too small. 

It doesn't seem to matter what I do to the mask or word list it still throws the wordlist too small error. According to hashcat.net/faq/morework I am suppose to use rules? 

./hashcat64.bin --stdout wordlist.txt -r rules/best64.rule | ./hashcat64.bin -m 2500 test.hccapx

What I can't figure out is which rule I am suppose to use? I presume my command would look something like
hashcat --stdout dict.txt -r rules/somerule | hashcat -m 14800 -a 6 ?d?d?d?d hash.txt --session 4Digits

I have read and reread the morework faq but I find it very confusing and can't work out if the speed is because the algorithm is simply slow or if it's because my word list is quote small (just 24 words) which I would have thought would made it faster and simpler to crack. 

Any help would be greatly appreciated. 

Thanks,
Chipper
