crack excel password with hashcat, possible? - tedmosby111 - 06-29-2017

There is an old worksheet with a password on it. Now, I can't remember the password and forgot to write it down. Is it possible to crack the password with Hashcat? If yes, how to do that?

Thanks for the suggestion. The tutorial is a bit short. I open the .py file and still don't know how to get it running.

Code:
python office2hashcat.py the_path_to_your_excel_file_here.xls > hash.lst

Code:
./hashcat64.bin -a 3 -w 3 -m 9800 hash.lst -i --increment-min=4 --increment-max=8 -1 ?l ?1?1?1?1?1?1?1?1

Thanks. How long it would take to crack the password? It runs for 2 days and still not find the password.

P.S. it takes too much time with hashcat. maybe i got it wrong. Finally, I followed this guide to crack the password in less than 24 hours.

Maybe it does not have the length 8. I'd try wordlists first.
