Mask-attack problem - yap9911 - 11-12-2021
Hi, i am new to hashcat and i am trying to crack a password of a doc file using mask-attack but it doesnt work. Any problem with my command?
the hash is: $oldoffice$3*80XXX422XXbXXXb39356bXXXbXXc0053*8XXXXdf4XX106XXXX243204c76XXXXb1*Xe0c1XXXXa029c33570XXXXba724XXXX05fdc1XX
the password should be 57913
here is the output of my cmd:
C:\Users\Dell\Downloads\hashcat-6.2.4>hashcat -m 9800 -a 3 hash1.txt ?d?d?d?d?d
