Hash of office file need to be cracked. - katzenjaeger - 10-07-2019

Dear friends,

at first I want to apologize for my poor english.

Maybe somone can help me or can give a good advice.

I friend of mine send me a encrypted office file with a story inside. It's kind of challange.

I extracted the hash with office2john. Now I need to crack the hash to get the story.

I run hashcat with the string:

Code:
hashcat -m 9600 -o cracked -r /usr/share/oclHashcat/rules/best64.rule officepassword

What I get is:

Code:
OpenCL Platform #1: The pocl project
====================================
* Device #1: pthread-AMD Phenom(tm) II X4 965 Processor, 2048/4470 MB allocatable, 4MCU

Bitmaps: 16 bits, 65536 entries, 0x0000ffff mask, 262144 bytes, 5/13 rotates

* Zero-Byte

ATTENTION! Read timeout in stdin mode. The password candidates input is too slow:
* Are you sure that you are using the correct attack mode (--attack-mode or -a)?
* Are you sure that you want to use input from standard input (stdin)?
* If so, are you sure that the input from stdin (the pipe) is working correctly and is fast enough?

I assume, that the mistake is on my side. Kann someone help? Where I did the mistake, how I can go further?

With best regards
