hashcat Forum

Hi,

I need to unlock a few old excel files and I chanced into hashcat by reading this article:
https://pentestcorner.com/cracking-micros...h-hashcat/

Follow through the steps mentioned but kept getting the "Failed to parse hashes using the 'native hashcat' format." error.

Command I use:

hashcat64.exe -a 0 -m 9700 --username -o found.txt hash.txt pass.txt

I have no clue regarding the password or the version of the Excel file is.

Please help. Heres the entire message that I got:

Sounds like the hash isn't in the expected format. If you try the exact same attack on the example 9700 hash here:

https://hashcat.net/wiki/doku.php?id=example_hashes

... does your attack work? If so, the problem is the format of the hash itself. If you post it (with most of its random-looking alphanumeric characters masked with "X"), the format might be identifiable.

I have stumble upon the password of the files so I will close this thread.

However I have another question in which I will open in another thread.
