Need help using Hashcat - Dametceci - 02-10-2022
Hi
I am requesting the help of the commuity if possible
I am very new at this and have a very specific use case currently.
I need to find my xlsx password that is 1 year old and would like to have this rule :
- Having one or two word in the password (is must be a complete word in the dictionnary)
- having possible numbers at the beginning of the first word, or in between of the two words on at the end
- Having capital letters
- Having from 6 to 15 caracteres
What would you recommend I write in the command?
Thank you very much

I think that no one can help you in this case
You have to do it on your own

I am not gone spoon feed the answer, but these are the general steps or workflow that I would use
0) Extract the hash
https://hashcat.net/wiki/doku.php?id=frequently_asked_questions#how_do_i_extract_the_hashes_from_office_word_excel_etc_documents
1) Get an English Dictionary, assuming it is english, or use your own dictionary:
https://github.com/dwyl/english-words/
2) Search 'how to filter words on length using SED":
https://askubuntu.com/questions/649820/filter-lines-based-on-length-using-sed-and-grep
3) What you describe would best done using hybrid attacks to generate the word-digit combinations
Hence, you have to break it down, first use a hybrid attack for a [d] [word], [dd] [word] [word][d] [word][dd]
Read here more about hybrid attacks, output the passwords with the option --stdout:
https://hashcat.net/wiki/doku.php?id=hybrid_attack
You will end up with a lot text files for each option.
4) Combine the files, into all_words.txt
cat word.txt > into all_words.txt
cat word-d.txt > into all_words.txt
cat word-dd.txt > into all_words.txt
cat d-word.txt >into all_words.txt
cat dd-word.txt >into all_words.txt
5) Use a combinator attack, basically use the word list twise
./hashcat64.bin -m 1 -a 1 hash.txt all_words.txt all_words.txt -w3
Good luck, there are different ways to do it but this should help get you started.
