  8. @Null Byte Hi, i've done a similar video a few days ago, and just now. Using a password on an excel doco, using the "password" as Password, it cracked it straight away using hashcat & the rockyou wordlist, I made another word doco using Password1, it cracked it, however it failed to crack a 3rd word doco using Password123, have you tested with a stronger password? I notice the amount of hashes it sends was a lot less, than NTLM for e.g. Office hashcat (Speed.#2………: 267 H/s (4.75ms) @ Accel:256 Loops:128 Thr:1 Vec:8)
    NTLM the H/s is well into the thousands… I've also tried this with a Rule, and it still doesnt crack it, I left it overnight, it ran for 16hrs, nothing… Have you or anyone else tried a more complex password, something similar to what you can crack as an NTLM Password? For e.g. if your NTLM Hash is Password123, and you use hashcat to crack it with the rockyou wordlist, you know its gonna crack it – however using the same Password123 on Office2013 ($office$*2013*100000*256*16*4dfca6499f872b7005653d9b1861e0a9*9f5b5d190a3e2b37a6f0dc908e72b2cd*12974a30eb842a9a9f8b6c7d7627fc2c1a85e2949bc1d1441c8eb0499025487a) it still doesnt crack… would be good to see if someone else has come across this, thanks.

  37. Lets say I have every bit of information about the document. cipherAlgorithm, hashAlgorithm, BitSize, KeySize, The CBC Spin count, the hash, the salt, and the key hash. Can any of these variables be put into hashcat to speed up cracking? All of these variables are stored in plain text of the document called "EncryptedInfo" if you open the document with 7zip.
