Efficient Password Cracking

Sometimes you end up with a great many Windows domain passwords that need cracking – either because you have compromised the domain controller and exported them yourself, or because the client has asked you to perform a password audit and has supplied the database to you themselves.

As you know, LM hashes are insecure, and there is a very good way of cracking these (Ophcrack). However, there will also be passwords that cannot be cracked using the standard tables, or maybe the LM hash is not present in the dump at all. In this case, we’ll need to attack the NTLM hash with another tool – in this case a GPU cracker known as Oclhashcat.

In this case we have a large (something like 6,000 entry) pwdump format file, with LM and NTLM hashes. Because the LM hashes have various weaknesses in the cryptography, we can crack a lot of passwords using Ophcrack – but in some cases only NTLM hashes are present. In this case we can use a hybrid approach.

  1. This way my acquaintance Wesley Virgin's biography launches in this SHOCKING AND CONTROVERSIAL VIDEO.

    You see, Wesley was in the army-and shortly after leaving-he discovered hidden, "mind control" tactics that the CIA and others used to get everything they want.

    THESE are the exact same secrets many celebrities (notably those who "come out of nowhere") and the greatest business people used to become rich and successful.

    You probably know that you only use 10% of your brain.

    That's because most of your brainpower is UNCONSCIOUS.

    Maybe this conversation has even taken place INSIDE OF YOUR very own head... as it did in my good friend Wesley Virgin's head 7 years ago, while riding a non-registered, beat-up garbage bucket of a car with a suspended driver's license and on his banking card.

    "I'm absolutely fed up with going through life paycheck to paycheck! When will I finally make it?"

    You took part in those types of questions, isn't it so?

    Your success story is going to happen. All you have to do is in YOURSELF.

    WATCH WESLEY SPEAK NOW
