To crack hashes we first need to obtain them. We will download and use in the tutorial the wordlist 2 that contains words taken from Wikipedia.įig 4: Select good wordlists to download.

Press alt+d+h to open Hash Suite Downloader and select some wordlist(s) to download (fig 4) (Tip: In Hash Suite, pressing F1 shows a context sensitive help, so if you do not know how to do something simply press F1 and read the documentation). Next we need to obtain some big/quality wordlist. In other cases experiment with values ranging from the maximum value to 0.If using an integrated GPU from Intel, put Threads to the maximum value (Logical cores).If the GPUs performance is orders of magnitude higher than the CPU's, reduce Threads by the number of GPUs (our case).The general rules to configure this setting are: You may need to manually configure Threads by pressing alt+h+t (fig 3) to obtain the best performance when CPU and GPU are used concurrently.įig 3: Hardware Tab. This is the best setting for our hardware. Hash Suite automatically selects Threads=3 (of 4), which means we dedicate 3 CPU cores to hashing and 1 CPU core to GPU communication. The benchmark lasts ~12 minutes (and you may stop it whenever you want) on our system composed of one CPU (Core i5-4670) with a high-end gaming GPU (GeForce GTX 970). We will use these shortcuts heavily in the tutorial. Hash Suite uses a ribbon interface that supports hierarchical keyboard shortcuts. Press alt+f+b to run a quick benchmark (fig 2). First we will run a benchmark to know our hardware performance. Let’s do some preparations before we begin to crack passwords. Press Enter or click the OK button to dismiss. The Welcome dialog (fig 1) appears at first run with some basic information.

When the download completes unzip the file and execute Hash_Suite_64.exe (this executes the 64 bits version that is faster than the 32 bits). Purchase it or you can download the free version. Rules are common transformations to base words that many users make to form passwords (for example, the word "love" might result in a password of "Love12"). Hash Suite also supports rules that can be applied to all key-providers.

LM2NT: Alters the case of characters in cracked LM hash passwords to instantly crack the corresponding NTLM hash passwords.DB Info: Generates keys taking all usernames/found passwords.Phrases: Generates phrases combining words from a wordlist.Keyboard: Generates keys trying combinations of adjacent keys on a keyboard.Very successful and requires low resources. Wordlist: Generates keys taking them from a dictionary.

Another reason why this approach is so very effective is that Windows uses password hash functions that are very fast to compute, especially in an attack (for each given candidate password). This approach works because users generally select passwords that are easy to remember, and as a side-effect these passwords are typically easy to crack. It follows the same procedure used by authentication: it generates different candidate passwords (keys), hashes them and compares the computed hashes with the stored hashes. Hash Suite, like all other password hash crackers, does not try to "invert" the hash to obtain the password (which might be impossible). To authenticate a user, the password presented by the user is hashed and compared with the stored hash.

This hash function is one-way in the sense that it is infeasible to infer a password back from its hash, except via the trial and error approach described below. To reduce this danger, Windows applies a cryptographic hash function, which transforms each password into a hash, and stores this hash. Storing user passwords in plain text naturally results in an instant compromise of all passwords if the password file is compromised.

This tutorial was written using Hash Suite 3.4 Pro and assumes basic knowledge of password hashing and password hash cracking.
