Crack Lm Hash Nt Hash Decrypt

Have you ever find an interesting hash on Internet or in some old database that used to be not so secure ? Now, with awesome and broad web services that you can find on the internet, you may be able to know what that hash used to look before it were hashed by some hasher algorithm like MD5, SHA1 or GOST.

In Kali Linux, you may boost the process of searching on internet for the original string of your hash using the findmyhash tool that will do the job for you. findmyhash is an useful python script used to crack a lot of hashes using web services.

How does findmyhash works ?

findmyhash is an awesome command line utility that cracks hashes through different online services. As you may know, functions like MD5 aren't plainly encryption tools (though it may be used as part of some encryption algorithms) but a one way hash function, that means that you can't reverse it with certainty.

Both types of hashes generate a 128-bit stored value. Most password crackers today crack the LM hash first, then crack the NT hash by simply trying all upper and lower case combinations of the case-insensitive password cracked by the LM hash. The LM hash is a very weak one-way function used for storing passwords. In the 'Add NT Hashes from' box, accept the default selection of 'Import Hashes from local system', as shown below, and click Next. The password hashes appear, as shown below. Understanding Password Hashes There are two password hashes: LM Hashes and NT hashes. LM hashes date from the 1980's, and are so weak Microsoft no longer uses them.

I have a number of LM hashes that I have been attempting to crack with hashcat. My understanding was that LM splits passwords into two separate 7 character strings before they are hashed. I also believe that they only use uppercase letters, as well as digits and special characters.

Basically what it does is to send the hash that you provide to different web services and in case that some database of any of the available services contains the string that generates the hash that you provide, then you'll get the original string (which using the specified hasher function would generate the hashed string) as result.

findmyhash is included on Kali Linux and can be used quickly from the command line.

Using findmyhash

The usage of findmyhash is pretty simple, it has 1 required argument (the name of the hasher function e.g MD5, SHA1 etc) and 3 options:

-h <hash_value>: If you only want to crack one hash, specify its value with this option.
-f <file>: If you have several hashes, you can specify a file with one hash per line. All of the hashes have to be the same type.
-g : If your hash cannot be cracked, search it in Google and show all the results. This option ONLY works with -h (one hash input) option.

The following hash functions are supported by findmyhash:

MD4 - RFC 1320
MD5 - RFC 1321
SHA1 - RFC 3174 (FIPS 180-3)
SHA224 - RFC 3874 (FIPS 180-3)
SHA256 - FIPS 180-3
SHA384 - FIPS 180-3
SHA512 - FIPS 180-3
RMD160 - RFC 2857
GOST - RFC 5831
WHIRLPOOL - ISO/IEC 10118-3:2004
LM - Microsoft Windows hash
NTLM - Microsoft Windows hash
MYSQL - MySQL 3, 4, 5 hash
CISCO7 - Cisco IOS type 7 encrypted passwords
JUNIPER - Juniper Networks $9$ encrypted passwords
LDAP_MD5 - MD5 Base64 encoded
LDAP_SHA1 - SHA1 Base64 encoded

The most basic example, has the following structure:

So for example, if you want to find the text of the MD5 hash 5eb63bbbe01eeed093cb22bb8f5acdc3 (whose original text was 'hello world'), then you would execute the following command on a new terminal:

Lm Hash Example

Whose output will be:

The only disadvantage you have, is the way in you identify the type of hash that you want to crack. MD5 is a 32 character alphanumeric representation and SHA-1 usually comes as a 40 character alphanumeric string (as does SHA-0) MD5 and SHA-1 account for the vast majority of hashes that you can find.

Note

You won't have always luck and your hash may not be listed on the databases of the web services. In this case, you may try to search your hash manually on Google (maybe you aren't so unlucky).

Happy cracking !
