As you might expect, the more computing horsepower you have, the more successful you will be with this approach.

Now, I thought it might be worthwhile to begin a series on password cracking in general.

Password cracking is both an art and a science, and I hope to show you the many ways and subtleties involved.

We will start with the basic principles of password cracking that are essential to ALL password cracking techniques, followed by some of the tools and technologies used.

Then, one by one, I will show you how to use those principles and technologies effectively to crack or capture the various types of passwords out there.

A username and password are used on computer systems, bank accounts, ATMs, and more.

The ability to crack passwords is an essential skill to both the hacker and the forensic investigator, the latter needing to hack passwords for accessing the suspects system, hard drive, email account, etc.

In those cases, the hacker or forensic investigator can either employ greater computing resources (a botnet, supercomputer, GPU, ASIC, etc.), or they can look to obtain the password in other ways.

In addition, sometimes you dont need a password to access password-protected resources.

For instance, if you can replay a cookie, session ID, a Kerberos ticket, an authenticated session, or other resource that authenticates the user after the password authentication process, you can access the password protected resource without ever knowing the password.

Sometimes these attacks can be much easier than cracking a complex and long password.

I will do a tutorial on various replay attacks in the near future (look out specifically for my upcoming article on stealing the Facebook cookie to access someones Facebook account).

Hashes are one-way encryption that are unique for a given input.

These systems very often use MD5 or SHA1 to hash the passwords.

In the Windows operating system, passwords on the local system are stored in the SAM file, while Linux stores them in the etcshadow file.

These files are accessible only by someone with rootsysadmin privileges.

In both cases, you can use a service or file that has rootsysadmin privileges to grab the password file (e.g.

To put it simply, it just runs through a dictionary of words trying each one of them to see if they work.

Although such an approach would seem impractical to do manually, computers can do this very fast and run through millions of words in a few hours.

This should usually be your first approach to attacking any password, and in some cases, it can prove successful in mere minutes.

This means that even if you can get to the area or file that stores the password, what you get is an encrypted password.

One approach to cracking this encryption is to take dictionary file and hash each word and compare it to the hashed password.

A faster approach is to take a table with all the words in the dictionary already hashed and compare the hash from the password file to your list of hashes.

Brute force password cracking attempts all possibilities of all the letters, number, special characters that might be combined for a password and attempts them.
