| Top 10 Password Crackers: Download Free Password Hacking Tools Posted: 08 Apr 2011 09:34 AM PDT 1. Cain and Abel : The top password recovery tool for Windows UNIX users often smugly assert that the best free security tools support their platform first, and Windows ports are often an afterthought. They are usually right, but Cain & Abel is a glaring exception. This Windows-only password recovery tool handles an enormous variety of tasks. It can recover passwords by sniffing the network, cracking encrypted passwords using Dictionary, Brute-Force and Cryptanalysis attacks, recording VoIP...

| Posted: 08 Apr 2011 09:35 AM PDT This article has been posted by our fellow members Mr.Amey Anekar, Mr.Rahul and Mr Sachin. Before going ahead with the discussion let us first explain to you why it is so difficult to crack windows passwords. Windows uses NTLM, LM or MD5 algorithm to encrypt the plain text passwords and saves it in system32/config folder. The encrypted passes that are saved in the SAM file under system32/config are called hashes. Now dont just browse the SAM file and attempt opening it. It's useless doing this...

| How to hack Administrator Password: Administrator Password Guessing Posted: 08 Apr 2011 09:32 AM PDT Administrator Password Guessing Assuming that NetBIOS TCP139 port is open, the most effective method of breaking into NT/2000 is password guessing. Attempting to connect to an enumerated share (IPC$, or C$) and trying username/password. Default Admin$, C$, %Systemdrive% shares are good starting point.One common security lapse seen is to leave in the built-in Administrator account with a null password. Password guessing appeals to the attacker because complicated passwords are difficult... Do you want to read more..Visit my site @ http://www.amarjit.info |
| Hacking Tool: John the Ripper: Crack Password Posted: 08 Apr 2011 09:33 AM PDT Hacking Tool: John the Ripper It is a command line tool designed to crack both Unix and NT passwords. John is extremely fast and free The resulting passwords are case insensitive and may not represent the real mixed-case password.John the Ripper is a fast password cracker, currently available for many flavors of UNIX (11 are officially supported), DOS, Win32, BeOS, and OpenVMS. Its primary purpose is to detect weak UNIX passwords. John the Ripper is a part of Owl, Debian GNU/Linux,... Do you want to read more..Visit my site @ http://www.amarjit.info |
| Automatic Password Cracking Algorithm Posted: 08 Apr 2011 09:33 AM PDT Automatic Password Cracking Algorithm Find a valid user Find encryption algorithm used Obtain encrypted passwords Create list of possible passwords Encrypt each word See if there is a match for each user ID Repeat steps 1 through 6However, the vulnerability does not arise from the hashing process but from the storage. Most systems do not "decrypt" the stored password during authentication, but store the one-way hash. During the login process, the password entered is run through the...

| Manual Password Cracking Algorithm Posted: 08 Apr 2011 09:33 AM PDT Manual Password Cracking Algorithm Find a valid user Create a list of possible passwords Rank the passwords from high probability to low Key in each password If the system allows you in - Success Else try till success In its simplest form, password cracking can be automated using a simple FOR loop. In the example below, an attacker creates a simple text file with usernames and passwords that are iterated using the FOR loop. A text file is created to serve as a dictionary from which...

| Password Sniffing: How to sniff passwords from LAN Posted: 08 Apr 2011 09:33 AM PDT Password Sniffing Password guessing is hard work. Why not just sniff credentials off the wire as users log in to a server and then replay them to gain access?Most networks use the broadcast technology; which means that every message emanating from any computer on the network can be captured by every other computer on the network. Normally, the message is not taken by other computers as the intended recipient's mac address does not match their mac address. Therefore, all the computers...
