Editing Access Control attacks

'''Access control attacks''' generally skip access control methods to '''steal data''' from systems like communication links, networks, computers, services and sensitive data. Adversaries securely break access control by logging in as an authorized user and accessing their credentials.


==Password Attack==

A password attack is any means by which a hacker attempts to obtain a user’s login information. In many cases, passwords can simply be guessed after trying a few common words, such as “password” or "root".

===Brute Force===

The Brute force attack is guessing a key by testing all possibles combinations of numbers and letters through a computer program until find the one that allows access.

*'''Hybrid brute force attacks''':It uses a systematic approach to guess that it does not use external logic.
*'''Reverse brute force attack''':Involves using a common password or group of passwords against multiple possible usernames.
*'''Credential stuffing''':Credential stuffing is a unique form of brute force attack that uses breached username and password pairs.


Automated tools are also available to help with brute-force attacks, the most popular are:

*Aircrack-ng

*John the Ripper

*Rainbow Crack

*Crack

*Hashcat

*DaveGrohl

*Ncrack

*THC Hydra


===Rainbow Table===

The passwords in a computer system are not stored directly as plain texts, but are hashed using encryption. A hash function is a one way function, which means that it can’t be decrypted. Whenever a user enters a password, it is converted into a hash value and is compared with the already stored hash value. If the values match, the user is authenticated.

'''A rainbow table is a database that is used to gain authentication by cracking the password hash.''' It is a pre-computed dictionary of plain-text passwords and their corresponding hash values that can be used to find out what plain-text password produces a particular hash.

-Nearly all distributions and variations of Unix, Linux, and BSD use hashes with [[salt]]s, although many applications use just a hash with no salt (typically [[MD5]]).
-The Microsoft [[Windows NT]]/2000 family uses the LAN Manager and NT LAN Manager unsalted hashing method, based on [[MD4]], which makes it one of the most popularly generated rainbow tables.<ref>https://en.wikipedia.org/wiki/Rainbow_table#Common_uses</ref>
