In an offline attack, the database of user credentials (the SAM file in Windows, or the /etc/shadow file in Linux, for example) is usually stolen and attacked offline, outside of the normal online operating conditions of the system.Īttackers are usually after the password hashes contained in the database, which are forms of the passwords subjected to cryptographic hashing algorithms. In an online attack, the attacker attempts to log in as a user by guessing the user’s password.
There are several different types of password attacks that we will discuss, including brute-force, dictionary attacks, rainbow tables, and hybrid attacks.
Logs into the system as a valid user and from there attempts to escalate her privileges or access systems and data. Password attacks are very common and are used to attempt to gain access to a system by discovering the username and password combination for a valid user on the host.
