Main types of password attacks
What is a password attack?
Password attacks are any attempt of an attacker to steal or generate passwords so they can gain access to sensitive data and other user accounts.
1. Brute force attack
Brute force attacks refer to any method of generating or guessing passwords and then attempting to use them until attackers eventually gain access. An example of this type of attack is hackers generating possible passwords from public details about a user like their birthday and generating unique passwords based on that data.
2. Dictionary attack
Dictionaries contain commonly used phrases or words that may be included in passwords, which attackers then use as a stepping stone to guess the rest of the password itself.
3. Rainbow table attack
A rainbow table attack is a more complex method of brute forcing passwords, usually by generating hashes. A hash is how your computer stores passwords without simply typing them out in its memory in plaintext — an encrypted version of your password. An attacker would then reverse search the corresponding hash of the target system or network. Once they match a hash in your network, they can then reverse-engineer the plaintext password you use for access.
