Types of Brute Force Attacks:

Simple brute force attacks: hackers attempt to logically guess your credentials — completely unassisted from software tools or other means.

These can reveal extremely simple passwords and PINs. For example, a password that is set as “guest12345”.

Dictionary attacks: in a standard attack, a hacker chooses a target and runs possible passwords against that username.

These are known as dictionary attacks. Dictionary attacks are the most basic tool in brute force attacks. While not necessarily being brute force attacks in themselves, these are often used as an important component for password cracking.

Some hackers run through unabridged dictionaries and augment words with special characters and numerals or use special dictionaries of words, but this type of sequential attack is cumbersome.

Hybrid brute force attacks: these hackers blend outside means with their logical guesses to attempt a break-in. A hybrid attack usually mixes dictionary and brute force attacks.

These attacks are used to figure out combo passwords that mix common words with random characters.

A brute force attack example of this nature would include passwords such as NewYork1993 or Spike1234.

Reverse brute force attacks: just as the name implies, a reverse brute force attack reverses the

attack strategy by starting with a known password. Then hackers search millions of usernames until they find a match.

Many of these criminals start with leaked passwords that are available online from existing data breaches.

Credential stuffing: if a hacker has a username-password combo that works for one website, they’ll try it in tons of others as well.

Since users have been known to reuse login info across many websites, they are the exclusive targets of an attack like this.
