Brute Forcing

Et tu, Brute?

Dictionary attacks are guesses on usernames or passwords using a dictionary of possible strings or phrases.

Rainbow table attacks is a precomputed table for reversing cryptographic hash functions. It can be used to guess a function up to a certain length consisting of a limited set of characters.

Reverse brute force attack uses a common password or collection of passwords against many possible usernames. Targets a network of users for which the attackers have previously obtained data.

Credential stuffing uses previously-known password-username pairs, trying them against multiple websites. Exploits the fact that many users have the same username and password across different systems.

Attackers may use tools to scan for devices in the area, sniff transmissions OTA and capture transmission streams to crack for authentication payloads within the handshake protocols to obtain passcodes or keys.

In any form of the attacks, the space is lowered when attackers know the data format used, such as base64, etc.
