This kind of password cracking method uses word lists in combination with numbers and special characters:

A hybrid attack leverages a dictionary of common words and then systematically modifies those words by appending, prepending, or inserting numbers, symbols, or common permutations, thereby increasing the attack's effectiveness against passwords that are dictionary words with minor alterations. This approach is more efficient than a pure brute-force attack for many common password patterns.

"Linear" is not a standard term for a password cracking method.

"Symmetric" refers to a type of encryption where the same key is used for encryption and decryption, not a password cracking method.

Brute Force tries every possible combination of characters within a defined length, without starting from a dictionary of known words or patterns.
