Final answer:

Cybercriminals use brute force and dictionary attacks to obtain passwords and usernames, emphasizing the importance of password complexity.


Explanation:

Brute force attack is the trial-and-error method cybercriminals use to obtain passwords and usernames by trying all possible combinations of letters, numbers, and symbols. This method works for relatively short passwords.

Another method used is dictionary attacks, where cybercriminals try dictionary words, common variations of them, and previously cracked passwords to guess the correct combination.

Password complexity, including using a combination of upper and lower case letters, special characters, and numbers, is crucial in preventing such attacks.
