How Cyber Criminals Predict New Passwords from Old Ones

One common technique cyber criminals use to predict new passwords from old ones is by leveraging patterns and common trends seen in the way people create and update their passwords. By understanding these patterns, hackers can make educated guesses that often prove successful.

One method hackers use is dictionary attacks, where they use automated tools to test commonly-used passwords or words found in dictionaries against a target's password. If a hacker knows a person's old password, they can try variations or combinations of that password to guess the new one.

Another technique is brute force attacks, where cyber criminals systematically try every possible password combination until they find the correct one. Knowing a person's old password can give hackers clues to refine their brute force attack and expedite the process.
