Which attack tries all possible upper and lower case combinations of a word in the input dictionary?

• A. Toggle-Case Attack
• B. PRINCE Attack
• C. Rubeus
• D. Golden Tickets

Answer: (A)

Toggling the case of each character in dictionary words to cover all capitalization possibilities is the idea here. A toggle-case attack generates every possible upper/lower case combination for each word in the input dictionary. For a word of length n, that means 2^n variations, including all-lowercase, all-uppercase, and every mixed-case form in between. This makes it effective against passwords that are simple dictionary words but with mixed-case usage, since many users mix case even when choosing from common words. In practice, you’d take a word like “password” and try variations such as Password, PaSSword, PASSWORD, and so on, until you hit the correct one. The other options relate to different domains: one is a cryptanalysis or cipher-related technique, another is a Kerberos toolkit, and the last is a Kerberos credential-forging attack. They don’t describe the technique of enumerating all case combinations in a dictionary.
