All of the following are the password cracking attacks performed by the cain tool except for which one?

Brute force attack is a native feature of Cain and Abel, exhaustively trying all possible character combinations to recover a password.

Dictionary attack is a built-in Cain and Abel method that tests passwords against a precompiled wordlist.

DoS attacks are network-layer disruption techniques that overwhelm a target with traffic or requests, which is entirely outside the scope of the Cain and Abel toolset. Cain and Abel is strictly a password auditing and recovery application, and none of its modules are designed to disrupt service availability.

Rainbow attack (rainbow table lookup) is a core Cain and Abel feature used to reverse cryptographic hashes by comparing them against precomputed hash chains.
