Alternative form of cyberattack

(cryptography) An attack on a cryptographic hash function that is able to find a preimage for a hash; that is, it is able to determine (faster than by brute force) some input that results in a known hash when passed through the algorithm.

(cryptography) An attack on a cryptographic hash function that is able to find a second preimage for a hash and its preimage; that is, given a hash and an input that has that specific hash, it is able to find (faster than by brute force) another input with the same hash.

(cryptography) An attack on a cryptosystem that relies only on the attacker's knowledge of some ciphertexts encrypted with that system and key. Less powerful than a known-plaintext attack.

(cryptography) An attack on a cryptosystem that relies on the attacker's knowledge of not just some ciphertexts encrypted with that system and key, but also their corresponding plaintexts (cribs). More powerful than a ciphertext-only attack, but less powerful than a chosen-plaintext attack.

(cryptography) An attack on a cryptosystem that relies on the attacker's ability to choose any plaintext of their liking and encrypt it into the corresponding ciphertext with that system and key. More powerful than a known-plaintext attack but less powerful than a chosen-ciphertext attack.

(cryptography) An attack on a cryptographic hash function that is able to find a hash collision (a pair of different inputs that have the same hash) faster than by brute force.

(cryptography) An attack on a cryptosystem that relies on the attacker's ability to choose any ciphertext of their liking and decrypt it into the corresponding plaintext with that system and key. More powerful than a chosen-plaintext attack.

(military) The detonation of multiple nuclear warheads at the same time, so as to multiply the destructive effect.
