WebNov 18, 2024 · Adversary 1 – Hash Collision Attacks. In our first adversarial setting, we investigate the creation of hash collisions. We perturb images so that their hashes match predefined target hashes. The first step to perform the attack is to create a surrogate hash database from a data folder. WebSHA-1 collision attacks. A hash function H is a many-to-one function, and thus the existence of collisions, i.e., pairs of distinct inputs M and M’ with identical outputs H(M)= H(M’), is unavoidable. In a cryptographic hash function, collisions should in theory be not significantly faster to find than in a brute force attack.

In computer security, pass the hash is a hacking technique that allows an attacker to authenticate to a remote server or service by using the underlying NTLM or LanMan hash of a user's password, instead of requiring the associated plaintext password as is normally the case. It replaces the need for stealing the plaintext password to gain access with stealing the hash.
