Deep Dive into Pass the hash
Introduction
Aside from the several authentication attacks that are well-known, there is another one called Pass-the-Hash that allows an attacker to gain access to new systems by compromising them. The objective is not just to break the passwords, but also to exploit the password hashes, allowing the attacker to access systems without authorization.
What is “pass the hash”?
An encrypted form of the password is referred to as a “Hash,” and its creation is determined by the hashing method.As of this moment, we have a few different hashing algorithms. The same password will produce the same hash due to the fact that this process is unidirectional.
It is by this method that an adversary is able to obtain the hash of the password and then relay it to the authentication system. As a result, the hash will continue to be the same till the password has not been changed. An extensive number of large companies have been victims of this attack, which results in the loss of substantial amounts of data, financial loss, and, finally, reputational harm.
