What Is Offline Password Cracking?

Offline Password Cracking definition and explanation.

Offline password cracking technique involves recovering passwords from an already obtained password hash file. This happens after a hacker has already gained local access to an infected endpoint and starts to collect locally stored hashes or conducts other methods to attack the network, such as LLNMNR poisoning. The password/hash file is then dumped by the hacker on his local machine to initiate the process of password cracking via rainbow tables or other brute force methods.

By responding to LLMNR/NBT-NS network traffic, adversaries may spoof an authoritative source for name resolution to force communication with an adversary controlled system. This activity may be used to collect or relay authentication materials.
