Part 5/8:

With technology evolving rapidly, Dave showcases the capabilities of a modern AMD Threadripper CPU equipped with dual Nvidia GPUs, which can execute 200 billion hashes per second. Using a software tool called John the Ripper, he embarks on password cracking exercises that highlight the ease with which weak passwords can be compromised.

Offline vs. Online Attacks

Dave explains the distinction between online and offline attacks. Online attacks involve brute-forcing login attempts on live systems, while offline attacks use a copy of hashed passwords to attempt to decode them without alerting the system. The practicalities of gathering hashes, particularly from Unix systems, are discussed, providing insight into how attackers might acquire sensitive information.
