Getting Started with Hashcat (Stream Session)

Security practitioner PNI leads a hands-on instructional workshop in the Password Village, demonstrating how to install, configure, and operate Hashcat on an NVIDIA GPU workstation to perform high-speed password cracking [00:00]. PNI guides viewers through downloading Hashcat, importing and verifying developer GPG signing keys, configuring the NVIDIA CUDA toolkit, and updating system path configurations (`ld.so.conf.d`) to ensure optimal GPU acceleration [03:28, 08:32].

The presentation covers the fundamental syntax and attack modes of Hashcat. PNI demonstrates running straight dictionary attacks (`-a 0`) using classic wordlists like RockYou against Windows NT hashes (`-m 1000`) captured from penetration tests and Responder LLMNR/NBT-NS poisoning attacks [12:49]. He explains how to interpret Hashcat's console status display, including candidate speed metrics, GPU temperature monitoring, device utilization, restore checkpointing, and cracked hash recovery rates [16:12].

PNI illustrates how GPU acceleration drastically reduces cracking time, demonstrating Hashcat evaluating candidates at over 5.8 billion hashes per second and rapidly cracking nearly 45% of the target sample set in seconds [19:44]. The session concludes with practical tips on rule-based attacks, mask-based brute forcing, and foundational concepts for attendees following along with advanced Password Village sessions [23:41].
