Cyber Security Complete Course 2026 | From Zero to Job Ready Ethical Hacker + Blue Team Expert | The Techzeen - Cyber Security Tutorial #23: Hashcat | Crack Passwords FAST (GPU Power) | Kali Linux 2025

Want to see how Hashcat cracks hashes at GPU speed? 🚀 In this tutorial I explain why Hashcat is the go-to high-performance cracking tool, how it compares to John the Ripper, and demonstrate dictionary, mask & rule attacks on a safe test hash. Beginner friendly — focused on learning and defensive awareness. What you’ll learn (theory + practical): ✅ What is Hashcat and why it’s so powerful (GPU acceleration, multi-hash support) ✅ When to use Hashcat vs John the Ripper (GPU vs CPU; scale vs flexibility) ✅ How Hashcat detects devices (hashcat -I) and why GPUs matter ✅ Practical attacks: dictionary (-a 0), mask (-a 3) & rules (-r) ✅ How to read cracked results (--show) and potfile behavior Practical demo overview: * Install & verify Hashcat on Kali (sudo apt install -y hashcat) * Prepare small demo wordlist & hash (rockyou subset; raw-MD5 example) * Run dictionary: hashcat -m 0 -a 0 hashes.txt wordlist.txt * Run mask: hashcat -m 0 -a 3 hashes.txt '?l?l?l?l?d?d' * Apply rules: hashcat -m 0 -a 0 hashes.txt wordlist.txt -r best64.rule ⚠️ Legal Disclaimer Educational Use Only: All demonstrations were performed on systems I own or authorized lab platforms (TryHackMe / Hack The Box / local VMs). Do not run Hashcat or any cracking tools against systems you do not own or lack explicit written permission to test. Illegal misuse is your responsibility. I am not liable for misuse of this content. ⭐ Don’t just watch — Level up and defend like a pro. 📢 Subscribe to The Techzeen & become a Cyber Security & Ethical Hacking Expert in 2025 🔔 Hashcat Offline-Password-Cracking (Repo - Educational Pupose Only): https://github.com/farzeen-ali/Hashcat-Offline-Password-Cracking-Educational-Purpose-Only Cyber Security Concepts: https://github.com/farzeen-ali/Cyber-Security-Concepts Cyber Security Full Course 2025: https://www.youtube.com/playlist?list=PL5OhSdfH4uDuCcQ-NZ4lYa3S07FQTFtrY DevOps Tutorial 2025: https://www.youtube.com/playlist?list=PL5OhSdfH4uDsyUM02ZHl2mOYBpihCYsml React Native Full Course 2024 : https://www.youtube.com/playlist?list=PL5OhSdfH4uDuUpj3fwknoUVBkT2oMXyOl #Hashcat #CrackPasswords #PasswordCracking #CyberSecurityTutorial #KaliLinux #GPUCracking #HashCracking #OfflineCracking #JohnTheRipper #InfoSec #TheTechzeen #PenTesting #CyberSecurity2025 #CyberSecurityFullCourse #EthicalHackingFullCourse
