LEARN HYDRA: Master Password Cracking via Brute Force Across Multiple Services (SSH, FTP, HTTP, RDP)
About this ebook
This book is ideal for students and professionals in offensive security, infrastructure analysts, and those seeking to master Hydra through practical brute-force testing. You will learn to configure attacks against various protocols, explore authentications protected by tokens, captchas, and multiple layers, and integrate Hydra with widely used tools in penetration testing.
Includes:
• Attacks against FTP, SSH, HTTP, Telnet, SMB, RDP, and VNC
• Use of custom lists, dictionary parameters, and distributed brute-force
• Automation with bash scripts, logs, and multiple simultaneous targets
• Integration with Nmap, Burp Suite, ZAP, Metasploit, and DevSecOps pipelines
• Authentication cracking on REST APIs, forms, and dynamic pages
• Detection of failures in multi-factor authentications and protection mechanisms
• Techniques for bypassing captchas, delays, blocks, and IP-based protections
• Analysis of HTTP responses, session tokens, and custom headers
Master Hydra to strengthen audits, penetration tests, and security projects with technical precision and strategic automation.
