About

Cybersecurity, hacking, certifications, mentoring, programming, red teaming, etc. All these things require you to be constantly learning, but how does one do that effectively? This channel is dedicated to an 'organic' learning style where I will be experimenting with and learning interesting things related to cybersecurity. My hope is that by sharing my curiosity, thoughts, opinions, successes, and failures, we will all grow in our understanding and passion for all things cybersecurity.

Video Description

Welcome to the ultimate beginner-friendly penetration testing tutorial! In this full boot-to-root CTF walkthrough, we break down every step needed to compromise the vulnerable machine, DC-1 from VulnHub. This video is perfect for anyone just starting their ethical hacking journey, studying for the CompTIA PenTest+ certification, or looking for a practical, step-by-step introduction to the pentesting methodology. Here’s what you’ll learn in this DC-1 VulnHub Writeup: - Information Gathering: Using Nmap to find open ports and services. - Vulnerability Exploitation: Identifying and exploiting a critical vulnerability (Drupal). - Reverse Shells: Gaining initial access to the system. - Privilege Escalation: How to find a local vulnerability and gain root access to complete the challenge. Mastering these core skills is essential for passing the PenTest+ exam and becoming a professional ethical hacker. 🚀 Ready to Get Certified? This DC-1 walkthrough gives you a sample of the hands-on demos I cover in my full course "The Complete PenTest+" video study course! No "Death-by-PowerPoint" here! Get engaging, comprehensive theory, demonstrations, and real-world examples to master the PT0-002/PT0-003 syllabus (we have a lot of FUN!!!) 🔗 Enroll in the The Complete PenTest+ Course at the Simply Cyber Academy: https://academy.simplycyber.io/l/pdp/the-complete-pentest-course-pt0-003 Discord Server: https://discord.gg/5wXnuQVx CTF Resources: ========================================================= DC-1 VulnHub Download: https://web.archive.org/web/20250912134756/https://download.vulnhub.com/dc/DC-1.zip Kali Linux: https://www.kali.org/get-kali/#kali-platforms Chapters ======================================================= 00:00 What We'll Learn 01:16 Host Discovery 01:58 Service Enumeration 06:22 Web App Vulnerability Assessment 08:55 Web App Exploitation w/Metasploit 13:09 Brute-Force for Privilege Escalation 15:30 More Privilege Escalation 19:04 Abuse SUID for ROOT Access 21:30 Lessons Learned #CompTIA #PenTestPlus #PenTest+ #CTF #VulnHub #DC1 #BootToRoot #PenetrationTesting #EthicalHacking #CybersecurityCareer #BeginnerHacking #Nmap #PrivilegeEscalation #KaliLinux #InfoSec #ceh #certifiedethicalhacker #metasploit #webappsecurity #owasp
