Cybersecurity CTF & Lab Writeups
Step-by-step cybersecurity writeups from TryHackMe, Hack The Box, BTLO, PortSwigger and other security labs. Learn practical penetration testing, web security, Linux, digital forensics, enumeration, vulnerability analysis and security investigation through hands-on challenges.
Practical Cybersecurity Writeups for Hands-On Learning
Cybersecurity is best learned by solving real problems. Our cybersecurity writeups document practical challenges from Capture The Flag competitions, penetration testing labs, security training platforms and vulnerability research environments.
Each walkthrough is designed to explain the methodology behind a solution rather than simply provide an answer. Explore reconnaissance, enumeration, vulnerability discovery, exploitation, privilege escalation, digital forensics, authentication attacks, web application security and post-exploitation techniques through practical examples.
These CTF writeups are useful for cybersecurity students, penetration testers, SOC analysts, security researchers and anyone building practical information security skills.
What You Can Learn From Our CTF Writeups
Our security lab walkthroughs cover a wide range of cybersecurity concepts and offensive security techniques. Depending on the challenge, you may encounter topics such as:
- Network reconnaissance and service enumeration
- Linux and Windows security investigation
- Web application vulnerabilities and exploitation
- Authentication and access-control weaknesses
- Privilege escalation techniques
- Digital forensics and file analysis
- Steganography and hidden-data analysis
- Password attacks and credential security
- Vulnerability identification and analysis
- Incident investigation and security reasoning
