This repository contains my step-by-step solutions, analysis, and writeups for various challenges hosted on the picoCTF platform. It serves as a digital archive of my practical learning journey in offensive security and vulnerability analysis.
- To document analytical approaches and problem-solving methodologies for diverse Capture The Flag (CTF) challenges.
- To maintain a structured reference of concepts, exploits, and scripts developed during the labs.
- To track personal progress in foundational and advanced cybersecurity domains.
The writeups are categorized according to the official picoCTF domains:
- Web Exploitation: Analyzing and exploiting web application vulnerabilities (such as SQL injection and XSS).
- Cryptography: Breaking ciphers, analyzing cryptographic flaws, and understanding encryption mechanisms.
- Reverse Engineering: Analyzing compiled binaries, understanding control flow, and decompiling software.
- Forensics: Investigating file formats, network packet captures (PCAPs), disk images, and hidden data.
- Binary Exploitation: Exploiting memory corruption vulnerabilities, buffer overflows, and format string flaws.
- General Skills: Utilizing essential Linux command-line utilities, scripting, and fundamental security concepts.
The techniques and tools frequently utilized across these challenges include:
- Operating System: Linux / Kali Linux
- Scripting & Automation: Python, Bash
- Analysis & Interception: Burp Suite, Wireshark, Nmap
- Reverse Engineering & Debugging: GDB, Ghidra, CyberChef
These writeups are shared strictly for educational and instructional purposes. To maximize your own learning experience, it is highly recommended to attempt the challenges independently before reviewing the solutions.
