About Me

I’m Jonan, better known online as 4mN3s14. I’m a computer security and forensics student, a CTF player with Dead Pirate Society, and a technical writer who learns by taking systems apart and documenting what happens.

My main interests are offensive security, reverse engineering, digital forensics, OSINT, malware analysis, and Linux internals. In CTFs and security labs, I work across:

• Binary exploitation and return-oriented programming
• Web vulnerabilities and authentication flaws
• Cryptography and implementation mistakes
• Python jails, polyglots, and unusual language behavior
• Malware, rootkits, and Linux kernel security
• Enumeration, privilege escalation, and complete attack chains

I prefer practical work over surface-level summaries. A useful write-up should explain the reasoning, failed assumptions, commands, code, evidence, and remediation well enough for someone else to reproduce the result. Flags and sensitive values are redacted when they do not add educational value.

This blog is my public notebook. It contains CTF solutions, lab walkthroughs, exploit development notes, security research, and lessons learned while building and debugging my own tools and infrastructure. I write to make difficult technical ideas clearer, reinforce what I learn, and leave behind material that is useful beyond a single challenge.

Outside focused security work, I have experience writing across technology and other subjects. That background shapes how I approach technical communication: direct, structured, and grounded in evidence rather than jargon. I also follow gaming and esports, with a particular interest in handheld consoles.
