Hi, I'm Cajac! 👋 I'm a threat hunter by day and a CTF-player by night. I'm a cybersecurity enthusiast and perpetual learner interested in most things cybersecurity. I'm aspiring to be a purple teamer, practicing both offensive and defensive techniques. I like both theoretical analysis and practical hands-on hacking. I'm based in Sweden. ## About the handle What does 'Cajac' mean? Well, nothing as far as I know. Due to lack of imagination I wrote a small script that generated 5-character [palindromes](https://en.wikipedia.org/wiki/Palindrome) to use as possible a hacker handle. Cajac was the chosen result. ## What else am I up to? ### CTF platforms I spend a fair amount of my free time learning new things and fine-tuning my procedures on several CTF and wargames sites, including for example: * [picoCTF/CyLab Security Academy](https://learn.cylabacademy.org/users/Cajac) * [TryHackMe](https://tryhackme.com/p/Cajac) * [HackTheBox](https://app.hackthebox.com/users/48189) * OffSec's Proving Grounds * Pwn.college * Root Me * We Chall * PortSwigger's Web Security Academy * CryptoHack ### GitHub Most of my CTF-writeups and study notes are collected on GitHub: A few of the repositories are already public and more are likely coming: * [picoCTF-Writeups](https://github.com/Cajac/picoCTF-Writeups) * [TryHackMe-Writeups](https://github.com/Cajac/TryHackMe-Writeups) Feel free to check them out if you like! ### YouTube I collect and create IT security-related playlists on my YouTube-channel to facilitate my learning: [@cajac\_yt](https://www.youtube.com/@cajac_yt). Currently I have more than 400 playlists related to cyber security and programming. Topics such as Threat hunting, Cyber threat intelligence, Capture the flag competitions, Wargames, Penetration-testing, Red teaming, PowerShell, Python, Reverse engineering, Malware, Blue teaming, Digital forensics, Open-source intelligence, DevOps, and Hacking. I don't have, and don't plan to release, any videos created by myself though.
