I hope this time that I&rsquo;ll be regular.</p> <p>Last weekend I played the <a href="https://hackpack.club/ctf2022/">HackPack2022</a> CTF. It was a really fun CTF and I learned a lot of things.</p> <p>Out of all the challenges solved, I am posting the writeups of the most interesting ones. Enjoy !</p> <p><img src="https://ev1lm0rty.com/images/hackpack2022/Pasted%20image%2020220411204154.png" alt=""></p> <h2 id="web--imported-kimichi">Web: Imported Kimichi</h2> <p>This challenge highlighted &ldquo;insecure unpickling&rdquo; bug .
