The talks and hosts were amazing ! Special shoutout to <a href="https://tuxlu.fr/">Tuxlu</a>, with whom I had the pleasure to discuss during the event.</p> <p>On Saturday evening, a public wargame was hosted with PWN, Reverse, Web, Game Hacking and Cryptography challenges. Though I typically enjoy solving Forensics challenges, I here had to adapt and change categories.</p> https://blackwall.re/posts/htb-apocalypse-2025/ Wed, 26 Mar 2025 14:59:42 +0100 https://blackwall.re/posts/htb-apocalypse-2025/ <p><img src="https://blackwall.re/posts/htb-apocalypse-2025/pictures/banner.jpg" alt="banner"></p> <p>This page contains my writeups for the challenges I solved for my team <a href="https://ctf.hackthebox.com/team/overview/224440">Hackpocalypse</a>. While I mainly focused on Forensics, I also solved some challenges from other categories.</p> <p>Overall, this was a very entertaining and high-quality event by HTB and I particularly loved the Fantasy / MMOesque vibe of it!</p> <p>Enjoy!</p> <hr> <h2 id="forensics-">Forensics 🫆</h2> <h3 id="a-new-hire">A new Hire</h3> <p><em>Difficulty: Very easy</em></p> <p><strong>Question</strong>: The Royal Archives of Eldoria have recovered a mysterious document—an old resume once belonging to Lord Malakar before his fall from grace. At first glance, it appears to be an ordinary record of his achievements as a noble knight, but hidden within the text are secrets that reveal his descent into darkness.</p> https://blackwall.re/about/ Mon, 01 Jan 0001 00:00:00 +0000 https://blackwall.re/about/ <style> .meta { display: none; } </style> <p><strong>Welcome to my little corner of the Internet !</strong></p> <h2 id="whoami-">whoami 🧑‍💻</h2> <p>I’m a french cybersecurity student who believes in FOSS and GNU/Linux (I use arch btw...).</p> <p>I’m also interested in mechanical keyboards and a die-hard Star Wars fan.</p> <h2 id="whatis-">whatis 🌐</h2> <p>Here you’ll find posts about my ongoing / finished projects around GNU/Linux, Cybersecurity, Selfhosting and, of course, mechanical keyboards !</p> <p>You can message me on Mastodon <a href="https://infosec.space/@plastic">@plastic@infosec.space</a> and add my RSS feed to your reader to receive any new posts automatically.</p> https://blackwall.re/search/ Mon, 01 Jan 0001 00:00:00 +0000 https://blackwall.re/search/
