[{"content":"I\u0026rsquo;ve tried keeping notes in a lot of places. Obsidian, a Notion workspace I forgot the password to, a notes/ folder that lives on three different laptops. None of it survived more than a few months.\nSo this is attempt number four, except this time it\u0026rsquo;s public, which hopefully makes me a bit more careful about what I write.\nWhat goes here Mostly CTF writeups. I play rev, forensics and misc for the most part. I\u0026rsquo;ll post solutions after each competition ends, usually for the challenges I found interesting or got stuck on for an embarrassingly long time.\nSome notes from writing challenges for RoCSC this year too. Being on the author side changes how you look at a binary.\nAnd the occasional networking thing. I did the CCNA track in 2025 and there\u0026rsquo;s a lot of material I don\u0026rsquo;t want to re-learn from scratch.\nWhat doesn\u0026rsquo;t No tutorials on \u0026ldquo;how to get into cybersecurity\u0026rdquo;. There are enough of those. No tool roundups either.\nIf you spot a mistake in a writeup, email me. I\u0026rsquo;d rather fix it than have someone copy a wrong exploit.\n","permalink":"https://victortrend.space/posts/2026-11-01-hello/","summary":"Why this exists and what I plan to put here.","title":"Starting a blog, again"},{"content":"I\u0026rsquo;m Victor, a high school student from Targoviste, Romania. I study maths and computer science at Colegiul National Constantin Carabella.\nMost of my free time goes into CTFs. I lead SelfwashRO and I\u0026rsquo;ve also played with vianu_hack. I mostly take the reverse engineering, forensics and misc challenges. Give me a stripped binary or a memory dump and I\u0026rsquo;m happy for a few hours.\nIn 2026 I switched sides for a bit and wrote challenges for the Romania Cyber Security Challenge bootcamp and finals. Writing a challenge teaches you more about a bug class than solving ten of them.\nOn the networking side I finished all three CCNA modules in 2025.\nContact Email: trandafir.victor2008@gmail.com ","permalink":"https://victortrend.space/about/","summary":"Who I am and what this site is for.","title":"About"},{"content":"Last updated November 2026.
