It is hosted at and is a part of Norway&amp;rsquo;s largest LAN party: &lt;a href="https://www.tg.no/"&gt;The Gathering&lt;/a&gt;. The competition runs over four days, and the goal is to leverage your knowledge of computers, networking, programming, operating systems, compilers, authentication, cryptography, steganography, safe-cracking(!), and more to coerce secrets from combinations of data, programs, and hardware.&lt;/p&gt;
&lt;p&gt;After a nail-biting last leg with strong finishes by several teams, featuring both jury interventions and pwned competition infrastructure, I was positively excited to be awarded the 3rd prize of NOK 2000.&lt;/p&gt;</description></item></channel></rss>
