The SANS Holiday Hack Challenge is an innovative and free annual virtual convention that invites participants to walk around a virtual convention center, watch talks on #infosec topics, and participate in excellent hands-on hacking challenges at a range of difficulties for all participants. A whimsical plot ties everything together, resulting in a unique and engaging experience. Participants are invited to submit a writeup at the end of the conference, with prizes available for some of the best/most technical writeups.
