Please update your profile Apr 11, 17:41 UTC

Hello competitors,

This is quick reminder to please check and make sure your profile is up to date. We have added an “Interested in employment” option in order to reduce noise to competitors who are not interested in recruitment emails. If you are interested in recruitment emails from MITRE please take a moment to make sure this box is checked on your profile. The option to do so can be found by clicking on your name in the top right corner of the scoreboard and choosing “Edit your account”.

Thank you,

MITRE CTF Team
