The scoring server will be open when the game starts.
All challenges will be on the score server. Submit the flag in each challenge’s text box. You’ll receive points if it's correct.
You can solve challenges in any order. Some challenges may be related to other challenges, in which case you need to solve the others first.
Some challenges may require searching through someone’s social networking accounts. Do not contact the account owner, anyone you think is related to the account, or any related organization for hints or answers. Use only the information that is already available to the public.
Challenges that can only be solved onsite (SIGINT and HUMINT) will have double scores to the challenges with comparable difficulty.
There are no challenges that require you to use paid services.
When sharing a write-up (especially for SIGINT), please be careful to delete/modify any personally identifiable information, communication data that does not concern the challenge, etc.
As mentioned in “Prohibited Activities,” an act of violence and illegal activity is strictly prohibited.
The player that earned the most points will be the winner. The top 3 winners will be announced after the game and awarded at the AVTokyo venue (tickets are required to enter the venue).
If you have any questions, post them on AVTokyo Discord channel #xint-ctf-general or send a DM to X (Twitter) @pinja_xyz.
