UTM_erickhoo – July 5, 2018, 3:21 a.m.

cannot register because the box to fill country shows no results found and I cannot input country name


UTM_erickhoo – July 5, 2018, 3:45 a.m.

it looks like my service provider blocks this url http://data.ctf.360.cn:1234/adminapi/all_location. I just bypass it and problem solved.

This is ridiculous. We should play during the night? First bloods are only for chinese teams?

"Open time: UTC 02:00-10:00, July 6th; UTC 01:40-10:00, July 7th."

Uhh... what? Why would you do that even if you wanted to "keep pace with on-site CTF"?
It's a jeopardy, on-site teams can go to sleep safely even if the system stays open. ???


peter_ – July 5, 2018, 8:06 p.m.

And what is the deal with the first-blood bonus points?
I can't really think of them as anything else than an obvious advantage given to the on-site and chinese teams, since the rest of the world would be sleeping at that time. There are really no excuses.

what's the point of a registration deadline?


serafinapekkala444 – July 6, 2018, 8:53 a.m.

oké, and what to do with my flag found?


Pharisaeus – July 6, 2018, 9 a.m.

For all complaining people, honest advice: don't bother :)

1. Usually remote access to chinese competitions is rather poor for international teams, so any online-tasks are pointless.
2. Tasks are prepared by the participating teams, and if opponents solve your challenge, then they gain points over you. Theoretically there are some points awarded by judges and other teams for the quality of tasks, but from experience we know that judges avoid awarding points which would change the ranking. As a result the "winning strategy" is to make borderline-unsolvable challenges. Even is something is solvable, those are all ~500p challenges anyway. The kind that get 0-5 solves on a CTF. Last year vast majority of challenges weren't solved by any of the teams.
