TSG is the official computer society of The University of Tokyo, and also the name of the CTF team organized by its members.
After two years of silence, we are back again. We also incorporate new technologies that have emerged over the past two years to ensure that our CTFs are of even higher quality!
As a bonus, the greatest teams will be awarded a prize with $$$ thanks to Flatt Security Inc. Don’t miss it!
* The prize will be paid with PayPal. If it doesn't suit you, we can pay that in BitCoin at an arbitrary exchange rate we determine.
* The teams must publish the writeups of the solved problems to get their prizes.
Don’t prevent other teams from having fun.
Don’t share flags or hints, or you’ll be banned.
Don’t attack (e.g. DoS) our infrastructure, or you’ll be banned.
Don’t do automated scanning. It will be considered to be DoS.
The flag format is TSGCTF{blahblah}, unless otherwise specified.
