Event organizers
IERAE CTF is the CTF organized by ierae, the CTF team of GMO Cybersecurity by Ierae, Inc.
GMO Cybersecurity by Ierae, Inc. is a Japanese security company with many CTF players. We have been helped by and grown with those CTF players, and now we want to help energize the community.
[Update]
We will provide seven challenges in the "Homework" category, just for fun.
These challenges are already public as they were provided in the IERAE DAYS 2023 event last year.
Each challenge is only 1pt, so it will not affect to the contest result too much.
Check out the details at https://github.com/gmo-ierae/ierae-days-ctf-2023 !
Also, we got sponsored by OffSec!
