A Russian platform on a deliberately slow schedule: the organisers publish one CTF challenge a month and leave it open for the whole month. Categories are web, pwn, crypto and reverse, and the top three solvers each month enter a Hall of Fame.
Pros & cons
Pros
- One task a month leaves room to actually understand it
- Hall of Fame for the top three solvers each month
- Free, and the statements read in Russian
Cons
- The pace is roughly ten tasks a year, which reads slow even when intended
- A challenge closes when the month ends, so there is no backlog to return to
- No archive to grind through: a missed month is a month lost
Who it fits
Fits anyone who needs a deadline more than willpower. One task a month is far easier to finish than two hundred in an archive, and the writeups that come with it are written to be read.
Getting started
- Wait for the monthly drop and take the task on the day it appears
- Work to the flag and to an understanding of why each detail is there
- Send your writeup to the organisers when one exists
History
Runs monthly, with roughly ten challenges planned for 2026 across the main categories, which is why activity counts as slowing rather than active. There is no counter on the site and no archive, so the total is a matter of record rather than something you can check.
