Description

Welcome to watevrCTF 2019! watevrCTF is a security capture the flag competition for everyone, whether you are just starting out or have already played a fair amount of CTF competitions before. Our aim is to provide quality challenges that do not require unreasonable guessing to solve.

A CTF competition is a cybersecurity competition where you get to solve lots of computer-related puzzles and challenges. Each challenge contains a string called a flag, which you must find and submit to this website to receive points.

The event takes place online during a 48h period between December 13th 19:00 UTC and December 15th 19:00 UTC.

The flag format is watevr{example_flag} unless specified otherwise.

This CTF has dynamic scoring. The score function is round(10 + 490 / (1 + (solves - 1) / 12)) for all challenges.
