Capture The Flag

A Capture The Flag is a cybersecurity exercise/competition, in which the goal is to find hidden flags (such as monsec{welcome_0x1337}) inside purposefully-vulnerable programs and websites, that are usually created by the event’s organisers. It is highly regarded as an ethical and safe way to learn and demonstrate cybersecurity skills.

MonSec Beginner CTF

The MonSec Beginner CTF is our very own annual CTF designed and engineered towards beginners. It is usually held early in the year and runs for approximately 6 hours.

For updates on this event keep an eye out at our Discord server and social media.
