about this track

cybersecurity hackathons 2026

security events come in two shapes: capture-the-flag contests, where teams solve attack and defence challenges against a scoreboard, and build hackathons, where teams ship a security tool or product.

this page filters the live index for cybersecurity, ctf and capture-the-flag signals in the listing name, host, summary and tags.

faq

what is the difference between a ctf and a cybersecurity hackathon?

a ctf is a timed contest of security puzzles scored by flags found. a cybersecurity hackathon asks teams to build something, such as a detection tool or a hardened app, and judges the result.

do i need security experience to enter?

not always. many campus ctfs include beginner challenges. read the host rules for the difficulty level and team size.

are these events legal hacking?

yes. ctf challenges are built for the contest and scoped by the host. never test systems outside the rules the host publishes.
