Bunkai Mini CTF at Cyber Day 2026 in Ljubljana

 
On 15 October 2026, we are at Cyber Day 2026 in Ljubljana, and we are bringing something to try with your own hands: a mini capture-the-flag (CTF) at the Bunkai booth in the Cybervillage.

 

Why a CTF

Cyber Day is about cyber resilience for micro, small and medium-sized enterprises. For any company that makes a connected product, the EU Cyber Resilience Act (CRA) turns that into a concrete task: show evidence that the product is secure, or face fines up to EUR 15 million or 2.5% of global annual turnover.
Most product teams we meet have no security specialist on staff. Their question is practical: “How do we test this ourselves?” A talk can describe the answer. A CTF lets you do it.

 

What You Do at the Booth

We have set up demo IoT devices and planted weaknesses in them on purpose. Next to each one sits a securely configured counterpart.

 

– Run an automated security test on a demo device with Bunkai
– Read the report and find the planted weaknesses
– Answer the challenge questions and collect points on the live scoreboard

 

Come for one challenge or stay for the whole set.

 

Who It Is For

You do not need a security background. Every challenge tells you where in Bunkai to look, so product managers, compliance officers, developers and quality engineers can all take part.

 

What You Take Away

– A first-hand view of an automated IoT security test, from start to report
– The difference between the report of a weak device and a secure one
– An idea of how findings map to standards such as the CRA and ETSI EN 303 645
