For over two decades, HACKTIVITY has been the beating heart of the Central and Eastern European hacker scene: one intense day of deep technical talks, hands-on workshops and a buzzing community EXPO. This October we bring it back, and the 2026 line-up is our sharpest yet.
Two dozen confirmed sessions. Speakers from a dozen countries. And a clear signal of where security is heading: AI under attack and AI as the attacker, autonomous agents slipping their leash, cloud secrets surfacing where they shouldn’t, cars turned inside out, and the offensive tooling that ties it all together.
This is the first wave. More talks and workshops are landing soon.
