SECCON 14 Open Conference

SECCON is the largest CTF competition in Japan. We hold an in-person event called "Dennoh Kaigi" (電脳会議) alongside with SECCON CTF Final competition every year. Many workshops, presentations, and mini CTFs are gathered in Dennoh Kaigi. "Open Conference" is a presentations track of Dennoh Kaigi.

At last year's SECCON Open Conference 13, various presentations were made, including on attack methods against browser extensions, the development of attack detection technology for connected cars using machine learning, and experiences taking on OSINT CTF.

We are inviting proposals for presentations via a Call for Presentations. We're looking for presentations about technological research or tool around Cyber Security. We are also looking for any difficulty proposals and it is not needed that you have previous speaker experience. :)
