Insights from 'CYBER ADVENTURE 2026'

On July 5, 2026, Shihiki Shibata, the CEO of Kort Valuta, participated in a significant event called 'CYBER ADVENTURE 2026,' organized by the Junior Chamber International Japan. This session focused on the theme 'Why Cyber Attacks Never End', emphasizing the pressing need for effective cybersecurity strategies in the age of AI.

The Presentation Overview

During his talk, Shibata addressed a common misconception that merely promoting awareness and caution is sufficient to combat cyber threats. He elaborated on the structural reasons behind the persistence of cyber attacks, tracing the evolution of these issues from the early days of computing through various technological advancements up to the present AI-driven landscape.

Shibata discussed three primary perspectives in understanding these threats:
1. The differentiation between commands and data;
2. The critical aspect of designating permissions;
3. Exploring the historical contexts that have shaped current cybersecurity protocols.

He provided insights into how familiar threats such as phishing and account takeovers stem from psychological vulnerabilities and habitual behaviors.

Furthermore, he pointed out the alarming rise in newly reported vulnerabilities associated with the Linux kernel, most of which relate to memory safety. This situation underscores the pressing issue of outdated design philosophies that struggle to adapt to today's interconnected digital framework.

Highlighting AI-specific Risks

In his presentation, Shibata also introduced the emerging risk of 'prompt injection' unique to the era of generative AI. He advocated for applying the principle of 'minimal authority' even within AI systems to enhance security measures preventively rather than reactively.

To equip students with actionable strategies, Shibata outlined five practical steps to mitigate risks, including:

• - Avoiding the reuse of passwords;
• - Implementing two-factor authentication;
• - Staying informed about potential security threats;
• - Regularly updating software and systems;
• - Developing a robust understanding of data permissions.

The event was held at the Congress Square Haneda Hall from 11:00 AM to 3:00 PM, offering free entry for attendees. It featured engaging activities such as a cybersecurity-themed mystery-solving game, informational booths from various organizations within the tech and cybersecurity sectors, and a game scenario pitch contest. Notably, the event also highlighted the importance of cybersecurity, with the Ministry of Defense setting up its own booth to advance public understanding.

Comments from Shihiki Shibata

Reflecting on the importance of his session, Shibata remarked, “I aimed to shift the focus from 'how can we prevent attacks?' to 'why do attacks persist?' In an age where generative AI is rapidly becoming commonplace, we are increasingly required to entrust more authority and data to digital platforms. Thus, effective security needs to be embedded from the design phase onward, rather than relying solely on user vigilance.”

He emphasized that such principles guide the development of the services provided by Kort Valuta. Among these, the 'TwooCa' platform combines digital ID, payment systems, and AI technology, aiming to create a secure infrastructure for its users. Shihiki expressed hope that students participating in the session would transition from being 'users who use safely' to 'individuals committed to creating a safe society', fostering dialogue about the future of the digital world.
