◾️Lecture Content
Shipping Halted + 1.7 Billion Yen Loss from a Cyberattack.
~Real Lessons from Returning from Despair + Building the 'Ultimate Plan B' that Decides the Fate of EC Operators~
In 2024, Kantsu suffered a massive ransomware attack that resulted in a critical crisis where EC shipping operations completely stopped, leading to a 1.7 billion yen loss.
In this session, we will candidly share the gruesome reality of the damage and the real behind-the-scenes story—rarely covered by the media—of how we managed to recover our business. In the EC business, '100% defense' is impossible. We will convey the critical importance of a 'recovery system (Plan B)' to minimize business suspension in the event of a cyberattack breach, along with practical preparations that can be implemented starting tomorrow.
◾️Key Points of This Session:
Practical Guidelines for Business Continuity Learned from the 'Reality' of the Damage
By understanding the 'vivid reality of a cyberattack frontline' that cannot be found in manuals, we aim to foster a true sense of crisis that organizations must possess. For EC operators facing common challenges—such as being unable to imagine the specific situation of a ransomware infection, or struggling to implement measures due to a lack of budget or IT personnel—we will present the 'shortest route to recovery that minimizes business suspension' based on our real experience of surviving a 1.7 billion yen loss. We will also provide concrete tips on how to persuade top management to solidify defenses.
