Essential Insights
- Kantsu faced a severe cyberattack that incapacitated its systems, prompting the decision to discard and rebuild a new, secure system at a cost of ¥700 million (~ US$4.6 million), prioritizing speed over thorough investigation.
- The company consolidated security services into one firm, selecting a venture company for rapid response and flexible problem-solving capabilities, emphasizing the importance of specialized strengths.
- Despite having cyber insurance, Kantsu faced delays and uncertainties in insurance claims, ultimately suffering a total financial loss of ¥1.7 billion (~ US$11.1 million), including system renewal and partner compensation.
- President Tatsujo stresses that cyberattack prevention is impossible; preparedness, including incident manuals and recovery plans, is crucial for effective response and minimizing damage.
The Core Issue
Kantsu, a logistics company heavily reliant on digital systems, faced a devastating cyberattack that crippled its operations, including critical robotic process automation (RPA) and order management systems. The attack exposed significant vulnerabilities, forcing the company’s leadership, led by President Tatsujo, to make a bold decision: abandon the outdated infrastructure entirely and build new, more secure systems from scratch. Recognizing that restoring the compromised systems would take over a month with no guarantee of safety, Tatsujo prioritized speed and security over caution, opting to completely discard the compromised systems at a cost of ¥700 million (about US$4.6 million). This aggressive approach was motivated by the urgent need to prevent further customer exodus and ensure stability, even though it meant risking further financial strain and losing valuable data.
The incident was reported by Kantsu’s internal leadership and was discussed openly with external partners and security experts, who emphasized that the company’s swift move was necessary despite the financial and operational challenges. President Tatsujo highlighted the importance of pre-planning, such as having incident manuals and recovery plans, acknowledging that cyberattacks are inevitable and that quick, decisive action is crucial to minimize damage. Overall, the attack resulted in an estimated total loss of ¥1.7 billion (approximately US$11.1 million), including costs for system overhaul and compensations to affected partners, but it ultimately led to a faster recovery and a renewed focus on cybersecurity preparedness.
Risk Summary
Cyber risks pose severe threats to organizations like Kantsu, as cyberattacks can disable critical systems and jeopardize customer data, leading to extensive financial losses, operational disruptions, and reputational damage. In Kantsu’s case, a devastating cyberattack incapacitated essential logistics and order systems, forcing the company to abandon its old infrastructure entirely—costing ¥700 million ($4.6 million)—and to rapidly build a new, more secure system. The attack also complicated insurance claims, resulting in a total financial loss of ¥1.7 billion ($11.1 million) which included system overhaul costs and compensation to partners. Such attacks reveal the profound impact of cyber risks, emphasizing the necessity for proactive incident preparation, swift response plans, and sensitive balance between investigation and speedy recovery to mitigate damages and preserve trust.
Possible Next Steps
In the high-stakes world of cybersecurity, promptly addressing ransomware incidents is critical to safeguarding business continuity and maintaining stakeholder trust. When faced with an attack like Kantsu’s, swift and effective response can mean the difference between resilience and devastating losses.
