The recent ransomware attacks targeting Japan’s prominent companies, Muji and Asahi, have sent shockwaves throughout the corporate world, laying bare the vulnerabilities even well-established firms face. Muji’s decision to halt its domestic online shopping service following an attack on its delivery partner Askul is not just a story about a cyber incident; it’s a wake-up call for everyone who assumes their systems are impervious to threats that lurk in the digital shadows.
From the perspective of businesses managing critical logistics and e-commerce operations, the ramifications of such an incident are profound. Imagine the chaos when your entire order processing pipeline grinds to a halt because an external partner falls victim to malware. This is exactly what happened when ransomware infiltrated Askul’s systems late on October 19, leaving Muji scrambling and ultimately forcing the suspension of its online shop. The chilling fact? The resumption of operations remains uncertain.
It’s easy to imagine the frustration rippling through Muji’s executives and customer service teams. Every delayed package and unmet customer expectation chips away at your brand’s reputation. When Ryohin Keikaku highlighted that their shares dipped significantly after the announcement, it wasn’t just numbers shifting on the stock market. It was a tangible representation of lost confidence—an emotional toll on both shareholders and consumers alike.
And the storm doesn’t end there. The attack seems linked in spirit, if not in direct connection, to another ongoing ransomware siege that has crippled Japanese brewing giant Asahi since late September. Asahi, renowned for its flagship beer Asahi Super Dry, is fighting a battle on multiple fronts—systematic order processing down, partial reliance on manual operations, and the postponement of financial disclosures. The tangible loss transcends money—it threatens the trust that customers place in the regularity and reliability of their daily staples.
It’s impossible to discuss these incidents without acknowledging the hackers behind them. The Qilin group, believed to operate out of Russia, stands accused—and perhaps even openly admits—to orchestrating the attack. This raises alarming questions about geopolitical influences spilling into the private sector, turning routine corporate infrastructure into a battleground for state or criminal agendas. The ambiguity around their demands or motives only amplifies the fear of the unknown. What can businesses do when the adversary remains faceless and unpredictable?
Every entrepreneur or SME leader I’ve conversed with in Singapore echoes a shared angst—that it can happen to anyone. The digital age, while enabling unparalleled growth and connectivity, also exposes us to invisible vulnerabilities. If a Japanese retail titan with vast resources and a trusted name can be brought to its knees, it underscores a critical truth: cybersecurity defenses must evolve relentlessly.
What can we learn from Muji and Asahi’s harrowing experiences? Firstly, robust vetting and continuous monitoring of partners’ cybersecurity postures are non-negotiable. You might have the most ironclad security measures internally, but if your suppliers or logistics partners carry cracks in their systems, those gaps will quickly transform into your Achilles’ heel.
Secondly, incident response must be proactive rather than reactive. Waiting for daylight after a 9pm infiltration is not a strategy—it’s a vulnerability exploit. Businesses must cultivate incident detection strategies that catch intrusions early, minimize damage swiftly, and communicate transparently to maintain customer trust.
Thirdly, contingency planning cannot simply exist on paper. Muji’s indefinite suspension of operations highlights how unprepared firms can be for these eventualities. Every business, regardless of scale, needs a practical and tested continuity plan that accounts for cyber disruptions, especially those stemming from third-party relationships.
Lastly, there’s an emotional dimension often overlooked—the impact on staff and customers. Employees face the dual burden of operational chaos and the stress of responding to a crisis they might feel powerless to control. Customers, meanwhile, experience frustration and uncertainty, eroding the emotional bonds cultivated over years of loyalty.
Personally, dealing with SMEs that have faced similar digital breaches, I witnessed firsthand the devastating ripple effects across business operations, customer confidence, and internal morale. Crying out for systemic change, these businesses taught me that cybersecurity isn’t just IT’s responsibility—it’s a core element of strategic leadership and corporate culture.
It’s tempting to see these ransomware episodes as distant news, isolated incidents somewhere in Tokyo’s corporate ecosystem. Yet, the reality is stark: they illustrate a global truth that no business—no matter how big or small—is immune. Lessons from Muji and Asahi must trigger immediate, forceful action in Singapore and beyond.
Prepare rigorously, demand transparency down your supply chain, and embrace a mindset where digital threats are treated with the urgency they deserve. This isn’t merely about protecting data or operations; it’s about preserving your company’s future, customer trust, and the hard-won credibility that takes years to build and seconds to dismantle.
