Doha:Bangkok A recent cyberattack on refrigeration systems across multiple supermarkets in eight European countries has raised significant concerns about the security of operational technology (OT) systems. The attack, which caused damage to frozen food and forced store shutdowns, has puzzled experts and the public alike due to the absence of political motives, ransom demands, or government-shaming statements from the hacker group.
According to Thai News Agency, Dr. Prinya Hom-anek, a member of the National Cyber Security Council (NCSC), analyzed the incident as a demonstration of hackers' capabilities and a warning about vulnerabilities in OT systems. He highlighted the risk posed by centralized management systems that allow headquarters to control equipment settings across all branches. If compromised, these systems could enable hackers to inflict widespread damage almost instantly.
The threat is not confined to supermarkets alone but extends to various Internet of Things (IoT) devices, including security cameras, smart TVs, and hospital systems, necessitating a comprehensive reassessment of security measures.
In addition to the supermarket hacking, the retail and e-commerce sectors are facing a surge in cyber threats, as highlighted in a Kaspersky Security Bulletin report. The report indicates that 22% of devices in this sector face threats, with ransomware attacks increasing dramatically. Artificial intelligence (AI) is a major accelerator in these attacks, enabling hackers to exploit vulnerabilities at unprecedented speeds.
The impact of these cyber threats has prompted warnings from governments and Thai authorities, emphasizing the importance of preparedness for crises. The "72-hour survival rule" is recommended, encouraging individuals to stockpile essentials like clean water, food, and medications to endure potential disruptions.
Dr. Prinya advocates for a resilience mindset and the preparation of a "Plan B" for digital life. He emphasizes the need for contingency plans in the event of internet or digital service outages, drawing on his personal experience of digital disconnection in remote areas as a lesson in self-reliance and preparedness.
