Increasing Cybersecurity Risks for IoT and Blockchain Systems: A Growing Concern
As the digital landscape continues to evolve, so too do the threats that lurk within it. Cybersecurity experts are increasingly sounding the alarm about the rising risks associated with Internet of Things (IoT) devices and blockchain systems. With cyber threats such as ransomware, information spoofing, and targeted attacks escalating in both frequency and sophistication, organizations must remain vigilant and proactive in their cybersecurity strategies.
The Evolving Threat Landscape
A recent report from Viettel Cyber Security highlights several emerging cyberattack trends that organizations need to prepare for. Among these trends is the increasing use of artificial intelligence (AI) by cybercriminals to launch complex and stealthy attacks. AI technologies enable hackers to develop sophisticated malware and execute convincing voice, image, and video spoofing campaigns, making it more challenging for organizations to detect and respond to threats.
Additionally, the rise of Ransomware-as-a-Service (RaaS) has made ransomware attacks more accessible to a broader range of cybercriminals. This model allows even those with limited technical skills to launch devastating attacks, further complicating the cybersecurity landscape. As ransomware attacks evolve, they are likely to incorporate advanced encryption techniques that make recovery more difficult for victims.
The Threats to IoT and Blockchain
The increasing focus on IoT and blockchain systems as new targets is particularly concerning. IoT devices, often characterized by their limited security features, present an attractive entry point for cybercriminals. With the proliferation of connected devices in homes and businesses, the potential for exploitation is vast. Similarly, blockchain systems, while designed to be secure, are not immune to attacks. The rising value of cryptocurrencies has led to an increase in cyber theft, with hackers targeting digital wallets, exchanges, and even ransomware payments made via cryptocurrency.
Moreover, fileless attacks—where malware operates directly from system RAM or utilizes built-in tools like PowerShell—are becoming more prevalent. These attacks are harder to detect and mitigate, posing a significant challenge for cybersecurity teams.
The Role of AI and Quantum Computing
The National Cyber Security Association (NCA) has projected that Vietnam will face severe cybersecurity challenges in 2025, particularly in light of economic, political, and diplomatic events. The NCA foresees that AI-enhanced attacks will significantly increase the exploitation of vulnerabilities, especially in critical infrastructure. The development of supercomputers and quantum chips introduces both opportunities and challenges, particularly regarding the security of encryption algorithms.
As the value of cryptocurrencies continues to rise, the potential for cyber theft will likely increase. This trend underscores the need for organizations to bolster their cybersecurity measures to protect against evolving threats.
Enhancing Cybersecurity Readiness
In response to these mounting challenges, experts emphasize the importance of investing in advanced security technologies. Vu Ngoc Son, Chief Technology Officer at NCA, advocates for the integration of AI and threat intelligence into cybersecurity operations. This approach enables organizations to detect threats early and respond more swiftly.
Nguyen Van Quan, Deputy Head of Technical Division at VNCS, highlights the necessity of incident response planning, risk management, and close coordination with authorities. Organizations should develop comprehensive incident response scenarios and allocate dedicated resources for system protection.
Strategic Priorities for Cyber Resilience
To navigate the increasingly complex cybersecurity landscape, experts from Viettel Cyber Security recommend that businesses and organizations focus on five strategic priorities:
-
Continuous Monitoring and Incident Response: Implement 24/7 cybersecurity monitoring using tools like Threat Intelligence, Endpoint Detection and Response (EDR), and Network Security Monitoring (NSM) to detect and respond to threats in real-time.
-
Modern Governance Model: Apply zero-trust principles to IT and operational technology (OT) infrastructure, manage privileged accounts strictly, and separate IT and operational networks to minimize attack risks.
-
Regular Vulnerability Management: Conduct periodic assessments, prioritize critical vulnerability patching, and manage risks stemming from supply chain partners.
-
Investing in Advanced Security Technologies: Adopt solutions like External Attack Surface Management (EASM), Security Operations Centers (SOC), and DDoS mitigation techniques to safeguard information assets.
- Building a Security-Aware Culture: Regularly train employees on cybersecurity awareness, conduct incident response drills, and establish strict access control policies following the principle of least privilege.
By implementing these strategic measures, organizations can mitigate the impact of cyberattacks, ensuring business continuity and minimizing risks related to data security.
Conclusion
As cyber threats continue to evolve, the risks associated with IoT and blockchain systems are becoming increasingly pronounced. Organizations must prioritize cybersecurity readiness and adopt a proactive approach to safeguard their digital assets. By focusing on continuous monitoring, modern governance, vulnerability management, advanced technologies, and fostering a security-aware culture, businesses can better navigate the complexities of the digital landscape and protect themselves against the ever-growing threat of cybercrime.
