Introduction
The Czech Republic is sounding the alarm over the growing risks posed by Chinese-linked technologies. From cloud platforms to connected vehicles, and from surveillance cameras to large language models, the penetration of Chinese-made systems into critical sectors like healthcare, transport, energy, and government has reached alarming levels. The country’s National Cyber and Information Security Agency (NUKIB) recently issued a stern warning, stressing that trust in suppliers is now a matter of national security. The warning comes in the wake of confirmed cyber espionage campaigns attributed to APT31, a Chinese state-backed group, targeting Czech institutions and NATO allies.

The Czech Republic’s National Cyber and Information Security Agency (NUKIB) has issued a formal warning about the growing risks associated with Chinese-made technologies. The agency highlights that Chinese products—including IP cameras, photovoltaic inverters, smart meters, healthcare devices, smartphones, cars, and even AI language models—are increasingly integrated into critical national infrastructure. These devices often transmit data abroad or are remotely controlled by suppliers, leaving sensitive systems vulnerable to manipulation and espionage.
NUKIB stressed that current infrastructure relies heavily on cloud storage and remote updates, giving suppliers significant power to influence operations. This makes trust in the supplier essential. The agency also noted that many of these devices are managed from China, which grants Chinese entities the ability to access, manipulate, or disrupt critical systems.
The warning comes amid heightened geopolitical tensions following cyberattacks linked to APT31, a well-known Chinese cyber espionage group also called Zirconium or Judgment Panda. In 2022, APT31 hackers infiltrated a Czech ministry’s unclassified system, remaining undetected for a prolonged period. By May 2025, Czech authorities publicly condemned China, pointing to a “high degree of certainty” in their attribution of the attack.
European and NATO allies expressed solidarity with the Czech Republic, with the EU issuing a separate statement condemning China’s cyber activities. Officials emphasized that no state should allow its territory to be used for malicious cyber operations. APT31 has a long history of stealing sensitive political, military, and industrial data from Europe, North America, and Asia.
NUKIB further underscored that in China, laws and policies allow the state to compel private companies to cooperate in espionage, making any reliance on Chinese technology inherently risky. While the warnings under the Czech Cybersecurity Act require critical organizations to act, individual citizens are also urged to be cautious about the technologies they adopt and the data they share.
What Undercode Say:
The Czech Republic’s warning reflects a broader global reckoning with technological dependencies that extend beyond economic convenience. In today’s hyperconnected world, the supplier of your software, cloud service, or even your smart meter may hold the keys to your national security. The Czech case underscores a critical reality: in geopolitics, technology is no longer just a tool—it is a weapon.
APT31’s operations against Czech ministries fit into a wider pattern of state-sponsored cyber campaigns that weaponize digital dependency. When cameras, cars, and even healthcare devices are tied to foreign infrastructure, the door is left open for cyber infiltration, remote manipulation, or outright disruption. This goes beyond espionage—it’s about leverage. Nations can be coerced not by soldiers, but by switches and servers.
What makes this particularly urgent is the nature of modern infrastructure. Cloud-based systems, remote diagnostics, and software updates have become the backbone of everyday services. But these features, which promise efficiency, also create backdoors for exploitation. Once trust in a supplier is compromised, the consequences ripple through healthcare delivery, energy grids, transport safety, and even government decision-making.
The Czech warning is not isolated—it mirrors concerns raised in the US, UK, and other EU nations. For example, debates around Huawei’s role in 5G infrastructure raised similar fears: if a foreign state can access data or shut down networks, then sovereignty itself is at risk. The Czech stance is particularly bold given its size and dependence on global trade, suggesting that smaller states may actually be more exposed to these risks than larger powers.
At the heart of the matter lies a paradox. Global supply chains thrive on efficiency and cost-effectiveness, but security often takes a back seat. Chinese tech firms offer competitive pricing, rapid deployment, and advanced features—an irresistible package for cost-conscious governments and companies. Yet, this very convenience can come at the price of long-term security and autonomy.
It is also telling that APT31 remained undetected for years within a Czech ministry’s network. This illustrates not only the sophistication of Chinese cyber units but also the difficulty in defending against them. Detection is hard, attribution is harder, and political consequences are the hardest of all. The EU’s strong support for Czechia shows a growing recognition that cyberattacks are not isolated incidents but attacks on the collective resilience of democracies.
For businesses and citizens, the warning is a reminder that security is not solely a government issue. The devices we use—from smart meters to connected vehicles—are potential gateways to data exploitation. Awareness and scrutiny must extend to consumer choices, not just institutional policies. Trust in technology suppliers should now be weighed as heavily as trust in financial institutions or defense partners.
Czechia’s approach suggests a new phase in cyber defense: proactive, transparent, and collective. By naming the risks and linking them to geopolitical actors, Prague has shifted the conversation from vague “cyber hygiene” to explicit national security strategy. This clarity could set a precedent for other EU members facing similar risks.
Ultimately, the issue is about sovereignty in the digital age. Just as nations once fought to control their borders, they must now secure their data flows and technological dependencies. The Czech case is a warning not just about China but about the fragility of all interconnected systems when supplier trust is compromised. In a future where wars may be fought as much with code as with weapons, such warnings cannot be ignored.
🔍 Fact Checker Results
✅ APT31 is a documented Chinese cyber espionage group active for over a decade.
✅ The Czech government and EU have officially condemned Chinese-linked cyberattacks.
✅ NUKIB’s warning about Chinese tech influencing critical sectors is based on verified risk assessments.
📊 Prediction
The Czech Republic’s firm stance will likely inspire other EU states to reassess their technological dependencies. Expect stricter procurement rules, diversification of suppliers, and increased investment in European-made technologies. In the next five years, cybersecurity will no longer be treated as a technical afterthought but as a central pillar of foreign policy and national defense.
