Escalating Chinese cyberattacks on Japan, US defences: A strategic threat to global security

In recent years, a troubling rise in cyberattacks targeting Japan’s defence, aerospace, and advanced technology sectors has raised alarm bells among experts.

These attacks, many attributed to Chinese state-backed groups, signal a broader geopolitical strategy aimed at undermining the technological and military strengths of democratic nations, particularly the United States.

The Japanese National Police Agency (NPA) has documented a staggering 210 cyberattacks from China since 2019, underscoring the urgency with which Japan and its allies must address this growing cybersecurity threat.

China’s increasing involvement in cyberattacks against Japan aligns with a larger strategic approach to challenging the West’s technological and military dominance.

Cyberattacks, often conducted by groups with ties to the Chinese government, have been reported to target critical infrastructure, intellectual property, and military secrets.

This is particularly concerning for Japan, which is home to some of the most advanced defence systems, aerospace technologies, and cutting-edge innovations in the world.

Japan’s defence and aerospace sectors are heavily integrated into global security frameworks, with close ties to the United States and other Western powers.

Any disruption to these sectors through cyberattacks could have ripple effects, not only affecting Japan’s national security but also that of its allies, including the U.S.

These cyberattacks are not just a matter of theft but represent a broader effort to weaken the technological foundations that underpin Japan’s defence capabilities.

China’s role in state-sponsored cyber espionage has been well documented.

The Chinese government has been accused of leveraging cyber capabilities to steal sensitive information, intellectual property, and defence secrets from various nations, including Japan.

These attacks are often carried out by advanced persistent threat (APT) groups, which are highly skilled and well-funded.

These groups use sophisticated techniques, such as spear-phishing, malware, and zero-day vulnerabilities, to infiltrate networks and exfiltrate valuable data without detection.

Experts suggest that China’s long-term strategy involves eroding the technological edge of its rivals, particularly the United States, which has historically led in fields such as aerospace, artificial intelligence, and military technologies.

By stealing or disrupting these innovations, China seeks to level the playing field, or even gain an upper hand in military and technological competitions.

In the case of Japan, the targeted sectors—defence, aerospace, and advanced technologies—are vital to the country’s self-defence and economic prosperity.

Japan’s defence industry is not only a national priority but also a critical component of regional security.

Japan has historically maintained a pacifist constitution, but in recent years, the nation has ramped up its defence capabilities in response to growing threats in the Asia-Pacific region, particularly from China and North Korea.

This shift has led to the development of advanced technologies, including cutting-edge fighter jets, radar systems, and missile defence platforms.

The aerospace sector is equally significant, with Japan’s leading aerospace companies contributing to both civilian and military aviation.

Japan’s defence ties with the United States, particularly through joint projects like the F-35 fighter jet, have further enhanced the country’s technological prowess.

Chinese cyberattacks targeting these industries seek not only to steal intellectual property but also to disrupt critical supply chains and manufacturing processes that support Japan’s defence and aerospace initiatives.

Furthermore, Japan is heavily invested in the development of advanced technologies such as artificial intelligence, robotics, and space exploration.

These fields have military applications, making them attractive targets for espionage.

Disrupting or stealing breakthroughs in these areas could provide China with a competitive advantage, both economically and militarily.

The Japanese NPA’s report revealing 210 state-backed cyberattacks from China since 2019 paints a grim picture of the rising threat.

This figure is not just a reflection of the increasing frequency of attacks, but also the growing sophistication of cyber-espionage tactics employed by Chinese-backed actors.

The NPA has noted that the attacks primarily targeted sectors related to Japan’s national defence and aerospace capabilities.

The methods used by the attackers often involve advanced malware and phishing schemes designed to infiltrate secure networks and systems.

Once inside, the cybercriminals can either steal data or cause significant disruption.

In some cases, these attacks may remain undetected for long periods, allowing China to gather sensitive information without raising alarms.

The NPA’s findings underscore a key concern for Japan’s security: the vulnerability of its most critical sectors to foreign cyberattacks.

As Japan continues to modernise its defence infrastructure and collaborate with the U.S. and other democratic nations, the need to safeguard sensitive information and technologies becomes more pressing.

This is particularly important in light of Japan’s evolving security landscape, where cyberattacks are increasingly seen as an extension of traditional warfare.

The consequences of cyberattacks on Japan’s defence and aerospace sectors can be far-reaching.

A successful cyberattack could lead to the loss of critical defence data, including blueprints for advanced weapon systems or details of joint defence projects with the United States.

If Chinese-backed hackers were to gain access to Japan’s missile defence systems or stealth aircraft designs, it could undermine Japan’s ability to defend itself, especially in a regional conflict involving China or North Korea.

The theft of intellectual property related to aerospace technologies, such as advanced aircraft engines or radar systems, could also significantly damage Japan’s position in the global aerospace market.

This would not only affect Japan’s defence industry but also its economic standing, as many of its aerospace firms are major exporters to both military and commercial markets worldwide.

Moreover, the disruption of advanced technology sectors—such as those focused on artificial intelligence or quantum computing—could hinder Japan’s technological growth.

Such attacks may delay the development of critical innovations that have both military and civilian applications, placing Japan at a technological disadvantage compared to other nations, including China.

The rising threat of Chinese cyberattacks on Japan is not just a bilateral issue but a global concern.

As a key player in the Asia-Pacific region, Japan’s security is intertwined with that of its allies, particularly the United States.

Any disruption to Japan’s defense or technological sectors could have severe consequences for regional stability and security.

This is particularly true as Japan continues to play a pivotal role in countering China’s growing military presence in the region.

The increasing frequency of cyberattacks on Japan also serves as a warning to other democratic nations.

If China’s cyber capabilities go unchecked, the risks to global security will continue to grow.

As nations like the U.S., Japan, and others in the West invest in next-generation technologies, it is imperative that they also prioritise cybersecurity to protect their technological and military strengths.

The rise in Chinese cyberattacks on Japan’s defence, aerospace, and advanced technology sectors highlights the vulnerability of nations heavily invested in cutting-edge military and technological advancements.

The 210 documented cyberattacks since 2019 reflect not only a growing threat but also a strategic effort by China to undermine the technological edge of democratic nations.

As Japan and its allies grapple with these challenges, the need for robust cybersecurity measures has never been more urgent.
