Background

Since the U.S. and allied export restrictions in October 2022, which curtailed China’s access to advanced semiconductor equipment, Beijing has prioritized cyberespionage to close technological gaps. The Netherlands—home to ASML, a leading supplier of extreme ultraviolet lithography systems—reported escalating Chinese espionage aimed at semiconductor firms and critical raw material suppliers. Chinese hacking groups, often state-affiliated, have long targeted Western and East Asian semiconductor hubs to steal intellectual property and glean insights into microfabrication processes. Taiwan’s industry, centered in Hsinchu Science Park, stands at the epicenter of these efforts, with local prosecutors uncovering covert recruitment of engineers by Chinese firms. Collectively, these activities form part of a broader campaign to achieve semiconductor self-sufficiency and mitigate the impact of export controls. (reuters.com, en.wikipedia.org, osintteam.blog)

Findings

1. Surge in Targeted Espionage Campaigns

Since early 2025, Dutch military intelligence has documented a marked uptick in intrusion attempts against semiconductor firms, with Chinese actors probing for vulnerabilities in corporate networks and R&D labs. These efforts align with China’s broader push to circumvent export restrictions and accelerate domestic chip innovation. Parallel reporting indicates that Taiwan’s semiconductor research centers were attacked over 2.4 million times per day in 2024, doubling the volume from the previous year. (reuters.com, en.wikipedia.org)

CrowdStrike’s 2025 report corroborates these trends, noting a 150% jump in Chinese cyberespionage operations, with semiconductor targets experiencing up to a 300% increase in attack frequency. APT41 and other PLA-linked groups employed spear-phishing campaigns that delivered Cobalt Strike beacons and custom PlugX variants to gain initial footholds.

2. Advanced Persistent Threat Tactics

Chinese threat actors have refined their tactics to avoid detection. Using living-off-the-land techniques—leveraging legitimate system tools like PowerShell and WMI—groups such as Volt Typhoon (also known as Dev-0391) embed deeply within target networks. Volt Typhoon’s campaigns prioritize stealth, focusing on credential harvesting and lateral movement across semiconductor supply chains, including Tier-2 vendors in North America and Europe. (en.wikipedia.org)

In addition, Chinese-affiliated groups exploit vulnerabilities in third-party service providers to bypass direct defenses. For example, the 2024 Singtel breach—attributed to Volt Typhoon—involved weaponized exploits targeting telecom infrastructure, which can indirectly compromise semiconductor clients reliant on those networks. (en.wikipedia.org)

3. Human Intelligence and Recruitment

Beyond pure cyber operations, Taiwan’s MJIB uncovered illegal recruitment of Taiwanese engineers by Chinese semiconductor firms attempting to obtain trade secrets. Prosecutors found that eight Chinese entities concealed their identities to lure talent from Hsinchu Science Park, evidencing a hybrid espionage approach combining cyber intrusion with human intelligence. This front-end recruitment feeds back into cyber campaigns, as newly hired engineers may inadvertently facilitate data exfiltration. (en.wikipedia.org)

4. Countermeasures and Denials

In response to public allegations, China’s Foreign Ministry denied any state-sponsored espionage, asserting that its technological advancements are homegrown. Nevertheless, Dutch and Taiwanese authorities continue to bolster protective measures: The Netherlands is enhancing industry-wide cybersecurity standards, while Taiwan has implemented stricter supply chain audits and real-time monitoring of network traffic in research facilities. (reuters.com, osintteam.blog)

Analysis

The convergence of increased intrusion attempts, advanced TTPs from groups like APT41 and Volt Typhoon, and parallel human recruitment efforts underscores a multi-layered Chinese strategy to acquire semiconductor IP. By targeting both high-value R&D centers in Taiwan and critical equipment suppliers in the Netherlands, Beijing aims to erode Western technological advantages and accelerate its own production capabilities. (osintteam.blog, merics.org)

Stealthy living-off-the-land techniques complicate detection and remediation, forcing defenders to distinguish between legitimate administrative tools and malicious activity. The scale of daily intrusion attempts in Taiwan suggests substantial resource allocation by Chinese operators, indicating that semiconductors remain a top strategic priority. (en.wikipedia.org, en.wikipedia.org)

Furthermore, the integration of human intelligence—recruiting engineers under false pretenses—amplifies cyber gains by providing insider knowledge of proprietary processes. Combined, these TTPs threaten to widen China’s R&D gap, challenging the effectiveness of export controls and bilateral technology restrictions. (en.wikipedia.org, en.wikipedia.org)

Implications

• For Western Manufacturers: Companies in the U.S., Europe, and East Asia must assume persistent targeting by sophisticated Chinese actors. Failure to detect and isolate compromised credentials or contractor backdoors could lead to irreparable IP loss and erode competitive advantage.
• For National Security: Semiconductor technology underpins both civilian and military systems. Chinese acquisition of advanced chip designs may enable acceleration of AI, quantum computing, and advanced weapon system development, shifting the balance of power.
• For Supply Chain Resilience: Overreliance on a handful of global suppliers (e.g., ASML in the Netherlands) creates single points of failure. Disruptions from cyber incidents can cascade across automotive, telecom, and defense industries, prompting urgent diversification.
• For Cybersecurity Policy: The scale and sophistication of Chinese campaigns necessitate enhanced international cooperation on threat intelligence sharing, harmonized cybersecurity standards, and coordinated sanctions against state-affiliated hacker groups.
