These developments underscore Taiwan's persistent challenges from both conventional and unconventional threats, necessitating robust defense modernization and enhanced cybersecurity measures.

Key Security Developments

• Chinese Military Activities and "Area Denial" Drills
  On November 5, Taiwan's Ministry of National Defense (MND) reported tracking 21 Chinese military aircraft, eight naval vessels, and eight official ships, with 19 aircraft crossing the Taiwan Strait median line in various air defense identification zones. This activity was part of a broader, unannounced Chinese military exercise simulating the surrounding and isolating of Taiwan, involving over 100 People's Liberation Army Navy (PLAN) and China Coast Guard (CCG) vessels in the West Pacific, including the Liaoning carrier strike group. Taiwan's Defense Minister Wellington Koo confirmed on November 10 that China is conducting "area denial" drills in the Western Pacific, involving an aircraft carrier and other naval formations, which Taiwanese officials interpret as rehearsals for a potential maritime blockade using military, paramilitary, and civilian assets.

• International Condemnation of Chinese Actions
  G7 Foreign Ministers, following a meeting in Paris on November 11, issued a joint declaration expressing concern over China's increasingly assertive actions in the waters east of Taiwan. They stressed the importance of maintaining peace and stability across the Taiwan Strait and reaffirmed their opposition to any unilateral attempts to change the status quo, particularly through force or coercion. This statement reflects growing international apprehension regarding Beijing's military activities near Taiwan.

• Taiwan Strengthens Laws Against Transnational Repression
  On November 5, Taiwan announced plans to strengthen its laws against transnational repression, specifically targeting efforts by Beijing to intimidate or harm individuals in Taiwan through proxies. Justice Minister Cheng Ming-chien indicated that the government is working to amend the Anti-Infiltration Act to create new offenses specific to transnational repression and allow for the confiscation of assets tied to such operations. This move comes after several high-profile incidents exposed gaps in the existing legal framework.

• Taiwan's 2027 Defense Budget Focuses on Deterrence
  Taiwan's Defense Ministry delivered its 2027 budget plans to lawmakers, emphasizing a strategy to deter Chinese aggression. The plans include advancing technological capabilities, expanding domestic weapons production (such as drones, armored vehicles, and missiles with an investment exceeding $7 billion USD), and acquiring critical supplies from the United States. The ministry also highlighted efforts to strengthen vetting processes to combat Chinese espionage, with 73 individuals indicted in espionage cases so far this year, up from six in 2020.

• AI-Assisted Cyberattacks Affect Over a Million Records
  The Ministry of Digital Affairs (MODA) reported on November 11-12 that nearly half of recent cyberattacks targeting more than 10 businesses and online platforms in Taiwan involved artificial intelligence (AI), affecting over 1 million personal records. These attacks, which began around mid-September, compromised names, phone numbers, email addresses, and order details, with some traffic originating from Hong Kong and utilizing ARTEX, a Chinese-developed automated vulnerability scanning tool. MODA officials noted that AI helps hackers quickly find and exploit vulnerabilities like weak passwords and unpatched software.

• TSMC Cloud Vendor Data Breach
  On November 12, Taiwan Semiconductor Manufacturing Company (TSMC) confirmed that information belonging to 46,000 current and former employees was placed on external websites without authorization. While TSMC stressed there was no evidence of its own systems being breached, it attributed the leak to a cloud service provider. The compromised data, including names, national ID numbers, addresses, and bank account details, was offered for sale on underground forums for 3 Bitcoin (approximately $220,000 USD), posing risks of identity theft and targeted cyberattacks.

• Din Tai Fung Online Shop Data Breach
  Din Tai Fung, a prominent restaurant chain, suspended its online shop operations on November 10 following a suspected customer order data leak. Customers in Taiwan reported receiving scam emails that accurately matched their names and order details, indicating a breach of personal information. The company initiated an inspection and reported the incident to the police.

• Kang Chiao International School Ransomware Attack
  On November 11, the Linkou campus network of Kang Chiao International School was reportedly hacked with ransomware. Parents subsequently received ransom letters claiming that sensitive family information had been stolen and leaked. The school immediately shut down its internet and reported the incident to the police.

• Taiwan-Based Hacker Uses AI Agents for Data Theft
  Acronis's Threat Research Unit reported on November 9 that a single attacker based in Hualien City, Taiwan, used AI agents to steal emergency dispatch records covering seven Taipei districts. The attacker also exploited a Taipei fire department platform, exposing patient data from 2018, including ECG readings and ambulance video footage, without requiring a login. This individual targeted hundreds of organizations in at least 11 countries, with Taiwan being the most heavily affected.

• Bomb Threats to Italian Schools with Suspected Taiwan Link
  On November 11, hundreds of schools across Italy, along with some in Scotland and Northern Ireland, received bomb threats via email. A Milan headteacher noted that the sender's email address was classified as spam by a student at a Taiwanese university, suggesting a potential link to a hacked account in Taiwan. Italian Prime Minister Giorgia Meloni stated that checks found no concrete danger, and the threats appeared to be a strategy to cause alarm.

Cyber Threat Landscape

Taiwan's cyber landscape was highly active during this period, characterized by a significant volume of data breaches and the increasing sophistication of AI-assisted attacks. The Ministry of Digital Affairs (MODA) disclosed that nearly half of the recent cyberattacks targeting over 10 Taiwanese businesses and online platforms involved artificial intelligence, impacting more than 1 million personal records. These attacks, which compromised names, phone numbers, email addresses, and order details, showed some traffic originating from Hong Kong and utilized ARTEX, a Chinese-developed automated vulnerability scanning tool. Officials noted that AI significantly accelerates the exploitation of security vulnerabilities such as weak passwords and unpatched software.

Notable incidents included the suspension of Din Tai Fung's online shop due to a suspected customer order data leak, leading to targeted scam emails. The Kang Chiao International School's Linkou campus also suffered a ransomware attack, resulting in parents receiving ransom letters and personal data leakage. Furthermore, TSMC confirmed a data leak of 46,000 employee records from a cloud service provider, though its internal systems remained unbreached. Separately, Acronis's Threat Research Unit identified a Taiwan-based individual in Hualien City who used AI agents to steal emergency dispatch records from seven Taipei districts and accessed patient data from a Taipei fire department platform. The government's response includes urging businesses to report breaches within 72 hours and submit improvement plans within one month.

Background: Threat actors known to target Taiwan include WIZARD SPIDER (Russia-linked), APT27 (China-linked), Earth Lusca (China-linked), ToddyCat, DarkHotel (South Korea-linked), APT1 (China-linked), LOTUS PANDA (China-linked), and BRONZE HIGHLAND (China-linked).

Geopolitical Impact and Regional Dynamics

The period saw a notable escalation in China's "gray zone" tactics, significantly impacting regional stability. Beijing's unannounced large-scale military exercises, simulating the isolation of Taiwan and involving over 100 naval and coast guard vessels in the Western Pacific, demonstrate a clear intent to project power and potentially rehearse for a blockade. Taiwan's Defense Minister Wellington Koo's confirmation of "area denial" drills further underscores China's strategy to deter foreign intervention in a potential conflict. These actions are designed to erode Taiwan's confidence in its own defenses and the willingness of allies like the United States to intervene.

The international community, particularly the G7 foreign ministers, expressed strong concern over China's assertive actions in the waters east of Taiwan, emphasizing the threat to regional stability, freedom of navigation, and the safety of international shipping. This collective diplomatic stance highlights the global implications of cross-Strait tensions and the shared interest in maintaining the status quo. Taiwan's efforts to strengthen laws against transnational repression, allegedly linked to Beijing, also reflect the ongoing political and intelligence competition, where China uses non-military means to exert influence and suppress dissent. The increased cyberattacks, some originating from Hong Kong and using Chinese-developed tools, further complicate the geopolitical landscape, blurring the lines between state-sponsored and criminal activity and adding a significant dimension to hybrid warfare tactics.

EU Relations and Implications

Taiwan's relations with the European Union during this period were primarily shaped by shared concerns over regional stability and an unusual security incident. The joint declaration by G7 Foreign Ministers, which includes France, Germany, and Italy, explicitly condemned China's increasingly assertive actions in the waters east of Taiwan, stressing the importance of peace and stability across the Taiwan Strait. This aligns with the EU's broader interest in maintaining freedom of navigation and a rules-based international order, reinforcing the existing stable EU-Taiwan relationship outlook (assessed August 2026).

A peculiar incident involved bomb threats sent to hundreds of Italian schools, with a suspected link to a hacked account at a Taiwanese university. While Italian authorities deemed the threats hoaxes, this event highlights a potential avenue for malicious actors to create international friction or exploit cyber vulnerabilities with cross-border implications. Such incidents could necessitate closer EU-Taiwan cooperation on cybercrime investigations and digital security, building upon existing EU digital projects like the EU-Taiwan Semiconductor Cooperation and broader cooperation in trade, investment, energy, education, and ICT.

Military and Defense Analysis

Taiwan's military and defense posture during this period was primarily reactive to escalating Chinese pressure while simultaneously pursuing long-term modernization. The People's Liberation Army (PLA) maintained a significant presence around Taiwan, with daily incursions of aircraft and naval vessels, including 21 aircraft and 16 ships tracked on November 5, with 19 aircraft crossing the median line. More concerning were the unannounced "area denial" drills in the Western Pacific, involving an aircraft carrier group and over 100 naval and coast guard vessels, which Taiwan's Defense Minister Wellington Koo identified as rehearsals for a potential maritime blockade. These "quiet exercises" represent a new pattern of high-intensity gray zone operations aimed at demonstrating China's capability to isolate the island.

In response, Taiwan's Ministry of National Defense (MND) deployed aircraft, naval ships, and coastal-based missile systems. The MND's 2027 budget plans underscore a commitment to deterring Chinese aggression through enhanced technological capabilities and expanded domestic weapons production, including drones, armored vehicles, and missiles, with an investment exceeding $7 billion USD. Taiwan is also deepening cooperation with industry and academia on next-generation systems and strengthening its vetting processes to combat Chinese espionage, reflecting a comprehensive approach to national security.

Outlook and Forecast

Short-term trends (1-3 months):
Taiwan can anticipate continued and potentially intensified Chinese military pressure, likely involving more frequent "gray zone" tactics and unannounced exercises around the island and in the Western Pacific. The use of AI in cyberattacks is expected to increase, targeting both government entities and private businesses, leading to more data breaches and sophisticated phishing attempts. Taiwan's efforts to strengthen its anti-infiltration laws will likely proceed, potentially leading to more prosecutions related to transnational repression.

Critical flashpoints and risk areas:
The Taiwan Strait remains the primary flashpoint, with the risk of miscalculation or escalation due to frequent Chinese military incursions. The waters east of Taiwan are also critical, as China's "area denial" drills suggest a focus on potential blockade scenarios, which could disrupt international shipping lanes. Cyber infrastructure, particularly in critical sectors and digital economy businesses, will continue to be a high-risk area, given the recent wave of AI-assisted attacks and data breaches. The upcoming 2026 Taiwan local elections could also serve as a target for disinformation campaigns and cyber interference.

Indicators to monitor:
Key indicators to monitor include the scale, frequency, and geographic scope of People's Liberation Army (PLA) air and naval activities around Taiwan, particularly any further unannounced exercises or deployments of carrier groups. The attribution and sophistication of cyberattacks, especially those employing AI, will be crucial for understanding evolving threat capabilities. Progress in Taiwan's domestic defense production and acquisitions from allies, as well as the effectiveness of its new anti-transnational repression laws, will indicate its resilience. International diplomatic statements, particularly from the G7 and EU, regarding Taiwan Strait stability will also be important barometers of global concern and support.

Strategic recommendations:
Taiwan should prioritize accelerating its indigenous defense capabilities, particularly in asymmetric warfare assets like drones and advanced missile systems, while continuing to diversify its defense procurement. Strengthening national cybersecurity defenses, including critical infrastructure protection, public awareness campaigns against phishing, and rapid incident response mechanisms, is paramount given the surge in AI-assisted attacks. Enhancing international cooperation on intelligence sharing and cyber threat attribution with partners like the US, EU, and other G7 nations will be vital. Diplomatically, Taiwan should continue to highlight China's "gray zone" tactics to the international community, reinforcing the need for collective security and stability in the Indo-Pacific.
