A Review of Major Cybersecurity Incidents in Taiwan in 2025: Healthcare, Finance, and Manufacturing All Hit

In 2025, Taiwan’s digital landscape has moved beyond an era of passive defense. From confidential data leaks on manufacturing production lines and patient data risks within healthcare systems, to service disruptions at financial institutions and government agencies becoming prime targets for cyberattacks, cybersecurity incidents have clearly crossed industry boundaries and evolved into a shared challenge for all organizations. Beyond the increasing diversity and sophistication of attack methods, human-related data leaks continue to occur. Questions around excessive data access privileges and whether incident response mechanisms are sufficient when breaches happen have become critical issues that enterprises must seriously reassess. Today, the question is no longer whether a cybersecurity incident will occur, but when it will happen and whether an organization is resilient enough to withstand it.

An Overview of Internal and External Cybersecurity Challenges Across Four Key Industries

  • Healthcare:In February 2025, a medical center in Taipei was hit by a CrazyHunter ransomware attack, causing more than 500 computers in its emergency department to crash. Medical staff were temporarily unable to access patient record systems, and the personal data of tens of millions of patients was exposed.
  • Finance:In February 2025, a claims officer at an insurance company took advantage of gaps in the internal claims approval system, impersonating a supervisor to authorize claims. This bypass of internal oversight enabled the fraudulent processing of numerous false claims, resulting in losses exceeding NT$20 million.
  • Education:In June 2025, a private university in central Taiwan was hit by a Nova ransomware attack, with the attackers claiming to have obtained 10 GB of data
  • Manufacturing:In August 2025, an internal employee at a major semiconductor company leaked confidential technology. The cybersecurity team, through routine monitoring, detected unusual network activity and discovered that the employee had remotely accessed the internal R&D system and transferred data using a mobile device.

Observing the incidents above, it is clear that cybersecurity risks are not limited to external attacks; internal accounts can also become sources of risk. At the core of the problem is the overtrust placed in data and identities. The points of intrusion vary—some involve leaked accounts, others exploit supply chain vulnerabilities, and some result from the abuse of internal privileges. However, what truly amplifies the damage is not merely unauthorized access, but that once inside, files can be freely accessed, laterally spread, and proliferate uncontrollably.

4 Core Data Issues Across Industries

Regardless of industry, as organizations continue to accumulate growing volumes of data—including large amounts of product-sensitive and personal information—enterprises are increasingly recognizing that data risks grow in parallel with their digital transformation initiatives and AI adoption. Data is no longer just an operational asset; it has become a primary target for attackers. Consequently, more and more organizations are investing in cybersecurity resources and re-evaluating their data governance and protection capabilities. Across industries, the data challenges faced by enterprises can be summarized into four core dimensions:
  1. Regulatory and Audit Requirements:From the Personal Data Protection Act and industry regulatory standards to internal and external audit mechanisms, organizations must clearly understand where data is stored, how it is accessed, and its usage trails. Only then can they ensure traceability and accountability when facing audits.
  2. Access Control Requirements:Beyond strict identity verification, organizations must dynamically adjust access rights based on an individual’s role, responsibilities, and context. This helps prevent over-privileging, which can become a potential source of internal data leaks and misuse.
  3. External Data Sharing:As supply chain collaborations, outsourced services, and cross-organization partnerships become routine, data increasingly flows beyond organizational boundaries. This significantly raises the risks of data leakage, misuse, and unrecoverable access rights. Ensuring that data remains effectively controlled during external exchanges, while maintaining business efficiency, has become a critical challenge for enterprises.
  4. High-Security Network Environment:In line with corporate cybersecurity policies, network architectures must incorporate layered defenses to prevent lateral movement from a single point of intrusion. Coupled with real-time monitoring and incident response mechanisms, this enables organizations to quickly detect and block threats at an early stage, minimizing impact on operations and data security.
However, in practice, many organizations find that even after investing significant resources in cybersecurity infrastructure and management policies, the implementation of the four core data issues still faces challenges. The key reason is that most protections remain centered on “network perimeters” and “user identities,”Once authentication is passed, files themselves often lack further control mechanisms, making it difficult to fully enforce regulatory requirements. Access controls tend to remain static, and external data exchanges lack visibility.

OmniStor Zero Trust File System

From Internal Risks to External Threats: Achieving Proactive Governance and Strengthened Defense

To strengthen zero-trust practices and enhance data security, ASUS Cloud has developed OmniStor, a Zero Trust file management system focused on ultimate data protection and regulatory compliance. Built on a zero-trust architecture to address all enterprise data management needs, OmniStor establishes a multi-layered data governance framework and supports multiple deployment models. From identity authentication to data protection, it encompasses all core elements of zero trust, offering a proactive, integrated, and secure enterprise file management solution to address internal data security concerns and external threats. OmniStor features the following four key highlights:

  1. Data Access and Activity Control: Enforcing Least Privilege and Zero Trust Architecture
  2. Encryption in Transit and at Rest with Identity Authentication: Establishing Secure File Exchange Mechanisms Across the Supply Chain
  3. Multi-Layered Secure Network Architecture: Supporting Integration with Security Software via API and ICAP
  4. Comprehensive File Audit Trails: Enable On-Demand Access Review and Rapid Investigation in Case of Incidents

As 2026 approaches and data risks continue to grow, ASUS Cloud is focusing on helping enterprises establish a “Responsible Data Layer” as its core direction. This approach ensures that enterprise data across industries remains controllable, traceable, and auditable in all application scenarios. Furthermore, when enterprises begin adopting AI, they can maintain strong data governance, ensuring that data sources and ownership can be verified, usage scope can be controlled, and actions can be tracked.
