Taiwan Security Research Breach Incident Score: Analysis & Impact (TAINAT1767621958)

In this Rankiteo incident briefing, we review the Taiwan Security Research breach identified under incident ID TAINAT1767621958.

The analysis begins with a detailed overview of Taiwan Security Research's information like the linkedin page: https://www.linkedin.com/company/taiwan-security-research, the number of followers: 193, the industry type: Research Services and the number of employees: 2 employees

After the initial compromise, the video explains how Rankiteo's incident engine converts technical details into a normalized incident score. The incident score before the incident was 749 and after the incident was 731 with a difference of -18 which is could be a good indicator of the severity and impact of the incident.

In the next step of the video, we will analyze in more details the incident and the impact it had on Taiwan Security Research and their customers.

Taiwanese Government recently reported "Unprecedented Wave of Chinese Cyberattacks on Taiwan's Critical Infrastructure (2025)", a noteworthy cybersecurity incident.

In 2025, Taiwan faced an unprecedented wave of Chinese cyberattacks targeting its critical infrastructure, with an average of 2.63 million daily incidents recorded.

The disruption is felt across the environment, affecting Energy services, Hospitals and Emergency rescue systems, and exposing Data interception and theft from telecommunications networks.

In response, teams activated the incident response plan, moved swiftly to contain the threat with measures like Advanced threat detection, Improved incident response teams and Real-time monitoring, and began remediation that includes Infrastructure hardening and Rapid containment tactics, and stakeholders are being briefed through Coordination between government agencies and private-sector cybersecurity experts.

The case underscores how Ongoing, teams are taking away lessons such as The need for stronger domestic cybersecurity measures, international collaboration, and resilience building across public and private sectors to counter state-backed cyber threats, and recommending next steps like Enhance threat intelligence sharing, Develop global norms for state behavior in cyberspace and Build cooperative defense mechanisms, with advisories going out to stakeholders covering Taiwanese officials emphasize the strategic dimension of these cyber campaigns and the need for coordinated defense efforts.

Finally, we try to match the incident with the MITRE ATT&CK framework to see if there is any correlation between the incident and the MITRE ATT&CK framework.

The MITRE ATT&CK framework is a knowledge base of techniques and sub-techniques that are used to describe the tactics and procedures of cyber adversaries. It is a powerful tool for understanding the threat landscape and for developing effective defense strategies.

Rankiteo's analysis has identified several MITRE ATT&CK tactics and techniques associated with this incident, each with varying levels of confidence based on available evidence. Under the Initial Access tactic, the analysis identified Exploit Public-Facing Application (T1190) with moderate to high confidence (70%), with evidence including dDoS attacks to overwhelm systems, and probing attempts on critical infrastructure and External Remote Services (T1133) with moderate confidence (60%), supported by evidence indicating network Intrusion targeting energy grids and telecom networks. Under the Impact tactic, the analysis identified Network Denial of Service (T1498) with high confidence (90%), with evidence including dDoS attacks (2.63M daily incidents), and overwhelm systems in critical sectors and Data Manipulation: Transmitted Data Manipulation (T1565.002) with moderate to high confidence (80%), supported by evidence indicating man-in-the-middle attacks to intercept data. Under the Collection tactic, the analysis identified Data from Local System (T1005) with moderate to high confidence (70%), supported by evidence indicating theft of proprietary semiconductor technologies and Network Sniffing (T1040) with moderate to high confidence (80%), supported by evidence indicating data interception from telecommunications networks. Under the Exfiltration tactic, the analysis identified Exfiltration Over C2 Channel (T1041) with moderate to high confidence (80%), supported by evidence indicating data exfiltration confirmed in incident details. Under the Command and Control tactic, the analysis identified Application Layer Protocol (T1071) with moderate confidence (60%), supported by evidence indicating highly coordinated attacks aligned with military exercises. Under the Reconnaissance tactic, the analysis identified Active Scanning (T1595) with moderate to high confidence (70%), supported by evidence indicating probing attempts on energy grids and emergency systems. These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
