In this Rankiteo incident briefing, we review the Taiwan High Speed Rail Corporation. breach identified under incident ID THS1778070612.
The analysis begins with a detailed overview of Taiwan High Speed Rail Corporation.'s information like the linkedin page: https://www.linkedin.com/company/thsrc, the number of followers: 2550, the industry type: Truck Transportation and the number of employees: 679 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 765 and after the incident was 752 with a difference of -13 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 High Speed Rail Corporation. and their customers.
On 06 April 2024, Taiwan High Speed Rail (THSR) disclosed Radio Signal Spoofing issues under the banner "Taiwan High Speed Rail Radio Signal Spoofing Attack".
During Taiwan’s Qingming Festival holiday, the Taiwan High Speed Rail (THSR) suffered a targeted cyberattack that forced three trains into emergency stops, causing a 48-minute disruption.
The disruption is felt across the environment, affecting Taiwan High Speed Rail (THSR) operational technology and communication systems.
In response, moved swiftly to contain the threat with measures like Investigation and seizure of electronic devices and broadcasting hardware.
The case underscores how Ongoing (suspect arrested, released on bail), with advisories going out to stakeholders covering Taoyuan District Prosecutors’ Office warning on future attacks on critical infrastructure.
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.
