Taiwan Student Accused of Spoofing Rail TETRA Alarm That Halted Four Trains
Summary
A Taiwanese student was arrested after authorities said a forged TETRA “General Alarm” halted four high-speed rail trains for 48 minutes. The suspect’s lawyer says the transmission was accidental.
Key points
- Authorities say the student used software-defined radio equipment and handheld radios to transmit a forged TETRA “General Alarm,” triggering emergency braking.
- Four Taiwan High Speed Rail trains were halted for 48 minutes on April 5.
- Reports say the student intercepted and decoded TETRA parameters that apparently had not been rotated in 19 years, bypassing seven verification layers.
- Police say an alleged accomplice supplied some critical rail-system parameters.
- Police traced the suspect using CCTV footage and TETRA logs, then seized 11 handheld radios, an SDR, and a laptop.
- The student faces charges under Article 184 and was released on bail. His lawyer says the transmission was accidental; authorities reportedly find that claim unconvincing.
