Taiwan high‑speed rail system, one of the most important pieces of national infrastructure, was thrown into chaos during the Qingming Festival holiday when several trains suddenly came to an unexpected halt. Experts initially investigated a technical glitch but soon discovered the incident was caused by a cyber intrusion carried out by a 23-year-old university student.
“The Ministry of Transportation and Communications yesterday pledged to submit a report on ways to harden the communication security of railway systems after a university student hacked into Taiwan High Speed Rail Corp’s (THSRC) radio communications system and disrupted operations of four high-speed rail trains last month.” reported the Taipei Times. “Investigation by the police and prosecutors found that the university student and radio enthusiast, surnamed Lin (林), first used a software-defined radio (SDR) filter to analyze THSRC signals, downloaded the data to a computer, cracked the parameters and then programmed the codes into his radio devices.”
