On April 5, he transmitted a spoofed high-priority 'General Alarm' signal that triggered emergency braking on four trains, halting them for 48 minutes. The TETRA system had been in use for 19 years without rotating its parameters, allowing the attacker to bypass seven verification layers. An accomplice provided critical network parameters. Police traced the attack via CCTV and network logs, seizing 11 radios, an SDR, and a laptop. Lin now faces up to 10 years in prison under Taiwan's Criminal Law, while his lawyer claims the signal transmission was accidental. ## Full article daily.dev links to this article rather than hosting it.
