JapanJapan's national emergency alert system, known as J-Alert, is vulnerable to fake data due to a lack of encryption and source verification capabilities, according to a cybersecurity expert. The system transmits early warnings about natural disasters and missile threats via satellites to local governments, which then relay alerts to the public through various channels. Yudai Kirishiki of Unknown Technologies Inc identified flaws in the system after analyzing a used receiver sold on the secondhand market, revealing that the system cannot authenticate data sources or detect fake alerts sent from elevated positions, such as drones. While the government acknowledges the issue and claims to be addressing it, officials did not provide specific details, citing security concerns. The sale of retired equipment was described as 'regrettable,' despite prior guidelines for proper disposal.
