Fake data may activate Japan's emergency alert: expert
TOKYO (Kyodo) -- Japan's nationwide emergency alert system lacks the capability to encrypt data transmitted via satellites and verify the source, maki
Japan's nationwide emergency alert system, known as J-Alert, has a vulnerability that could allow hackers to transmit fake data and trigger false warnings, according to cybersecurity expert Yudai Kirishiki. The flaw lies in the system's inability to encrypt data transmitted via satellites or verify the source of the information.
This issue was confirmed through analysis using a receiver that later appeared on the secondhand market. Kirishiki's findings suggest that a third party could exploit this weakness to send false alerts, potentially disrupting people's lives. Despite this, the government is reportedly working to ensure the system's stability and will respond appropriately to the matter.
The issue arose because cyberattacks on the satellite communications system were not initially considered a significant threat when J-Alert was first implemented in 2007.
