The mandatory smartphone app that athletes will use to report health and travel data when they are in China for the Olympics next month has serious encryption flaws, according to a new report, raising security questions about the systems that Beijing plans to use to track Covid-19 outbreaks.
Portions of the app that will transmit coronavirus test results, travel information and other personal data failed to verify the signature used in encrypted transfers, or didn’t encrypt the data at all, according to the report by Citizen Lab, a University of Toronto cybersecurity watchdog. The group also found that the app includes a series of political terms marked for censorship in its code, though it does not appear to actively use the list to filter communications.
