The Beijing Winter Olympics app that all Games attendees must use contains security weaknesses that leave users exposed to data breaches, analysts say.
The My2022 app will be used by athletes, audience members and media for daily Covid monitoring.
The app will also offer voice chats, file transfers and Olympic news.
Questions about the app come amid a rise in warnings about visitors’ tech security ahead of the Games, which begin on 4 February.
People attending the Beijing Olympics should bring burner phones and create email accounts for their time in China, cyber security firm Internet 2.0 said on Tuesday.
