Cybersecurity experts at the Norwegian broadcasting corporation, NRK, are warning World Cup attendees to not carry their smartphones on their person at the event, India Times reports. Attendees will be required by host nation Qatar’s government to download two mobile applications called Ehteraz, a COVID-19 tracking app, and Hayya, the official app of the World Cup for attendees to download their tickets and utilize free public transportation while in Qatar. NRK researchers found Hayya “seeks access to share your personal information without almost any restrictions,” and Ehteraz has “several access requirements.”
