For the current Olympics it has been pointed out that participants were required to install an event written and approved App on their phones to link to activities. But it has also been pointed to danger of security leaks, especially regarding the definition of private vs public vs group data. The event indicated that this data was in part to track pandemic transmission.

China's Olympics: Leave your tech at home
Last Tuesday, the US FBI warned that visitors to this year's Olympic Games being hosted in Beijing, China would be well advised to leave any fancy electronics at home. Grab an inexpensive “burner” phone that can be broken into pieces once you've returned to your local airport. In other words, the advice about traveling to China is similar to the traditional advice for attending the annual BlackHat and DefCon conferences in Las Vegas: Be afraid. Be very afraid.
The FBI didn’t mention any specific threats. But they didn't need to because it has become understood that “malicious cyber actors could use a broad range of cyber activities to disrupt these events.” There is just a tremendous amount of malicious cyber activity occurring during these events. Recall that the Tokyo Summer Olympics was a similar mess with athletes and attendees’ personal phones being targeted, the Games’ TV broadcasts being disrupted, and the personal data of volunteers and ticket purchasers for the Tokyo Olympics being leaked online. The Olympics are high profile and this makes everything happening there a target.
