TechCrunch reports that Apple has temporarily disabled the built-in Walkie-Talkie app on the Apple Watch because of an unspecified vulnerability that could “allow a person to listen to another customer’s iPhone without consent.” Although the app remains on your Apple Watch, it won’t be able to connect to other users. Presumably, Apple will release a software update to re-enable soon. Apple said that it’s not aware of the vulnerability being exploited in the wild.
Interestingly, Apple added that it was made aware of the vulnerability through the “Report a security or privacy vulnerability” page that it established after the Thompson family hit a bundle of red tape when it tried to tell Apple about the Group FaceTime eavesdropping bug (see “Apple Fixes Group FaceTime Bug; Promises to Improve Bug Reporting Process,” 1 February 2019). It appears Apple has made good on its promise to improve its bug reporting process.
