Apple has confirmed that governments are using push notifications to surveil users, with foreign officials demanding data from tech giants to track smartphones. The company stated that it was previously prohibited from sharing this information, but is now updating its transparency reporting to detail these kinds of requests. The surveillance method involves tracking metadata related to push notifications, which can be used to tie anonymous users of messaging apps to specific Apple or Google accounts. Apple advises developers to not include sensitive data in notifications and to encrypt any data before adding it to a notification payload.
