Apple publishes safety guide addressing AirTag fears

Apple tries to address AirTag unwanted tracking issues in updated safety document.

Both AirTag and the Find My network are designed with privacy at their core. AirTag and Find My network accessories have unique Bluetooth identifiers that change frequently. To discourage unwanted tracking, Find My notifies you if an unknown AirTag or other Find My accessory is seen moving with you over time by sending you the message, “Item Detected Near You.” (This feature is available on iPhone, iPad, or iPod touch running iOS 14.5 or iPadOS 14.5 or later). If you see this message on your device, an AirTag or other Find My accessory that has been separated from the person who registered it is traveling with you, and the owner might be able to see its location. It’s possible that the AirTag might be attached to an item you are borrowing.

Safari bug leaks user information, allowing user tracking

Safari 15 is exposing IndexedDB data to opened sites and in tabs and recently opened.

Sites cannot read contents of IndexedDB, however, names of databases are accessible to all sites. Google keeps user ID as a part of database name allowing cross-site tracking.

Use alternate browsers, until fix is released

Even Private Mode is vulnerable, no workarounds are available at the time.
iOS alternate browsers are also vulnerable, and Private Mode does not fully protect from tracking.

Users should use alternate browsers on macOS and wait for Apple's fix.

Apple publishes ‘Tracker Detect’ app to prevent Android users from being tracked by AirTags

Apple released 'Tracker Detect' application for Android. This apps will warn users if it sees unwanted AirTag traveling with the user.

App detects AirTags that are separated from their owners and displays those. This minimizes risks of false alarms.

It seems, however, that currently app does not detect AirTags in background and user needs to explicitly launch an app and perform scan manually.
