What happened
The United States military has disabled ad trackers on troop smartphones due to concerns that Iranian agents could use them to inflict harm. This decision highlights the potential dangers of ad tracking, which can be used to exploit individuals financially and compromise their privacy.
Ad trackers are small pieces of software code that monitor users' activities, such as clicks and purchases, and track their location and browsing habits. This information is then used to serve personalized ads, but it can also be used by malicious actors to exploit individuals.
There have been several instances of ad tracking being used to exploit individuals, including a case in 2024 where tens of thousands of Americans were tricked into signing up for alternative health insurance plans after clicking on social media ads. In another case, hospitals were found to be using tracking pixels on their websites and patient portals, which routed sensitive personal health data to social media servers.
The system used for ad tracking can also be used to track individuals' physical locations, with commercial tools available that can map mobile advertising IDs onto real-world coordinates. This has raised concerns about the potential for individuals to be tracked without their consent or knowledge.
To protect their privacy, individuals can take steps to disable ad tracking on their smartphones. On iPhones, this can be done by opening Settings, going to Privacy & Security, selecting Tracking, and toggling off Allow Apps to Request to Track. On Android devices, users can open Settings, select Privacy, tap Ads, and choose Delete advertising ID.
