The Pentagon Knew Enemies Could Track Troops’ Phones for Years. Now They Are
Pentagon warnings about commercial phone-location data went unheeded for years, and a newly disclosed letter says adversaries are now using it to target US personnel.
Intelligence analysis by GPT-5.4 Mini
WIRED traces a decade of warnings that data brokers and ad tech could expose troops' locations, then shows the Pentagon now acknowledging adversaries are using that commercial data to target or surveil US personnel in the Middle East.
The story is about soldiers' phones leaking clues about where they are. Those clues can be sold like stickers in a market, and bad actors can buy them.
For years, people in and around the Pentagon said this was dangerous. The article says the warnings were mostly ignored, even though some fixes were cheap and simple.
Now the Pentagon is saying enemies may already be using that phone data to watch or target US troops. It is like leaving footprints in wet cement and pretending nobody will notice them.
Analysis
What the story says
WIRED reports that the Pentagon and other US agencies were warned for years that commercially available location data could expose service members. The article says those warnings came from contractors, analysts, intelligence agencies, lawmakers, and Army researchers, but most of the recommended protections were not adopted.
The new acknowledgment
A newly disclosed letter to the Pentagon says US Central Command has received multiple reports that adversaries are using commercial location data to target or surveil US personnel in theater. That matters because it is the first official confirmation, in the story's framing, that the data-broker economy is being used against American forces in the Middle East.
How the risk showed up
The article walks through several examples. A 2016 briefing reportedly showed how bought location data could track phones from major US bases into Syria. In 2021, the Defense Intelligence Agency said it used commercially purchased phone location data without a warrant. In 2023, Duke researchers working with a West Point grant found brokers selling data on military personnel, including home addresses, health conditions, and financial details, sometimes for pennies per record.
Why the fix has been slow
WIRED says the Pentagon has treated some of this as an individual discipline problem, telling troops to follow operational-security rules. But Army Cyber Institute research found commercial trackers on a large share of commonly visited domains and said fixes would require minimal funding or resources. The lawmakers behind the new letter are now asking for basic protections such as disabling advertising IDs on military phones, removing Chrome from government devices, and enrolling troops in broker opt-out systems.
Key points
- The article says the Pentagon was warned for years that commercial location data could expose troops and bases.
- US Central Command has now confirmed receiving reports of adversaries using that data to target or surveil US personnel in theater.
- WIRED says researchers and lawmakers repeatedly found the data was easy to buy and often poorly checked by brokers.
- Army research found commercial trackers on many commonly visited domains and described some fixes as low-cost.
- The piece frames the problem as both a security failure and a policy failure.
