Troops’ phones gave away location data to foreign adversaries
Lawmakers say foreign adversaries used commercial geolocation data to track U.S. troops, and the Pentagon has not moved fast enough to stop it.
Intelligence analysis by GPT-5.4 Mini
The Pentagon has acknowledged that adversaries have used commercially sourced location data to target or surveil U.S. personnel in the Middle East. A bipartisan group of lawmakers is now pressing the Defense Department to tighten smartphone controls, after years of warnings and weak enforcement.
Soldiers carry phones, and those phones can quietly share clues about where they are. Bad actors can buy that clue-data from companies that collect it for ads, then use it to follow troops.
Think of it like leaving tiny breadcrumbs on a path. One breadcrumb is harmless, but a whole trail shows where someone goes and when. That can be dangerous in a war zone.
The article says lawmakers want the Pentagon to lock down phones better. The worry is simple: if the phones keep telling on people, enemies can keep finding them.
Analysis
What happened
Lawmakers led by Sen. Ron Wyden and Rep. Pat Harrigan sent a letter to DoD CIO Kirsten Davies after getting responses from the Pentagon that appear to confirm a long-running risk: foreign adversaries have used commercial geolocation data to target or surveil U.S. personnel in war zones.
How the data leaks
The article says the data ultimately comes from smartphone advertising profiles and related device data sold through commercial brokers. The DoD response indicates that troops are allowed to use personal devices in operational areas, and that there is no policy requiring service members to turn off geolocation features in active war zones. The department says CENTCOM guidance tells personnel to disable geolocation when not needed and review privacy settings, but that guidance does not fully eliminate the risk.
Pentagon controls are incomplete
The DoD also says its own managed phones disable personalized advertising through group policy, but do not disable ad-targeting information entirely, and users can still edit some settings. The department says it is migrating to a new mobile device management system that should let it disable location services completely on government-issued devices, but the article notes it is unclear whether that migration is finished.
Why lawmakers are escalating
Wyden’s office says the public confirmation was delayed because of release restrictions. The letter argues the problem is not new: contractors reportedly warned military leadership as far back as 2016 that smartphones owned by service members could be tracked. The article frames the issue as one the Pentagon has known about for more than a decade, yet has not fixed decisively enough.
The story also notes that the Army is moving toward a BYOD model, which may make enforcement harder if personal phones remain in use. CENTCOM says it has strengthened geolocation controls, but the article says compliance across the force is still unclear.
Key points
- Lawmakers say adversaries used commercial location data to track U.S. troops in the Middle East.
- The DoD response says troops can use personal phones in operational areas and geolocation is not fully shut off.
- Managed DoD phones disable personalized ads, but not all ad-targeting data or location-related settings.
- The Pentagon says it is migrating to a new mobile device management system with stronger controls.
- The article says military leaders were warned about the risk as far back as 2016.
