WTF?! For years, military technologists and outside researchers have warned that the commercial data economy could put US troops in the crosshairs. Those warnings are no longer hypothetical. US Central Command now says adversaries are exploiting commercial location data to track American personnel in active war zones, confirming that the same infrastructure that powers targeted advertising is being used against deployed forces.

In a recently disclosed letter, Centcom said it had received "multiple threat reports concerning adversary exploitation of commercial location data to target or surveil US personnel in theater." It is also the first time the military has formally acknowledged that data broker feeds are being used against US forces in the Middle East.

This acknowledgment comes after nearly a decade of technical alerts, internal demonstrations, and academic work, all pointing to the same problem: off-the-shelf tracking tools can reveal where US service members live, work, train, and even move through sensitive locations.

The core technology is basic adtech rather than anything resembling traditional espionage. Mobile apps collect geolocation and advertising IDs, third-party trackers follow devices across sites and services, and brokers package that data into products they sell to customers.
