UM…: US troops can still be tracked by purchased location data, and Congress wants to know why.

US Senator Ron Wyden (D-OR) and Rep. Pat Harrigan (R-NC) on Friday asked for an investigation by the Defense Department Inspector General into policies that have only partially stanched the flow of location data that allows military personnel to be tracked and targeted.

In May, Wyden, Harrigan, and a bipartisan group of 12 other members of Congress released details about how commercially purchased location data – often captured by mobile apps and advertising SDKs – can be used to identify where US military personnel gather and to target those locations. They noted that the DoD has been aware of this threat since at least 2016.

The lawmakers urged Defense Department CIO Kirsten A. Davies to take steps to mitigate this risk, including turning off advertising identifiers on DoD smartphones and issuing a policy requiring the disabling of advertising identifiers on all personal devices brought into DoD facilities or overseas.

This seems like no-brainer stuff, and the DOD has sat on it for a decade?
