## CBP Exploits Online Ad Ecosystem for Mass Location Tracking
U.S. Customs and Border Protection (CBP) has been covertly utilizing the online advertising ecosystem to track the movements of individuals. This operation involves purchasing commercially available location data harvested from smartphone apps, bypassing the need for traditional warrants. The data, often collected through software development kits (SDKs) embedded in mobile applications, provides precise, timestamped location information. CBP has used this data to monitor people's movements near the U.S. border and, reportedly, far into the interior of the country. This practice represents a significant expansion of government surveillance capabilities, leveraging the pervasive data collection infrastructure of the digital advertising industry. It raises profound legal and privacy concerns, as it allows for the tracking of millions of Americans and visitors without their knowledge or consent, effectively creating a warrantless mass surveillance system built on commercial data brokers.
