Google Ad-Tech Users Can Target National Security ‘Decision Makers’ and People With Chronic Diseases

A WIRED investigation into the inner workings of Google’s advertising ecosystem reveals that a wealth of sensitive information on Americans is being openly served up to some of the world’s largest brands despite the company’s own rules against it. Display & Video 360, one of the dominant marketing platforms offered by the search giant, is offering companies globally the option of targeting devices in the United States based on lists of internet users believed to suffer from chronic illnesses and financial distress, among other categories of personal data that are ostensibly banned under Google’s public policies. Other lists of American users accessible for a price across the platform raise serious national security concerns, experts say, as they reveal data brokers striving to isolate millions of mobile devices carried by government workers—from US judges and military service members to executive agency staff and employees on Capitol Hill. First reviewed by WIRED, an internal spreadsheet obtained from a US-based data broker shows the DV360 platform currently hosting hundreds if not thousands of restricted or otherwise sensitive “audience segments,” each containing a large tranche of data that points to countless mobile devices and online profiles of people in the US. “Our policies do not permit audience segments to be used based on sensitive information like employment, health conditions, financial status, etc.” Despite this, numerous segments contained in the data are clearly targeted at households and businesses based purely on data suggesting they’re experiencing financial hardship—aiming, for instance, to help advertisers identify people who are in the process of bankruptcy or burdened by long-term debt.
