Google enables marketers to target people with serious illnesses and crushing debt—against its policies—as well as the makers of classified defense technology, a WIRED investigation has found.

Display & Video 360 (DV360), one of the dominant marketing platforms offered by Google, 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.

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.”

The data—first obtained by the Irish Council for Civil Liberties (ICCL), reveals segments targeting hundreds of millions of device users based exclusively on health conditions, from chronic pain and menopause to, among others, fibromyalgia, psoriasis, arthritis, high cholesterol, and hypertension.

Despite this, many data segments targeted households and businesses facing financial hardship, helping advertisers identify people who are in the process of bankruptcy or burdened by long-term debt.

Segments accessible through DV360 that target Americans with asthma contain at least hundreds of millions of mobile IDs—among them, a list simply titled, “People who have asthma.”

A vast number of devices and user profiles are spread out across lists that target users determined likely to need specific medications, including some controlled substances, such as Ambien.
