Introduction
Free DecryptAds scans the ads.txt, app-ads.txt, buyers.json and sellers.json files published by websites and applications, making advertising partners and data brokers visible.
Developments
The service aims to correlate this information to find the source of malicious ads, identify risky advertising networks and detect privacy threats.
DecryptAds’ review of espn.com identified 143 advertising partners and 19 registered data broker domains.
Details
It was reported that nearly half of these brokers collect location data from visitors who do not use ad blockers, while three brokers disclosed that they collect device fingerprints and sensitive personal information.
