DECRYPTADS is a new free service designed to enhance transparency in adtech by scraping publicly available ad data, helping users understand who tracks them online. It processes files such as ads.txt, app-ads.txt, and buyers.json/sellers.json to reveal partners involved in ad placements or data collection. Chief Research Officer Zach Edwards highlights the importance of cross-referencing this data to track malicious ads and identify threats.
DecryptAds flags high-risk ad partners based in countries like China and Russia, stressing issues related to supply chain integrity and malvertising, particularly prevalent on low-quality AI-generated sites. The service also features a legal dossier lookup for domain ownership insight and addresses how ad networks may quietly remove suspicious partners, creating accountability gaps. Users can mitigate tracking by using ad blockers and being cautious with mobile apps that often collect extensive data.
