Who’s Tracking You? Use This New Service to Find Out

DecryptAds, a new free service launched by security researchers, aggregates publicly available adtech configuration files (ads.txt, app-ads.txt, and sellers.json) to reveal which companies track users and serve ads across websites and mobile applications. The tool identifies concerning patterns including advertising partners based in geopolitical risk areas like Russia and China, potential conflicts of interest where firms act as both publisher and reseller, and connections to AI-generated content farms that lack protective measures against malicious ads. DecryptAds also features a quiet removals feed that tracks when ad networks silently delist suspicious partners without public disclosure.

Why it matters: Security practitioners and organizations should use DecryptAds to audit their own web properties and identify third-party adtech risks, geopolitical exposures, and potential malvertising vectors; defenders should understand that malicious ads increasingly target lower-quality AI content farms rather than major sites, and that supply chain visibility in adtech remains fragmented because ad networks do not broadly share structured data needed to trace malware delivery.
