A researcher claims telecom company AT&T tampers with its free Wi-Fi hotspots to inject ads on peoples' devices.
The ad content apparently comes from third-party providers and is facilitated by RaGaPa. Mayer documented ads showing up on Stanford's website, the homepage of The Wall Street Journal and federal government websites.
Connections made over HTTPS will not display the ads, the researcher wrote.UPDATE: AT&T responded to SCMagazine.com's request for comment. The company said it ran "advertising program" trials at both Washington Dulles International Airport, where Mayer conducted his research, and at Ronald Reagan Washington National Airport. “The trial was part of an ongoing effort to explore alternate ways to deliver a free Wi-Fi service that is safe, secure and fast,"the statement says.
