AT&T Hotspots: Now With Advertising Injection

Jonathan Mayer, investigating how AT&T’s “free” Wi-Fi at Dulles International Airport injects ads into all non-HTTPS web pages:

AT&T has an (understandable) incentive to seek consumer-side income from its free wifi service, but this model of advertising injection is particularly unsavory. Among other drawbacks: It exposes much of the user’s browsing activity to an undisclosed and untrusted business. It clutters the user’s web browsing experience. It tarnishes carefully crafted online brands and content, especially because the ads are not clearly marked as part of the hotspot service. And it introduces security and breakage risks, since website developers generally don’t plan for extra scripts and layout elements.

It’s dishonest and dangerous.
