An article by The Guardian’s Glenn Greenwald on XKEYSCORE actually gathered the browsing habits of everyone who clicked and wasn’t protected (by private, encrypted, and/or proxy browsing),
reports Bob Cesca of the Daily Banter.
Using a free web application called Ghostery — which tells the user about embedded trackers — Cesca found that The Guardian embedded 27 tracking bugs inside Greenwald’s article.
The bugs track browsing metadata, a lot like what Greenwald exposed on June 6 with his article on the National Security Agency and Verizon.
Ostensibly, private companies track browsing metadata on the web in order to help advertise and market products to users online.
