Chrome extensions with 1.4M installed secretly track visits and inject code

Behind the scenes, the company’s researchers said, the extensions kept a playlist of every site a user visited and took additional actions when users reached specific sites.

The plugins send the name of each visited site to the dedicated developer site d.langhort.com, along with a unique ID, country, city, and zip code for the visiting device. If the visited site matches a list of e-commerce sites, the developer domain directs extensions to include JavaScript on the visited page. The code modified the site’s cookies so that the extension authors receive affiliate payments for any items purchased.

To help keep activity confidential, some extensions are programmed to wait 15 days after installation before beginning to collect data and enter code. The selected extensions from McAfee are:
