Google posted a security blog article today about Google ad injectors and how they are bad for advertisers, bad for publishers, and even worse for the users who are infected by them. As part of this report, Google disclosed that they have been conducting a study with researchers at University of California Berkeley and will be publishing a report on May 1st. As sample, they relased some information based on a sample of 100 million pageviews from users with Chrome, Internet Explorer, and FireFox:
- Ad injectors were detected on all operating systems (Mac and Windows), and web browsers (Chrome, Firefox, IE) that were included in our test.
- More than 5% of people visiting Google sites have at least one ad injector installed. Within that group, half have at least two injectors installed and nearly one-third have at least four installed.
- Thirty-four percent of Chrome extensions injecting ads were classified as outright malware.
- Researchers found 192 deceptive Chrome extensions that affected 14 million users; these have since been disabled. Google now incorporates the techniques researchers used to catch these extensions to scan all new and updated extensions.
