Ars Technica, reporting on the hack of analytics firm PageFair:
One of those sites were the Economist, as is widely reported. Third party scripts and services is a forgotten security hazard today. Probably more so than ever, since PageFair is an anti-content blocker. From their about page:
We started PageFair because we personally experienced the damage adblocking can do to a website. While we recognize that visitors need to defend themselves from distracting, intrusive, inappropriate, disingenuous or malicious advertising, the rise of adblocking is now leading to the death of quality free websites.
Add PageFair to a service you should block, for your own safety.
