Security researchers at Google have found substantial privacy risks associated with Apple’s Safari anti-tracking protections…
Apple introduced its anti-tracking protections for its Safari browser back in 2017. At the time, advertisers and publishers were among the most concerned because it could have hurt their businesses. Now, new information unearthed by Google shows users of the service have even more reason to worry.
Google Security Researchers Uncover Serious Privacy Risks in Apple Safari’s Anti-Tracking Protections
Security researchers with Google have identified flaws in Safari’s anti-tracking protections that pose privacy risks.
The technology, called Intelligent Tracking Prevention, employs the use of machine learning to classify websites permitted to use browser cookies or scripts that are hosted on third-party domains to track users around the web.
However, the work of those anti-tracking protections actually come with unintended consequences. Namely, the ability to compile a list of recently visited sites, creating a persistent fingerprint that can follow people around the internet, leaking search results, as well as compelling unpermitted domains into using third-party scripts and/or cookies.
The researchers at Google made Apple aware of these vulnerabilities and say that the browser team has already fixed “a number of the issues” with release 13.0.4 for Safari and iOS 13.3.
