Google researchers have exposed details of multiple security flaws in Safari web browser that allowed user's browsing behavior to be tracked.

According to a report : The flaws which were found in an anti-tracking feature known as Intelligent Tracking Prevention, were first disclosed by Google to Apple in August last year. In a published paper, researchers in Google's cloud team have identified five different types of attacks that could have resulted from the vulnerabilities, allowing third parties to obtain "sensitive private information about the user's browsing habits."

Apple rolled out Intelligent Tracking Prevention in 2017, with the specific aim of protecting Safari browser users from being tracked around the web by advertisers and other third-party cookies.
