New Browser Attack Allows Tracking Users Online With JavaScript Disabled Researchers have discovered a new side-channel that they say can be reliably exploited to leak information from web browsers that could then be leveraged to track users even when JavaScript is completely disabled. This is a side-channel attack which doesn t require any JavaScript to run, the researchers said. This means script blockers cannot stop it. The attacks work even if you strip out all of the fun parts of the web browsing experience. This makes it very difficult to prevent without modifying deep parts of the operating system. In avoiding JavaScript, the side-channel attacks are also architecturally agnostic, resulting in microarchitectural website fingerprinting attacks that work across hardware platforms, including Intel Core, AMD Ryzen, Samsung Exynos 2100, and Apple M1 CPUs making it the first known side-channel attack on the iPhone maker s new ARM-based chipsets. ....
Security researchers have discovered what appears to be the first browser side-channel attack that s Javascript-free, and Apple M1 chips may be more vulnerable to it. The attack is built entirely from HTML and CSS, and is described as architecturally agnostic. The researchers say they ve found it to work across Intel, Samsung, AMD, and Apple Silicon CPUs, according to The 8-Bit. According to a research paper published by Cornell University, the researchers say they started with the goal of exploring how effective disabling or restricting JavaScript could be in mitigating attacks. Through the course of their research, the team was able to create a new side-channel proof of concept built entirely in CSS and HTML, which could open the door to microarchitectural website fingerprinting attacks. It works even if script execution is completely blocked on a browser, they said. ....
