Scientists have devised a new tracking method through the browser — websites can spy based on SSD activity
Summary
Researchers describe a new browser-based tracking method called FROST that can fingerprint users by measuring SSD activity through OPFS and JavaScript. The technique works without special hardware access and can operate across major desktop operating systems. The article highlights that the attack can be used through ordinary websites, which makes it difficult for users to notice or block. It also shows how browser and storage-layer behavior can become a privacy risk for software environments.
