Apple unveiled iOS 27 and iPadOS 27, highlighting performance gains such as up to 30 percent faster app launches and up to 80 percent faster AirDrop transfers. It also touted quicker uploads to device libraries, up to fivefold faster file transfers with external storage, and improved switching between Wi-Fi and cellular networks, including on iPhone 11. At the same time, Apple tightened device support, dropping several older iPads and limiting watchOS 27 to newer Apple Watch models.

A newly disclosed web tracking technique can analyse SSD activity inside a browser to infer other websites a user is viewing and even apps running elsewhere. Researchers presented a contention-based side-channel method called Frost that repeatedly accesses large files in the browser’s Origin Private File System and measures tiny SSD I/O latency differences. They said the data can be analysed with a pre-trained convolutional neural network model. The method faces constraints, including the need for very large files and storage placement on the same SSD.
