iLeakage Attack: Theft of Sensitive Data from Apple’s Safari Browser
A team of researchers comprising Georgia Tech’s cybersecurity professors, Daniel Genkin and Jason Kim, University of Michigan’s Stephan van Schaik, and Ruhr University Bochum’s Yuval Yarom have published a research paper explaining a vulnerability they discovered in Apple devices that affects Macs and iPhones.
Researchers explained in the paper titled “iLeakage: Browser-based Timerless Speculative Execution Attacks on Apple Devices,” that the vulnerability, dubbed iLeakage, has been affecting Macs and iPhones since 2020. The attack mainly affects those devices that were built with Apple’s Arm-based A-series and M-series chips.
Researchers devised an attack that forced Apple’s Safari browser to divulge passwords, Gmail content, and other sensitive data by exploiting a side channel vulnerability in the CPUs.
