New SLAP & FLOP Attacks Expose Apple M-Series Chips to Speculative Execution Exploits

A team of security researchers from Georgia Institute of Technology and Ruhr University Bochum has demonstrated two new side-channel attacks targeting Apple silicon that could be exploited to leak sensitive information from web browsers like Safari and Google Chrome. The attacks have been codenam...

ShadyShader: Crashing Apple Devices with a Single Click

Introduction A while ago, we discovered an interesting vulnerability in the GPU’s drivers of iPhones, iPads, and macOS computers with M-series chips. Dubbed ShadyShader, this flaw allows a specially crafted shader program to overwhelm Apple’s GPU, causing repeated freezes that ultimately lead to ...

Hardware Vulnerability in Apple’s M-Series Chips

Its yet another hardware side-channel attack: The threat resides in the chips’ data memory-dependent prefetcher, a hardware optimization that predicts the memory addresses of data that running code is likely to access in the near future. By loading the contents into the CPU cache before it’s...
