The Side-Channel-Attacks Edition Wednesday, January 29, 2025

Apple Chips Can Be Hacked To Leak Secrets From Gmail, iCloud, And More, by Dan Goodin, Ars Technica

Apple-designed chips powering Macs, iPhones, and iPads contain two newly discovered vulnerabilities that leak credit card information, locations, and other sensitive data from the Chrome and Safari browsers as they visit sites such as iCloud Calendar, Google Maps, and Proton Mail.

The vulnerabilities, affecting the CPUs in later generations of Apple A- and M-series chip sets, open them to side channel attacks, a class of exploit that infers secrets by measuring manifestations such as timing, sound, and power consumption. Both side channels are the result of the chips’ use of speculative execution, a performance optimization that improves speed by predicting the control flow the CPUs should take and following that path, rather than the instruction order in the program.

[...]

The researchers published a list of mitigations they believe will address the vulnerabilities allowing both the FLOP and SLAP attacks. They said that Apple officials have indicated privately to them that they plan to release patches. In an email, an Apple representative declined to say if any such plans exist.

On The Undesign Of Apple Intelligence Features, by Nick Heer, Pixel Envy

Writing Tools, in particular, can and should be better. I write a little on my iPhone, but I write a lot on my Mac — not just posts here, but also emails, messages, and social media posts. A more advanced spelling and grammar checker that has at least some contextual awareness sounds very appealing to me. This is a letdown, and because of so many basic reasons. I do not need Apple Intelligence to be the apex of current technology. What I do expect, at the very least, is that it is user-friendly and feels at home on Apple’s own platforms. It needs work.

iOS 18.3 Enables Apple Intelligence By Default, by Benjamin Mayo

To be more sensitive about the public mood, I think they probably should have kept notification summaries as an opt-in feature, even if Apple Intelligence in general is turned on by default now. That’s the only real critique of this I can field.
