Intel and AMD Trusted Enclaves, a Foundation For Network Security, Fall To Physical Attacks

2 months 3 weeks ago
Researchers have unveiled two new hardware-based attacks, Battering RAM and Wiretap, that break Intel SGX and AMD SEV-SNP trusted enclaves by exploiting deterministic encryption and physical interposers. Ars Technica reports: In the age of cloud computing, protections baked into chips from Intel, AMD, and others are essential for ensuring confidential data and sensitive operations can't be viewed or manipulated by attackers who manage to compromise servers running inside a data center. In many cases, these protections -- which work by storing certain data and processes inside encrypted enclaves known as TEEs (Trusted Execution Enclaves) -- are essential for safeguarding secrets stored in the cloud by the likes of Signal Messenger and WhatsApp. All major cloud providers recommend that customers use it. Intel calls its protection SGX, and AMD has named it SEV-SNP. Over the years, researchers have repeatedly broken the security and privacy promises that Intel and AMD have made about their respective protections. On Tuesday, researchers independently published two papers laying out separate attacks that further demonstrate the limitations of SGX and SEV-SNP. One attack, dubbed Battering RAM, defeats both protections and allows attackers to not only view encrypted data but also to actively manipulate it to introduce software backdoors or to corrupt data. A separate attack known as Wiretap is able to passively decrypt sensitive data protected by SGX and remain invisible at all times.

Apple Shelves Vision Headset Revamp to Prioritize Meta-Like AI Glasses

2 months 3 weeks ago
Apple has paused development of a cheaper, lighter Vision Pro headset to shift resources toward AI-powered smart glasses aimed at competing with Meta. Bloomberg's Mark Gurman reports: The company had been preparing a cheaper, lighter variant of its headset -- code-named N100 -- for release in 2027. But Apple announced internally last week that it's moving staff from that project to accelerate work on glasses, according to people with knowledge of the matter. The company is working on at least two types of smart glasses. The first one, dubbed N50, will pair with an iPhone and lack its own display. Apple aims to unveil this model as soon as next year, ahead of a release in 2027, said the people, who asked not to be identified discussing internal matters. Apple is also working on a version with a display -- something that could challenge the just-released Meta Ray-Ban Display. The Apple version had been planned for 2028, but the company is now looking to accelerate development, the people said. [...] Apple's glasses will rely heavily on voice interaction and artificial intelligence -- two areas where it hasn't always excelled. It was slow to introduce the Apple Intelligence platform and had to delay upgrades to its Siri voice assistant. The Apple glasses are expected to come in a variety of styles and run a new chip. They'll include speakers for music playback, cameras for media recording, and voice-control features that will work with a connected phone. Apple has also been exploring a suite of health-tracking capabilities for the device. The priority shift to glasses is just the latest change to the company's headset strategy following an underwhelming debut by the Vision Pro. The $3,499 product, which melds virtual and augmented reality, is seen as too heavy and expensive to be a mainstream hit. It's also short on both video content and apps. Apple executives have acknowledged the product's shortcomings in private, viewing it as an overengineered piece of technology.

AirPods Pro 3 Impossible To Repair, Earn Score of 0 In iFixit Teardown

2 months 3 weeks ago
An anonymous reader quotes a report from MacRumors: iFixit today disassembled the AirPods Pro 3, giving us a look at what's inside and how the AirPods Pro 3 have changed in comparison to the AirPods Pro 2. [...] To get a look at other components inside the AirPods Pro 3, iFixit essentially had to destroy them because Apple didn't design them to be repaired. Since the first version of the AirPods launched, they've included a battery that is sealed shut with glue, and that hasn't changed with the AirPods Pro 3. iFixit says battery replacements are so difficult that many repair shops won't even attempt to do it. The AirPods Pro Charging Case has the same glued-in battery. There's no way to attempt a battery repair without causing blemishes on the plastic of the earbuds and the casing, because they have to be pried open. Heat needs to be used to melt the adhesive, and there's no easy way to disconnect the flex cable that's inside each earbud. With the need for specialized equipment and the inability to repair the earbuds and the case without causing damage, the AirPods Pro 3 earned a 0 out of 10 repairability score from iFixit.
