I'm confused. The article from September 1 linked to here is strangely future-tense ("But the firm’s latest investment in 10,000 of the company’s H100 GPUs dwarfs the power of this supercomputer....This AI cluster, worth more than

The really obvious thing, if you watch the Freeze "best of" clip, is that most people have terrible running form. In most cases, I suspect I could tell who has a chance and who doesn't simply by looking at one stride from eac

What I understand the author to be saying is that the SE will unwrap locally stored synced credentials and then encrypt them to the previously-established iCloud sync key. It doesn't really matter if the storage of the actual wrapped k

I'm not sure how to relate that to the slashid article, which notes, > In other words, the private key used to encrypt kSecAttrSynchronizable keys in the Secure Enclave is backed in iCloud. As such, when a new device needs to restor

I don't think the distinction is meaningless, though, as I said, I do agree that exportable keys are more vulnerable than non-exportable. What I understand the iCloud scheme to guarantee is roughly: 1. The TEE will not export keys exc

I don't think most services are requiring specific vendor attestation for Passkeys. I think most services are requiring authenticators that support user verification. Does your USB security key support uv? E.g. https://www.y

If someone has code execution in your browser, they can just steal your authentication cookies. They don't need your Passkey. It's true that unsynced/hardware-bound credentials can help mitigate such attacks, but they cannot

I think you're the one who misunderstands. Synced Passkeys are, in the Apple world, still stored in a Secure Element; they just are exportable. https://www.slashid.dev/blog/passkeys-deepdive/ describes this f

I didn't find it sensationalist. Obviously, like, being born in a country with a poor healthcare system might have a bigger impact on your morbidity/mortality in some cases than dietary changes, but it's hard for people to ch

I was struck while recently reading David Grann's "The Wager" by how little people understood scurvy at the time. Grann writes about how some doctors believed it to be a reaction of the body to being away from solid land for

A core argument the post makes is that TPMs are insufficient for verifying full stack integrity and thus ineffective for FDE. (Eg by exploiting vulnerable drivers, an attacker can dump the disk encryption key from kernel memory.) But in suc

Half agree. Successful founders get to remain CEO (or CTO, or whatever). Unsuccessful ones don't: their investors push them out, or the company tanks. Along the way to obtaining any position, there's a lot of partially correlated
