Signing device question:

I know there is a laser attack that has been used to compromise secure elements on a number of devices. I am not certain what the current status is.

Which devices with secure elements are affected and which are not?

Yeah that's the attack. I'm curious if there's a list or article somewhere showing which hardware devices are vulnerable and which are not.

Talking a bit above my comfort, but I’m pretty sure they’re all vulnerable to the super high cost laser attack, but it costs 150k+ to do and takes some time. At least that’s what I remember.

Good thing 150k is higher than we'd ever see for Bitcoin's whole market cap, let alone a single wallet

I've heard that nostr:nprofile1qqs9v9et20mnqagtgrnrc5qmzcrgmkt2y3087p23vawqlmyczlhfdcqpz9mhxue69uhkummnw3ezuamfdejj7wq5uga might not be because it has two secure elements, but I don't know enough to ask the right question.
