I think the Bitlocker "vuln" is a good reminder not to use vendor provided encryption for any sensitive data. https://github.com/Nightmare-Eclipse/YellowKey/ You load a specific file onto a flash drive, plug it into a Bitlocker encrypted computer, reboot it while holding a key combination, and it pops up a command prompt with full access to the encrypted volume. There's no way this isn't a backdoor.
this exploit works only if you dont use a PIN/password for your Bitlocker and the volume automatically unlocks
so it gives you access to an encrypted volume which automatically unlocks anyway
the only difference is that it immediately gives you root access to the volume instead of having to go through the Windows login procedure - this might be a stolen laptop you dont have an account on
The author claims the exploit also works with TPM+PIN, he just hasn't released the PoC:
> Second thing is, No, TPM+PIN does not help, the issue is still exploitable regardless, I asked myself this question, can it still work in a TPM+PIN environment ? Yes it does, I'm just not publishing the PoC, I think what's out there is already bad enough.

I don't think that's true. Some vendors have a better track record than others. Nobody's popped the storage encryption on iOS or MacOS devices yet AFAIK; and the fact that it's tied to a hardware secure element makes it pretty strong.
Ah yes, the bizarro world where systems are normally unhackable so the default assumption is impenetrable security and you need to prove they are insecure.
Thank god this is not the world where things get hacked all the time and where any claim of meaningful security is a extraordinary claim that demands extraordinary evidence and proof before credibly asserting it, but everybody just ignores that part and just pinky promises it and people believe them.
I don't see anything on the linked page that supports a conclusion that NSA has successfully broken the encryption at rest of an Apple device's storage since they introduced the secure element.
Prism targeted network communication to my knowledge, hence the data wouldn't be siphoned from at rest encrypted devices. Instead it would've been leaked before it was copied to that local encrypted device, whenever it was transmitted over the wire. Eg when your background task uploaded it to iCloud or similar.
That warning also doesn’t render right on my
iPhone (the buttons are overlapping slightly), and I don’t recall seeing it on other repos. Is it new/bespoke?

Care to share a quote?
There doesn't seem to be any other plausible explanation. The reckoning needs to come and people need to stop using their products for good.
Would love a whistleblower to explain which part of the government or company forced it.
