  • It doesn’t already have to be running. BitLocker retrieves its keys from TPM by default, so just booting a device will place the keys in memory.

    To minimize downtime, abruptly restart the target system during the Windows boot process, specifically before the login screen appears, as this approach has proven effective in scenarios involving the retrieval of Full Volume Encryption Keys (FVEKs).

    By kernel-level debugging with WinDbg, the researcher observed BitLocker operations during the Windows boot process, which revealed that while Microsoft attempts to erase encryption keys using functions like SymCryptSessionDestroy, some keys persist on the heap, potentially due to incomplete key destruction mechanisms.


  • Is this really a BitLocker issue or more an issue inherent in the hardware design?

    EDIT: Okay, looks like Microsoft could do better:

    But maybe the hardware/UEFI should immediately wipe memory upon restarting anyway…?

    I expected something more shocking when I read “working with Russia”.

    Kagi uses multiple search backends, and of course it needs to forward search terms to these backends. These backends probably can’t trace the searches back to the individual Kagi user though, but Yandex could still analyze search trends for example.

    What’s worse is that - unless they use Yandex’ API for free - customers indirectly (and likely unknowingly) support a Russian company with their paid Kagi subscription.

    Kagi should at the very least release a statement about this claim.


  • This being displayed as “Unknown” is likely just a bug or an app you (very) recently uninstalled. And you probably opened the camera app by accidentally swiping right to left on the lock screen. Even just a slight swipe will launch the app so it’s ready when you’re done swiping.

    And I’m not even sure what you’re talking about regarding your QR code.

    Android is not de facto superior to iOS, nor is the opposite the case.

    If you’re really that paranoid, even GrapheneOS on a Pixel shouldn’t calm you down because it also requires proprietary firmware by Google (and possibly other vendors) to run on these proprietary devices. In this case my advice would be to stop using smartphones altogether and rely on open source computers (couple of RISC-V options out there I think) for your computing needs.
