    This is the place they direct researchers to report bugs. If they don’t want to pay out for MITM, that’s fine, but they should still be taking out-of-scope reports seriously

    Apple CPUs do decode instructions into micro-ops. https://dougallj.github.io/applecpu/firestorm.html

    Chrome doesn't allow it - local network services have to opt-in to being fetchable from public sites ( https://github.com/WICG/private-network-access ), although they're replacing …

    Especially the fact that he says the toolchain is now available for download (which lends credibility – if they're willing to share it so people can see the quality of output it pr…

    As noted in the article I reversed the protocol for a related Goodix device (which was on Intel so used actual SGX instead of the white-box): I used the firmware update system to i…

    They mention that compiling one crate at a time (-j1) doesnt give the 7x slowdown, which rules out the object file/caching-in-rustc theories... I think the only explanation is the …

    It is in fact documented that you can't do this: "Currently the default global allocator is unspecified. Libraries, however, like cdylibs and staticlibs are guaranteed to use the S…

    Presumably the metabase instance also has credentials to access some databases, some of which may be have enough privileges to also get RCE on the database machines (as well as mes…

    I found something which is clearly a security fix, using the same idea but more naive: just diffing at the lengths of the decompiled files. It's not at all clear how the issue I fo…

    Oh, I didn't mean to imply you can, just that it's 404... presumably it exists in a repo checked out on someone's machine, and maybe in a separate private Github repo.

    They haven't released the source, and the compiled versions are non-trivial to diff (e.g. there are nondeterministic numbers from the clojure compiler that seem to have changed fro…

    llama.cpp runs on the CPU, not the ANE or GPU.

    I don't believe so – from a quick glance it seems that supervisor requests are proxied through the normal HA port, and the supervisor doesn't have it's own port except for the Obse…

    Shodan lists 125,000 HA installs exposed to the internet (though I don't know how accurate that statistic is, nor what fraction have a Supervisor) https://www.shodan.io/search?quer…

    As a random example, if your Microsoft account is OAuthed to a GitHub login, and you log in through that, the popup browser just takes you back to a Microsoft account settings page…

    I'd also like to see motivating examples of specific things it does find (that LLVM doesn't), even if that's not a representative benchmark

    Android's has an app signing system which isn't dependent on Google Play. Updates to a given app have to be signed with the same certificate as previous versions.

    Have you considered making the website actually show the comments instead of pinning yourself on every large post?

    unfortunately this is a real thing the US imposes on the world (it's called Secondary Sanctions)

    In fairness, filecoin is linked on the IPFS homepage (though it is less prominent than I remember)
