project:rosenbridge reveals a hardware backdoor in some desktop, laptop, and embedded x86 processors.
21:01
<
q3k >
The backdoor allows ring 3 (userland) code to circumvent processor protections to freely read and write ring 0 (kernel) data. While the backdoor is typically disabled (requiring ring 0 execution to enable it), we have found that it is enabled by default on some systems.

tl;dr apparently some VIA C3 CPUs have a backdoor

is it too much to ask for the people doing these things to understand the normal meaning of "core"
21:10
<
shapr >
I use fireyfly's tools
21:11
<
sorear >
this is tightly integrated with instruction fetch, it's a non-standard extension of x86 that breaks the security model, it is not a "non-x86 core"

cantor.dust is really cool

I don't care if it works or not, it looks like the best screensaver ever

jn__: there's a tool that does something very similar
21:25

q3k >
jn__: written by Redford, who really wanted a cantor.dust that works
21:25

jn__: although i've heard they're basically doing a rewrite sooner than later, as they wrote themselves in some ugly corners with the codebase
