Had some fun finding and exploiting state machine logic bug in af_alg_sendmsg last year, it leads to OOB access, arbitrary write then container escape that unnoticed since 2011

@ekuber Having a chopper to call when you go hiking is definitely nice :D I don't quite get how the principles apply here though: in your opinion, for this particular example, would it be right to require all traits by ::new()?

@ekuber Don't get me wrong, I'm positively amazed by rustc messages in general, and this one is no exception. On the other hand I also like to see how I should approach the API I'm about to use, having a map about the code base before I go down a path that just won't work. I feel like relying on the compiler is like periodically calling a hovering helicopter to get out of the woods, instead of having a proper $5 map.

I suspect that Microsoft pushed out Defender updates that mitigate the exploit.

With current definitions, I've not seen RedSun succeed. No matter how long I wait.

With old definitions, success is pretty quick.

LLMs are just the ultimate IP-violation-machines. I love using them for reverse engineering. I picked up so many projects I abandoned in the past because staring at obfuscated code or assembly got boring and tiresome and felt like an endless endeavor that will never be realistically reverse engineered completely anway.

Now I give Opus or whatever other model enough context, datasheets and tests and it starts reversing. Does it hallucinate and is not always correct? Yeah. But who cares? I am not always correct and misunderstand things when manually reversing stuff as well. We all do.

Gradually building more and more context to be able to reason a bit easier about things you didn't understand yet is exactly what an LLM can incrementally help you with. And gathering more and more information helps both me and the LLM to understand the stuff we are looking at a bit better.

It's so awesome.

@stf "might affect cryptology at some future time or (more likely) in some other world." I forgot about this one lol

#eurocrypt just happened, which reminds me of the eurocrypt 35 years ago held in budapest, which an #NSA cryptologist was attending and giving a scorching #report in the internal cryptolog newsletter of the nsa: https://scottaaronson.blog/?p=2059

would be interesting to see the latest cryptolog report on this latest edition...

Oh look, it's Patch Tuesday. Again.

"This is an elegant use of Rust's trait system to separate construction from operation, with compile-time guarantees that the right capabilities are available when needed." - LLM

Except both me and my IDE are in the dark about what kind of object Foo::new(obj) *really* expects until I get the compile error?

(Foo::new() only prescribes EasyTrait, but Foo::bar() requires TrickyTrait)

Redditors have caught Google secretly updating its Chrome terms of service to remove a line that guaranteed that local AI models won't send data to Google servers.

That's now gone, meaning your local AI sends data to Google, so it's not that local.
