    Talk done! If you have any more questions, and I will be seating at the burger joint just in front. We “heard” they serve pretty good cocktails as well... :)

    Miss you

    I once did a bug bounty for some lame hipchat shit because it was seriously so dumb I had to tell them. Moral of the story: companies with `swag' prizes, please use only the highest quality fabric. I couldn't even sleep in that t-shirt. Gross.

    I am delighted to announce that and I will be presenting at PacSec together next November in Tokyo. Shane and I have been working on scaling vulnerability discovery for almost 20 years and it’s time for us to share what we learned!

    InfinityHook is a pretty neat piece of software for Win10, allows you to hook syscalls, context switches, and many more kernel events using ETW via cc

    I'm publishing some 🔥 research today, a major design flaw in Windows that's existed for almost *two decades*. I wrote a blog post on the story of the discovery all the way through to exploitation.

    Undocumented MSVC flags to emit an AST. Handy for many purposes, right now I'm evaluating methods to compare front end AST output for equivalent representation when refactoring or lang-fuzzing.

    UniTaint - A quick PoC I made last year to see if VMProtect is resistent to taint based attacks. Based on , BeaEngine and a custom tainter. Take it as it comes!

    I only wanted to check whether call gates still work on 64-bit x86. They do. (Why?) I ended up microbenchmarking and writing a blog post about system call entry/exit mechanisms on x86.

    Today is day 91, so the issue is now public. I consider this relatively low severity, but you could take down an entire Windows fleet relatively easily, so it's worth being aware of.

    I finally wrote a small tool I've wanted for a long time: A parallel testcase minimizer. It's called halfempty, and I'm already finding it useful as part of my fuzzing workflow. /cc

    A while back I prototyped a "Twitch plays binary exploitation" setup. Would anyone be interested in seeing this become a real thing? The general idea is that whatever people type in chat would get sent to stdin (one user at a time, with some kind of queue).

    We drove the van down the day before, partly due to my fear of flying, partly to do early signals collection along the northeast corridor, and partly to make it to the NSA crypto museum :)

    On this day in 1998 seven hackers drove a van from Boston to Washington DC to testify to Congress about weak computer security in government. Happy L0pht Day!
