more exciting stuff coming to libAFL @aflplusplus.bsky.social , including a binary-only ASan implementation in Rust for QEMU and integration with the unicorn emulator!
reminds me of how @dmnk.bsky.social and I got the unicornafl rust bindings up and running to fuzz some basebands 5 years ago

After playing around with @bevyengine.org engine - looks like its concepts are super similar to what we have in #LibAFL @aflplusplus.bsky.social (its 'ECS' == our AnyMap)
This makes sense, we took inspiration from game engines initially, but it's still interesting to see.
