Arbitrary Code Guard is a strict implementation of W^X for Windows. Warbird is a code obfuscator used for DRM that can be abused for an ACG bypass. Despite being a two line fix, the actual fix ends up being much more involved. Wide ranging talk on security, Windows internals, browsers, jits, etc.
Pretty ridiculous. Microsoft added DRM code to windows, which introduced security holes that can’t be patched in any old version of Windows. If you get a new version of Windows (Fall Creator’s Edition), then you don’t have this security hole on your PC.
Nice.
