The fuzzer that found https://project-zero.issues.chromium.org/issues?q=componentid:1638259%20%22V8%20Sandbox%20Bypass%22 (and a number of issues prior to that as well) is now open-source: https://crrev.com/c/7580844 It uses pkeys, trap-handling and single-stepping to intercept and mutate in-sandbox reads (see trap-fuzzer.h for details). Definitely had fun writing it!

Big day for the V8 Sandbox:
* Now included in the Chrome VRP: http://g.co/chrome/vrp/#v8-sandbox-bypass-rewards
* Motivation & goals discussed in a new technical blog post: http://v8.dev/blog/sandbox

If there is ever a Sandbox "beta" release, this is it!
