This is one of the fastest documented case of an immediate weaponization in the wild, possibly thanks to the detailed instructions left by Hacking Team.


The exploit also works in Firefox (latest version):


Only a few minutes later, Angler EK began firing the new zero-day (this was also reported by other sources):


Malwarebytes Anti-Exploit users were already protected against this attack.
