*** Actors using exploit kits - How they change tactics, (Thu, Nov 19th) ***
---------------------------------------------
Introduction Exploit kits (EKs) are used by criminals to infect unsuspecting users while they are browsing the web. EKs are hosted on servers specifically dedicated to the EK.  How are the users computers directed to an EK? It happens through compromised websites. Threat actors compromise legitimate websites, and pages from these compromised servers have injected script that connects the users computer to an EK server.

*** Windows Sandbox Attack Surface Analysis ***
---------------------------------------------
TL;DR; I've released my tools I use internally to test out sandboxed code and determine the likely attack surface exposed to an attacker if a sandboxed process is compromised. You can get the source code from https://github.com/google/sandbox-attacksurface-analysis-tools. This blog post will describe a few common use cases so that you can use them to do your own sandbox analysis.
