Virtualization is the future (and often the present) of large-scale IT, but like any technology, it has its share of flaws and shortcomings. Today, as we near the beginning of Black Hat USA 2014, we highlight three Briefings that explore the world of virtualized systems... more specifically, how to break and/or protect them.

Hypervisors are here to stay and promise to shrink the attack surfaces of exposed systems. But Rafal Wojtczuk has been breaking them for eight years, and, oh, does he have some tales to tell. Poacher Turned Gamekeeper: Lessons Learned from Eight Years of Breaking Hypervisors will begin with a trip down memory lane, revisiting major hypervisor breakouts and throwing in a few new exploits, too. Later, he'll examine hypervisor security; does it really live up to the promises? Not at all. In fact, he'll reveal why he believes most hypervisors aren't built with security in mind, as well as his suggestions to harden them.

OpenStack allows you to manage a cloud of VMs, and it has grown into a widely adopted platform. The issue with having a centralized IaaS is that, if you compromise the management cluster, you can attack everything it controls, which is a lot at Yahoo scale. How do you keep your OpenStack cluster safe? What do you do when a management system, hypervisor, or VM is compromised? OpenStack Cloud at Yahoo! Scale: How to Avoid Disaster will discuss how to harden your cluster and make large breaches less likely. And if a breach does occur, you'll find out how to contain it. Bonus: Examples will be drawn from Yahoo's massive deployments of OpenStack clusters.

Finally, it's an arms race between malware authors and forensics experts, and dynamic analysis (sandboxing) is one of good guys' best weapons. But malware authors are evading it in ever-increasing ways. What to do? Full System Emulation: Achieving Successful Automated Dynamic Analysis of Evasive Malware will be a 101, a 201, and possibly a 301 on leveraging full-system emulation, showing you the pros and cons of this methodology, as well as intel on the latest malware evasion techniques observed in the wild.
