At TechEd day 4 sessions were of Anatomy of a Hack (by Jesper Johansen) and Inside Windows Server 2008 R2 Virtualization Improvements and Native VHD Support (by Mark Russinovich). Both sessions were delivered in the Auditorium.
Jesper Johansson showed an deep look into Antivirus XP 2008. You might already be familiar with this specific piece of malware when you’re subscribed to Donna's SecurityFlash. It’s a nasty piece of software, that does a really good job at tricking users into installing it, running it and paying for it. I’ll never look the same at the (Windows) Security Center again.
I attended the session by Mark Russinovich together with Marc van Orsouw. This was a level 400 session on Hyper-V improvements in Windows Server 2008 R2, including live VM migration, hypervisor power management support and new hardware-assisted guest memory management. Windows 7 booting from VHD was a nice feature that was shown, by looking at the way Mark’s currently booted Operating system was actually started from a VHD.
