As you might remember, on Match 16th Microsoft together with other industry players was successfully able to take down the Rustock botnet and thus significantly reducing the spam level.

We now just published a special Intelligence Report on this botnet:

Read an overview of the Win32/Rustock family of rootkit-enabled backdoor Trojans background, functionality, how it works, and threat telemetry data with analysis for 2010 to May 2011. This document provides legal and technical action used to takedown the Rustock botnet and how to detect and remove the threat using Microsoft antimalware products.

You will find it here.

You heard about the launch of Office365 recently and I hope you read the blog post on the application of the Cloud Computing Security Considerations to the private. cloud. If not, here it is: Security Considerations in a Private Cloud

To complete the series now, we released an additional paper on how these considerations can be applied to Office 365. It is not about the security features of Office 365. It is about how a the responsibilities between the customer and us can and shall be split. This is a really interesting paper in my opinion: Addressing Cloud Computing Security Considerations with Microsoft Office 365.

Additionally, we took a deeper look at the Cloud Security Alliance’ Cloud Control Matrix (CCM) at provided an answer for each question/control raised in this document: Standard Response to Request for Information - Security and Privacy.

These are all steps to provide you with the necessary transparency to get into the public cloud and on Office 365!

I know, I have been fairly slow in blogging currently but I was fairly busy with a few cool projects (which I will disclose later) and – time flies if you are having fun

Just a quick one:

The MMPC on Facebook and Twitter

The Microsoft Malware Protection Center (MMPC) officially launched its Facebook page and Twitter account. From this Welcome page, you can read the latest blog posts, see the latest Twitter feeds, and find out what threats most affect your desktop.

A very good overview over the way we run Microsoft’s Cloud. The interesting thing is – if you look at the video – that most customers are still running their datacenters on generation 1-2, which means that the efficiency (labor as well as energy) we can deliver is significantly higher – not talking of our security.

Enjoy this tour:
