Something Old, Something New, True Blue

Friday, October 15, 2010

This year marks the tenth BlueHat at Microsoft, and my sixth round in participating in the event that has been so instrumental in keeping Microsoft developers and executives in touch with the pulse of security research outside Microsoft, and serves as one of the key crossroads for the exchange of ideas from our internal security experts to the outside world.

September 2010 Security Bulletin Release

Monday, September 13, 2010

Hi everyone, With this month’s bulletin release, I want to highlight the great work done through our partnerships in the Microsoft Active Protections Program (MAPP). MAPP represents our commitment to community based defense and a shared sense of responsibility to help protect the computing ecosystem. In July of this year, the Stuxnet malware emerged onto the threat landscape and resulted in the release of an out-of-band security update, MS10-046, to address a zero-day vulnerability the malware used to compromise systems.

Tuesday, August 31, 2010

Hi everyone, Since we released Security Advisory 2269637 on August 23, we’ve continued to conduct an investigation not only into our own affected products, but also into how we can best help to protect customers given DLL preloading also affects some third-party applications.
