DigiNotar SSL Certificate Hack

Microsoft Security Advisory (2607712)
Fraudulent Digital Certificates Could Allow Spoofing
Published: August 29, 2011 | Updated: August 29, 2011

Microsoft is aware of at least one fraudulent digital certificate issued by DigiNotar, a certification authority present in the Trusted Root Certification Authorities Store, on all supported releases of Microsoft Windows. Although this is not a vulnerability in a Microsoft product, Microsoft is taking action to protect customers.

Microsoft has been able to confirm that one digital certificate affects all subdomains of google.com and may be used to spoof content, perform phishing attacks, or perform man-in-the-middle attacks against all Web browser users including users of Internet Explorer. Microsoft is continuing to investigate how many more certificates have been fraudulently issued. As a precautionary measure, Microsoft has removed the DigiNotar root certificate from the Microsoft Certificate Trust List.

All supported editions of Windows Vista, Windows 7, Windows Server 2008, and Windows Server 2008 R2 use the Microsoft Certificate Trust List to validate the trust of a certification authority. Users of these operating systems will be presented with an invalid certificate error when they browse to a Web site or try to install programs signed by the DigiNotar root certificate. In those cases users should follow the instructions in the message. Microsoft will release a future update to address this issue for all supported editions of Windows XP and Windows Server 2003.

Microsoft is continuing to investigate this issue and may release future updates to help protect customers.


V3.0 (September 6, 2011): Revised to announce the release of an update that addresses this issue.


Hackers may have obtained more than 200 digital certificates from a Dutch company after breaking into its network, including ones for Mozilla, Yahoo and the Tor project, a security researcher reported today.

The count is considerably higher than DigiNotar has acknowledged. Earlier this week, a company spokesman said that “several dozen” certificates had been acquired by the attackers.
