Microsoft sends an update patch to revoke all DigiNotar root certificates

Microsoft released an update patch numbered KB2607712 to remove the DigiNotar root certificate. DigiNotar is a company that provides root certificates. Last month, several security agencies said anonymous hackers attacked DigiNotar's servers, making it easy for user accounts to be hijacked by hackers. Subsequently, DigiNotar admitted that it was hacked. In response to this security incident, Microsoft responded quickly. According to the survey, Microsoft believes that all DigiNotar certificates are not reliable. The company released security bulletin KB2607712 on August 29 this year, removing two DigiNotar root certificates from the certificate trust list, making it impossible for IE users to access websites with certificates issued by DigiNotar. A few days ago, the relevant patches have been provided for download. The Microsoft patch revokes the DigiNotar certificate KB2607712 for Windows 7 SP1, Vista SP2, XP SP3, and the server version systems Windows Server 2008 R2, Windows Server 2008 and Windows Server 2003. Dave Forstrom, head of Microsoft's Trustworthy Computing Division, said: Microsoft believes this is an industry issue and we are actively working with certification authorities, governments and related software vendors to provide protection and assistance to our customers. Microsoft will continue to investigate this issue in depth. At the time of writing, Google, Microsoft, and Mozilla have blocked or removed DigiNotar's fake certificates.
