Fraudulent digital certificate for Google web properties used in active attacks

A fraudulent digital certificate that could be used to spoof content, perform phishing attacks, or perform man-in-the-middle attacks against several Google web properties has been discovered by the Google Chrome Security Team.

Microsoft has been immediately notified of the matter and has moved to update its Certificate Trust list (CTL) and all its supported releases of Windows in order to remove the trust of that and two other certificates, as it appears that active attacks using the first certificates have been detected.

“TURKTRUST Inc. incorrectly created two subsidiary CAs (*.EGO.GOV.TR and The *.EGO.GOV.TR subsidiary CA was then used to issue a fraudulent digital certificate to *,” they explained in a security advisory.

Users who don’t have the automatic updater of revoked certificates enabled are advised to download and apply the latest system update, while Windows 8, Windows RT, Windows Server 2012, and Windows Phone 8 users needn’t worry about that – their CTL will be updated automatically.
