Iran link to fraudulent digital certificates?
A Dutch company appears to have issued a digital certificate for Google.com to someone other than Google, who may be using it to try to re-direct traffic of users based in Iran.
Yesterday, someone reported on a Google support site that when attempting to log in to Gmail the browser issued a warning for the digital certificate used as proof that the site is legitimate, according to this thread on a Google support forum site.
"Today, when I tried to login to my Gmail account I saw a certificate warning in Chrome," someone using the screen name "alibo" wrote. "I think my ISP or my government did this attack (because I live in Iran and you may hear something about the story of Comodo hacker!)" Alibo then posted a screenshot and the text of the certificate. The screenshot page was not accessible.
In this case the browser of the person reporting the problem warned that there was a problem with the digital certificate. However, it's unclear what triggered the warning and other browsers may not. In that event, a user could end up on a site that purports to be google.com but isn't.
CNET verified that the digital certificate is fraudulent. This Pastebin post details how to verify that a certificate is real and notes that it was issued in July.
The certificate was issued by DigiNotar, based in the Netherlands. Representatives from the company did not immediately respond to an e-mail seeking comment today and an automated message said the offices were closed for the night and offered no voice-mail option. A phone call and e-mail to Vasco Data Security, parent company of DigiNotar, were not immediately returned.
