Was Your Gmail Account Safe?

More than 300,000 Iranians have had their Gmail accounts compromised. From the report by the investigative firm Fox-IT, the security firm hired to investigate the stolen DigiNotar security certificates, it is clear that as early as July 28, the company was aware that falsified security certificates were in use in Iran. This is one month earlier than the first public notice, which was made by a Google Chrome user in Iran. (Read more background information.)The report, Operation Black Tulip (pdf), states:

Strangely enough, his browser flashed a message telling him that the security certificate he was using to access Google was not theirs. The user went to Google’s help forums to follow up on this and an investigation followed which uncovered a secretive, but highly explosive plot: a security firm in the Netherlands, DigiNotar, had seemingly provided a certificate to “someone” in Iran that allowed access to all secure traffic over Google within Iran.Security bloggers are reporting that the site may have been hacked earlier, in 2009.
