Google has identified and blocked unauthorized digital certificates for a number of its domains issued by the National Informatics Centre (NIC) of India, a unit of India’s Ministry of Communications and Information Technology. The use of rogue digital certificates could result in a potentially serious security and privacy threat that could allow an attacker to spy on an encrypted communication between a user’s device and a secure HTTPS website. Google became aware of the fake certificates last Wednesday on July 2 and within 24 hours, the Indian Controller of Certifying Authorities (India CCA) revoked all the NIC intermediate certificates.
