‫ Latest Firefox version adds protection against rogue SSL certificates

According to “techworld”, Mozilla has added a defense in its latest version of Firefox that would help prevent hackers from intercepting data intended for major online services.
The feature, known as certificate key pinning, allows online services to specify which SSL/TLS (Secure Sockets Layer/Transport Security Layer) certificates are valid for their services. The certificates are used to verify a site is legitimate and to encrypt data traffic.
In theory, that allowed the hackers to set up a fake website that looked like Gmail and didn't trigger a browser warning of an invalid SSL certificate. Security experts have long warned that attacks targeting certificate authorities are a threat.
Certificate pinning would have halted that kind of attack, as Firefox would have known Diginotar shouldn't have issued a certificate for Google.
In Firefox 32, "if any certificate in the verified certificate chain corresponds to one of the known good (pinned) certificates, Firefox displays the lock icon as normal," wrote Sid Stamm, senior manager of security and privacy engineering at Mozilla, on a company blog.
"When the root cert for a pinned site does not match one of the known good CAs, Firefox will reject the connection with a pinning error," he continued.
The "pins" for the certificates of online services have to be encoded into Firefox. Firefox 32, released this week, supports Mozilla sites and Twitter.
