Komodia Certificate Compromise affects Superfish and other software (Feb 23,2015)

The private key used by Komodia SDK that ships pre-installed with some Lenovo laptops has been compromised, and presents a breakdown of trust between web browsers and secure websites. Komodia SDK-based software establishes, what is essentially a Man-in-the-Middle (MitM) between your browser and the HTTPS/SSL sites you visit, for example, like your bank. It creates a public-private key pair and inserts the public key as a Root Certificate Authority (CA) certificate on your machine. This means that an attacker can use this cracked private key to create spoofed SSL Certificate for a spoofed site. The Komodia SDK-based software will trust the certificate that has been installed into your Root CA store and you will not notice a thing. The only thing you will notice if you click on the lock icon in your browser address bar is that the certificate from your bank has an “Issued by: Superfish, Inc.”. Other software that uses the Komodia SDK includes PrivDog and others. PrivDog, for example, is advertised as a privacy and secure browsing program. Like Superfish it creates a MitM between your browser and secure websites.
