The security certificate used by the Superfish add-on installed on its computers Lenovo just broke (Cracked).
Recently, we reported that the Superfish software used by Lenovo generates a security certificate to re-sign all security certificates it receives from HTTPS pages, such as bank pages, effectively allowing access σε πληροφορίες απλού κειμένου στην κίνηση μεταξύ client και server που διαφορετικά θα ήταν κρυπτογραφημένη.
Many security experts who have examined the subject have discovered that the add-on uses the same RSA key (1024 bits) on all devices, which means that if someone manages to break it, they will be able to "read" the encrypted traffic exchanged between a user with a Lenovo user computer and a secure service. This is exactly what he did Robert Graham, CEO of Errata Security.
The researcher used a system with Superfish installed by dumping the data generated by the processes in μνήμη of the system.
After discovery of the encrypted private key of the security certificate used by Superfish, and the certificate itself, tried to verify that the data was protected by a password.
Cracking the password turned out to be a bit more difficult than expected, as it required a modified brute-force program. When Graham had to develop a new brute-force software for the needs of this attack.
He assumed that the password would not be complicated, so he gave the program a search command only between lowercase letters. In less than 10 seconds, he discovered the password that was "komodia."
The password decrypts the root certificate and could be used in man-in-the-middle attacks against Lenovo users who have Superfish installed on their system.
