Flame Malware Signed By 'Rogue' Microsoft Cert, Once Again Highlights Problems With Relying On Certs

from the time-to-move-forward dept

We've discussed in the past just how dangerous our reliance on Certificate Authorities "signing" security certificates has become. This is a key part of the way we handle security online, and yet it's clearly subject to abuse. The latest such example: the now infamous Flame malware that targeted computer systems in the Middle East was signed by a "rogue" Microsoft certificate -- one which was supposed to be used for allowing employees to log into a remote system. Microsoft rushed out a security update over the weekend, but that doesn't change the core problem: the whole setup of relying so heavily on secure certificates seems to be increasingly dangerous.

    DNSSEC is only complimentary to a secure connection between a host and client as it only verifies that the host is correct from the authoritative name server. Encryption between the host and client is still necessary. With an incident like DNSChanger or a poisoned caching server, you could still be lead to a false server with a false certificate and become compromised.
    The only solution that I recommend is simply running your own caching server, and setting up monitoring of DNS records to alert you of any changes. This however doesn't scale very well outside of an office/home environment, and takes some technical skill on the part of the end user.
