Since our last MSRC blog post, we’ve received questions on the nature of the cryptographic attack we saw in the complex, targeted malware known as Flame. This blog summarizes what our research revealed and why we made the decision to release Security Advisory 2718704 on Sunday night PDT.

With the era of freely available IPv4 addresses nearing its end, I'm pleased to see that 2012 appears to be the year when the IPv6 Internet will finally reach maturity and launch into wide-scale commercial use.
