I would totally think these guys are state-sponsored.
This: "Members wield advanced, zero-day attacks that exploit security vulnerabilities in Oracle's Java, Microsoft's Internet Explorer, and other widely used software frameworks or applications. The report said their tactics and exploits are far more advanced than those of the Comment Crew, a China-affiliated hacking crew that researchers from security firm Mandiant said has siphoned terabytes of sensitive data from 141 organizations over the past seven years."
And this: "Team Moudoor, named for the trojan they use, takes a large-scale approach that broadly penetrates organizations in the financial industry, local and federal government organizations, and organizations related to healthcare, education, and law. Team Naid, by contrast, is more of a special operations squad that keeps a low profile so it can save its resources for the highest-profile targets in the defense industrial base."
In short, these guys are highly, highly skilled and specialized ... and a specific attack target and vector.
This is not a bunch of script kiddies looking for fame and glory.
