From Fire Eye "this actor has the tradecraft abilities and resources"
Exploits are going to be happening more and more frequently as foreign spy agencies worldwide are forced to emulate what the NSA is doing (spying on friendly nations, their citizens and their companies) in order to maintain their own national security and national interests.
From the Fire Eye blog:
"This threat actor clearly seeks out and compromises websites of organizations related to international security policy, defense topics, and other non-profit sociocultural issues. The actor either maintains persistence on these sites for extended periods of time or is able to re-compromise them periodically.
This actor also has early access to a number of zero-day exploits, including Flash and Java, and deploys a variety of malware families on compromised systems. Based on these and other observations, we conclude that this actor has the tradecraft abilities and resources to remain a credible threat in at least the mid-term."
