Yes. However, there is no definitive evidence that these threat actors are state sponsored, so the fact they're from China doesn't mean that they are China, technically. But the circumstantial evidence is convincing.
Contrary to what samstave said, Chinese APT aren't particularly sophisticated. They do leave a lot of footprints behind, although for obvious reasons that data is generally not made public.
Personally, no. This information came to me from head of netsec at lockheed in our meetings. It was conveyed in phone conversation on the netsec con calls.
That's odd, because through the media and Internet forums anywhere I can only see name pointing, not strong evidence.
If you ever have time, trace back all the "China hacking" reports, they all came from non-tech sources, just authoritive accusing. Blame China is obviously the most safe and easy assumption, because Chinese people rarely care or hear foreign voices anyway.
But do you happened to know that Chinese Internet was one of the largest malware & botnet victims in the world? If you subscribe full-disclosure you can see lots of mass security issues happening in China everyday.
No, it isn't. The Chinese themselves are documenting the attacks. They made a documentary about it. It was a story here on HN. It's not exactly a secret.
Yes, it's documented, but it's DoS Falun Gong servers, the same stuff like Anons with LOIC. But stealing IP from company for political or commercial motives? You need much more than DoS.
First of all, my experience in this matter occured in 2007.
Second, if you do not think that MASSIVE governmental cyberspying is taking place between pretty much everyone, then you are fooling yourself.
We have already seen the most amazing display of US/Israel cyber capability with Stuxnet.
THey have been even actively ASSASSINATING nuclear engineers in Iran for fucks sake!
Just because I have been aware of China's attacks on Lockheed since 2007, and likely the first time this type of thought entered your head in ~2012 doesn't make this some propaganda campaign.
OF COURSE china is under attack from the US, Israel, France, the UK.
I am not sure if you are aware of it - but a resource war is looming in the not too distant future.
While China has secured MASSIVE natural resources and made themselves the center of all consumer/industrial manufacturing (aside from heavy industry in Germany) - the US/Israel faction has spent trillions on advanced weaponry and securing fuel resources.
So that war that is coming will be a war of attrition: US/Israel with secured fuel for N years, China with massive natural and human resources.
Right now the chess game of getting everything in place is what is underway.
While I agree a war is looming, but simply accuse China without decent evidence is just like "USA Imperialism" hatred in China without any rational reasons.
And just for the record, China relies heavily on resource import, too. And the documentary shows exactly how poor Chinese government hacking is.
