a) Big US enterprises are under attack from state-sponsored actors on a daily basis, so it's not that weird. It's not like the NSA weren't caught with their hands in the cookie jar either.

b) If you name the state you think is behind it, you better be ready for the diplomatic repercussions between the US government and the rogue state, as well as potentially stopping doing business in that state (see Google and China)

a) Can you point to an article were I can learn more about examples of big US corps being attacked by US sponsored actors?

It's a quite interesting topic indeed.

NSA infiltrates links to Yahoo, Google data centers worldwide, Snowden documents say

https://www.washingtonpost.com/world/national-security/nsa-i...

We can assume that the US government is not the state-sponsored actor in the OP, because their attack has already been publicly known for some time. This one is probably China or Russia.

Does NSA tapping Google's fiber count: http://www.bbc.com/news/world-us-canada-24751821

It's rarely written about, in part because the private companies don't want to share details.

Buy a beer for someone who has worked security for a big firm and they can tell you all about it.
