Ok, I have been doing some thinking in regards to the credibility of this story (even though it has been reported as false).
Firstly, the Chinese government would not have be involved for the following reasons:
1) They gain nothing by causing political instability in North Korea
2) It occured inside the embassy
3) The Chinese internet censorship was reactionary in nature, the posts were being taken down not initially blocked (which if they were going to do something, they would do their best to keep it silent)
So since it alledgely occured inside the embassy, it would indicate a North Korean operation, which again, does not seem likely since it occured inside China. Firstly, this would cause the Chinese to lose face (something which is actually rather important culturally). Face has actually been the root of some of the political instability I might add (it really is that important...and individually, tell someone in China that you love China more than Australia and they light up). Following this, the North Koreans would have political instability, and also have rocky relations with their only ally. Spells certain doom for PRK!
If an assassination attempt was to occur from the North Koreans, it would occur in North Korea. Following similar messages in January about Kim Jong-Un being overthrown circling in the same fashion, this is definately someone's imagination running away with them ("zomg I see so many cars, someone must have died...omg it must be the president" me personally I would have gone for alien coverup but meh 
)
I give your invention the worst score imaginable. An A minus MINUS!
