BTW #3 is probably worth paying attention to here: 3. Safety Considerations
Due to the highly sensitive nature of these leaked materials, we strongly advise anyone who chooses to download and analyze them to take proper operational security precautions. It may be possible that these files may contain potentially risky content and accessing them in an insecure environment could expose you to surveillance or malware.

Please consider analyzing these files only in an isolated (virtual) machine without internet access.

@briankrebs seem a lot of that is a rpm mirror?

Don't treat this as "Haha we got China's secrets!!"

Treat this as "Anyone wanting to compromise systems of threat/privacy/cybersecurity researchers will be trusting to plant bugs in this dataset."

Your privacy and security may depend on it.

@briankrebs
And by "trusting to plant" I meant "trying to plant" but autocorrect had other ideas.

(Autocorrect and auto suggestions have gotten completely out of control. Try shopping for a Boroscope online and see how many horoscope books you get in your results!)

Somehow I missed this Wired story on the leak from Sept 8

Massive Leak Shows How a Chinese Company Is Exporting the Great Firewall to the World

Geedge Networks, a company with ties to the founder of China’s mass censorship infrastructure, is selling its censorship and surveillance systems to at least four other countries in Asia and Africa.

WIRED
@briankrebs I hear envy that the Chinese are allowed to sell the good stuff, while our drug^H^H^H^H I mean network safety for whole countries sellers are frustrated with having to sell under the table due to export restrictions.

@briankrebs

The content may or may not be legit, but it does demonstrate that it is possible to punch a hole thru the GFW if you have root. Or you are insider.

@briankrebs If #NATO countries need a deterrent, this is what to target. Demonstrate the capacity to invert the function of the Great Firewall, to block propaganda and surveillance and allow accurate but prohibited information, in response to intrusion into infrastructure.
