Can Palo Alto firewall prevent/intercept this JS in Github DDoS event?

L4 Transporter

Dear Sirs,

On March 26 the Github has been attacked by a five-days DDoS. Many people pointed out that an javascript infected from China was very suspicious because it would connect to Github per 2 seconds. University of Toronto’s Canada Centre and Citizen Lab call this weapon of China as “The Great Cannon”.

The problem is, can Palo Alto firewall prevent/intercept this JS? If TP is enable.

Yes, Palo Alto can mitigate this type of attack.  You can see the general deployment recommendations in these documents.

Thank you, Steven.

I thank it's a misunderstanding.

Any traffic pass through "the great wall" of China, could be replaced an JS about 1.75% chance. My question is can the visitor prevent/intercept the fake javascript?
