You do realize that there was a well-documented case of the Chinese government setting the Great Firewall of China to send a altered Baidu javascript to users outside of China to engage in a massive DDoS of github in an attempt to pressure github into removing two projects that the Chinese government disapproves of earlier this year, right? It took github offline entirely and they didn't even have most of the attack deflected until 3.5 days in. Google the words github baidu ddos and you'll have your pick of legitimate sources. It's well known and well documented within the tech community. The mainstream media mostly ignored it.
