It’s a fairly common tactic used to force targets offline. GitHub is a common target — the Chinese government is widely-suspected to be behind a five-day-long attack in 2015 over its hosting of software to bypass its internet censorship system — and this newest assault tipped the scales at an incredible 1.35Tbps at peak. A blog post retelling the incident, GitHub said the attackers hijacke...
