In a blog post retelling the incident, GitHub said the attackers hijacked something called “memcaching” - a distributed memory system known for high-performance and demand - to massively amplify the traffic volumes that were being fired at GitHub. GitHub is a common target - the Chinese government was widely suspected to be behind a five-day-long attack in 2015 - and this newest assault tipped the scales at an incredible 1.35Tbps at peak. It’s a fairly common tactic used to force targets offline.
In a growing sign of the increased sophistication of both cyber attacks and defenses, GitHub has revealed that this week it weathered the largest-known DDoS attack in history.ĭDoS - or distributed denial of service in full - is a cyber attack that aims to bring websites and web-based services down by bombarding them with so much traffic that their services and infrastructure are unable to handle it all.
