A 1.3Tbs DDoS Hit GitHub, the Largest Yet Recorded

A 1.3Tbs DDoS Hit GitHub, the Largest Yet Recorded | Security & the Internet of Things: IoT, OT, IIoT | Scoop.it
On Wednesday, a 1.3Tbps DDoS attack pummeled GitHub for 15-20 minutes. Here's how it stayed online.
Judy Curtis / SIPR's insight:
Lily Hay Newman writes in Wired about the attack on the developer platform GitHub on the last day of February 2018 - the most powerful distributed denial of service attack recorded to date. To attackers, the beauty of memcached DDoS attacks is there's no malware to distribute, and no botnet to maintain. 

Newman writes: The web monitoring and network intelligence firm ThousandEyes observed the GitHub attack on Wednesday. "This was a successful mitigation. Everything transpired in 15 to 20 minutes," says Alex Henthorne-Iwane, vice president of product marketing at ThousandEyes. "If you look at the stats you’ll find that globally speaking DDoS attack detection alone generally takes about an hour plus, which usually means there’s a human involved looking and kind of scratching their head. When it all happens within 20 minutes you know that this is driven primarily by software. It’s nice to see a picture of success." 

 GitHub continued routing its traffic through Prolexic for a few hours to ensure that the situation was resolved. Akamai's Shaul says he suspects that attackers targeted GitHub simply because it is a high-profile service that would be impressive to take down. The attackers also may have been hoping to extract a ransom. "The duration of this attack was fairly short," he says. "I think it didn’t have any impact so they just said that’s not worth our time anymore." 

Until memcached servers get off the public internet, though, it seems likely that attackers will give a DDoS of this scale another shot.
