IT Web reports: “Developer platform GitHub was hit by 1.35 terabits per second of traffic all at once. It has been described as the most powerful distributed denial of service (DDOS) attack in history, and employed a DDOS technique that is growing in popularity as it needs no botnet—a memcashed amplification attack. This type of attack sees criminals send spoofed requests to vulnerable memcached servers that also have UDP support enabled. Due to the way memcached works, the servers respond to the requests with far larger packet sizes. The servers then send the large packets to the victim IP, which overwhelms the victim’s systems and disrupts its functioning.
