Title: Record DDoS Pummels Site With Once-Unimaginable 7.3Tbps of Junk
Traffic

An anonymous reader quotes a report from Ars Technica: Large-scale attacks
designed to bring down Internet services by sending them more traffic than
they can process keep getting bigger, with the largest one yet, measured at
7.3 terabits per second, being reported Friday by Internet security and
performance provider Cloudflare. The 7.3Tbps attack amounted to 37.4
terabytes of junk traffic that hit the target in just 45 seconds. That's an
almost incomprehensible amount of data, equivalent to more than 9,300 full-
length HD movies or 7,500 hours of HD streaming content in well under a
minute. Cloudflare said the attackers "carpet bombed" an average of nearly
22,000 destination ports of a single IP address belonging to the target,
identified only as a Cloudflare customer. A total of 34,500 ports were
targeted, indicating the thoroughness and well-engineered nature of the
attack. [...] Cloudflare said the record DDoS exploited various reflection or
amplification vectors, including the previously mentioned Network Time
Protocol; the Quote of the Day Protocol, which listens on UDP port 17 and
responds with a short quote or message; the Echo Protocol, which responds
with the same data it receives; and Portmapper services used identify
resources available to applications connecting through the Remote Procedure
Call. Cloudflare said the attack was also delivered through one or more Mirai-
based botnets. Such botnets are typically made up of home and small office
routers, web cameras, and other Internet of Things devices that have been
compromised.
