About
Distributed Denial of Service (DDoS) is a method of cyberattack that usually involves temporarily blocking access to a website or server by flooding the bandwidth of a targeted network. The most common methods of DDoS include exploiting unprotected server networks, sending massive requests or opening multiple connections with the server.
Origin
The first publicly available DDoS tools Trinoo and Tribe Flood Network were released in 1997 and 1998 respectively.[8] The first well-documented DDoS attack took place in August 1999, which targeted a single University of Minnesota computer and knocked the system offline for more than two days. DDoS came grabbed public’s attention months later in February 2000, after a number of high profile search portals and e-commerce sites were taken offline for hours, including Yahoo!, Amazon, Buy.com, CNN, eBay, E*Trade and ZDNet. In addition, several companies reported significant losses due to the downtime, with Yahoo! losing about $500,000 and costing Amazon nearly $600,000.[7]
Spread
According to The Next Web’s timeline of DDoS attacks[6], most notable attempts in the first half of the 2000s were made by individuals using botnets and software programs. In 2001, Register.com came under a severe attack using tens of thousands of DNS records from around the world that lasted for an entire week.[9] In October 2002, all 13 Domain Name System root nameservers were targeted by a DDoS attack, which lasted for approximately one hour. In 2003, eBay was taken offline by a DDoS attack involving 20,000 computers, causing damage of at least $5,000.[10]
