While it\u2019s not uncommon for Dyn\u2019s Network Operations Center (NOC) team to mitigate DDoS attacks, it quickly became clear that this attack was different,\u201d said York.<\/p>\n<p>Approximately two hours later, the Dyn NOC team was able to mitigate the attack and restore service to customers.<\/p>\n<p>During that time, Internet users directed to Dyn servers on the East Coast of the US were unable to reach some of Dyn\u2019s customers\u2019 sites, including some of the marquee brands of the Internet.<\/p>\n<p>\u201cWe should note that Dyn did not experience a system-wide outage at any time \u2013 for example, users accessing these sites on the West Coast would have been successful,\u201d said York.<\/p>\n<p>After restoring service, Dyn experienced a second wave of attacks just before noon. This second wave was more global in nature, but was mitigated in just over an hour.<\/p>\n<p>\u201cAgain, at no time was there a network-wide outage, though some customers would have seen extended latency delays during that time,\u201d said York.<\/p>\n<p>\u201cWhile there was a third attack attempted, we were able to successfully mitigate it without customer impact,\u201d he said.<\/p>\n<p>\u201cAt this point we know this was a sophisticated, highly-distributed attack involving 10s of millions of IP addresses,\u201d said York.<\/p>\n<p>He said it was a sophisticated attack across multiple attack vectors and Internet locations, and that one source of the traffic for the attacks was devices infected by the Mirai botnet.<\/p>\n<p>\u201cWe observed 10s of millions of discrete IP addresses associated with the Mirai botnet that were part of the attack,\u201d said York.<\/p>\n<h3 class=\"my-4\">Now read:\u00a0<a href=\"http:\/\/mybroadband.co.za\/news\/internet\/184014-how-a-ddos-attack-took-out-a-huge-part-of-the-internet.html\" target=\"_blank\">How a DDoS attack took out a huge part of the Internet<\/a><\/h3>\n","protected":false},"excerpt":{"rendered":"<p>Dyn\u2019s Chief Strategy Officer has provided details about the DDoS attack which resulted in downtime for prominent websites across the world.<\/p>\n","protected":false},"author":23,"featured_media":160024,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_sma_x_autopost_status":"idle","_sma_x_autopost_error":"","_sma_x_post_id":"","_sma_facebook_post_id":"","_sma_instagram_post_id":"","_sma_threads_post_id":"","_sma_x_attempts":0,"footnotes":""},"categories":[27],"tags":[723,2242,39424,35,39440,169,8045,405],"class_list":["post-184180","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-security","tag-amazon","tag-ddos","tag-dyn","tag-headline","tag-kyle-york","tag-paypal","tag-reddit","tag-twitter"],"_links":{"self":[{"href":"https:\/\/mybroadband.co.za\/news\/wp-json\/wp\/v2\/posts\/184180"}],"collection":[{"href":"https:\/\/mybroadband.co.za\/news\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/mybroadband.co.za\/news\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/mybroadband.co.za\/news\/wp-json\/wp\/v2\/users\/23"}],"replies":[{"embeddable":true,"href":"https:\/\/mybroadband.co.za\/news\/wp-json\/wp\/v2\/comments?post=184180"}],"version-history":[{"count":1,"href":"https:\/\/mybroadband.co.za\/news\/wp-json\/wp\/v2\/posts\/184180\/revisions"}],"predecessor-version":[{"id":184190,"href":"https:\/\/mybroadband.co.za\/news\/wp-json\/wp\/v2\/posts\/184180\/revisions\/184190"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/mybroadband.co.za\/news\/wp-json\/wp\/v2\/media\/160024"}],"wp:attachment":[{"href":"https:\/\/mybroadband.co.za\/news\/wp-json\/wp\/v2\/media?parent=184180"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/mybroadband.co.za\/news\/wp-json\/wp\/v2\/categories?post=184180"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/mybroadband.co.za\/news\/wp-json\/wp\/v2\/tags?post=184180"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
