For past DTLS-based DDoS attacks, the amplification factor was usually 4 or 5 times the original packet.<\/p>\n<p>But, on Monday, Hofmann reported that the DTLS implementation on Citrix ADC devices appears to be yielding a whopping 35, making it one of the most potent DDoS amplification vectors.<\/p>\n<h3>Citrix confirms issue<\/h3>\n<p>Earlier today, after several reports, Citrix has also&nbsp;<a href=\"https:\/\/support.citrix.com\/article\/CTX289674\" target=\"_blank\" rel=\"noopener noreferrer nofollow\" data-component=\"externalLink\">confirmed the issue<\/a>&nbsp;and promised to release a fix after the winter holidays, in mid-January 2020.<\/p>\n<p>The company said it&#8217;s seen the DDoS attack vector being abused against &#8220;a small number of customers around the world.&#8221;<\/p>\n<p>The issue is considered dangerous for IT administrators, for costs and uptime-related issues rather than the security of their devices.<\/p>\n<p>As attackers abuse a Citrix ADC device, they might end up exhausting its upstream bandwidth, creating additional costs and blocking legitimate activity from the ADC.<\/p>\n<p>Until Citrix readies officials mitigations, two temporary fixes have emerged.<\/p>\n<p>The first is to disable the Citrix ADC DTLS interface if not used.&nbsp;<\/p>\n<figure class=\"media-source\">\n<div class=\"twitterContainer\" readability=\"7.5229885057471\">\n<blockquote class=\"twitter-tweet\" readability=\"8.8505747126437\">\n<p lang=\"en\" dir=\"ltr\">Citrix ADC<\/p>\n<p>If you&nbsp;are impacted by this attack&nbsp;you can&nbsp;disable DTLS&nbsp;to stop it.
