RESTON, VA – October 21, 2021 – Area identify system (DNS) assaults are impacting organizations at worrisome charges. In response to a brand new survey from the Neustar Worldwide Safety Council (NISC) performed in September 2021, 72% of research members reported experiencing a DNS assault inside the final 12 months. Amongst these focused, 61% have seen a number of assaults and 11% mentioned they’ve been victimized usually. Whereas one-third of respondents recovered inside minutes, 58% noticed their companies disrupted for greater than an hour, and 14% took a number of hours to get better.
DNS assaults are nothing new, they usually are inclined to fall additional down the record of menace considerations. Ransomware, distributed denial-of-service (DDoS) and focused hacking of accounts have rounded out the highest three perceived threats by NISC survey respondents for the six months starting March 2021. Nevertheless, DNS assaults seem like on a gradual upward trajectory. In its October 2020 survey, NISC discovered that 47% of respondents felt DNS compromise was an growing menace; that quantity has risen slowly however steadily over the previous 12 months and now stands at 55% within the newest launch.
In response to the NISC survey, 92% of organizations report that their web site is significant to enterprise continuity and buyer fulfilment at some degree, with 16% solely enabled by it.

“Organizations are challenged to maintain tempo with rising safety threats in an more and more borderless digital panorama. Though some assault vectors will not be as seen or pose as imminent a menace as others, it’s clear dangerous actors will exploit any vulnerability they’ll discover sooner moderately than later, and they’re going to value organizations beneficial time, sources and enterprise,” mentioned Michael Kaczmarek, vp of product administration for Neustar Safety Options. “To handle DNS safety, organizations have to constantly analyze the DNS visitors leaving their group, be sure that they keep good hygiene and entry controls for DNS associated accounts, and, most significantly, implement DNSSEC.”
Cyber criminals seem like sustaining a diversified strategy to their assaults. Though no single vector stands out as a popular technique, the prevalence of a number of ways offers organizations some perception to the place they might want to show their consideration and fortify safety protocols. As an example, almost half of respondents (47%) skilled DNS hijacking and almost the identical proportion (46%) encountered DNS flood, reflection or amplification assaults that segued into DDoS, a chief safety concern. Roughly one-third of members fell sufferer to DNS tunnelling (35%) and to cache poisoning (33%).
“DNS assaults could not seize headlines like an enormous DDoS or ransomware assault does, however the enterprise affect can’t be ignored and their capability to be ignored makes them that rather more harmful,” continued Kaczmarek. “The most recent knowledge signifies that organizations want to stay vigilant, shut safety gaps, and patrol for potential breaches across the clock.”
