Domain Name System Is a Target for Hackers

The mission-critical Domain Name System (DNS) is increasingly a target of more creative cyber- attacks designed to cause downtime or damage, according to a new study. Attackers use the DNS to exfiltrate data or launch distributed-denial-of-service attacks, according to the 2017 "Global DNS Threat Survey," conducted by Coleman Parkes for EfficientIP. DDoS attacks are the second highest DNS-related attack type (32 percent) after malware (35 percent). In third place is Cache Poisoning (23 percent), followed by DNS Tunneling (22 percent) and Zero-Day exploits (19 percent). Yearly average costs of damages caused by DNS attacks are $2.2 million, and 76 percent of organizations have been victimized during the past 12 months (up 2 percent since last year), the report revealed. "Organizations must ensure they have the right solution in place to prevent business damage, such as a loss of sensitive information, downtime or compromised public image," said David Williamson, CEO of EfficientIP. The survey included 1,000 respondents, including 300 from North America, 400 from Europe and 300 from APAC. The survey's goal was to examine the technical and behavioral causes for the rise in DNS threats and the potential business effects, and to suggest straightforward, rapid remedies.
