SANTA CLARA, CA--(Marketwired - June 01, 2016) - Infoblox Inc. (BLOX), the network control company, today released the Infoblox DNS Threat Index for the first quarter of 2016, highlighting a 35-fold increase in newly observed ransomware domains from the fourth quarter of 2015. This dramatic uptick helped propel the overall threat index, which measures creation of malicious Domain Name System (DNS) infrastructure including malware, exploit kits, phishing, and other threats, to its highest level ever.

Ransomware is a relatively brazen attack where a malware infection is used to seize data by encrypting it, and then payment is demanded for the decryption key. According to Rod Rasmussen, vice president of cybersecurity at Infoblox, "There has been a seismic shift in the ransomware threat, expanding from a few actors pulling off limited, small-dollar heists targeting consumers to industrial-scale, big-money attacks on all sizes and manner of organizations, including major enterprises. The threat index shows cybercriminals rushing to take advantage of this opportunity."

The FBI recently revealed that ransomware victims in the United States reported costs of $209 million in the first quarter of 2016, compared to $24 million for all of 2015. High-profile Q1 ransomware incidents include the February 2016 attack on Hollywood Presbyterian Medical Center in Los Angeles and the March 2016 breach at MedStar Health in Washington D.C.

Record Number of New Malicious Domains

The Infoblox DNS Threat Index hit an all-time high of 137 in Q1 2016, rising 7 percent from an already elevated level of 128 in the prior quarter, and topping the previous record of 133 established in Q2 2015. The Infoblox DNS Threat Index tracks the creation of malicious DNS infrastructure, through both registration of new domains and hijacking of previously legitimate domains or hosts. The baseline for the index is 100, which is the average for creation of DNS-based threat infrastructure during the eight quarters of 2013 and 2014.

Five New Countries Top List of Those Hosting Malicious Domains

The United States continues to be the top host for newly created or exploited malicious domains, accounting for 41 percent of the observations, a significant drop from last quarter's 72 percent lion's share. Five other countries and regions saw major increases in activities:

  • Portugal-17 percent

  • Russian Federation-12 percent

  • Netherlands-10 percent

  • United Kingdom-8 percent

  • Iceland-6 percent

Germany, which last quarter accounted for almost 20 percent of newly observed malicious domains and related infrastructure, nearly dropped off the list at less than 2 percent.
