RiskIQ’s Q1 2018 Phishing Roundup and 2017 Recap: Phishing Declines, but Targets Increase


June 7, 2018, Andrew Geiger

Phishing actors are always innovating and creating new methods to lure victims into gaining access to their financial information, PII, and user accounts. Understanding the latest phishing techniques and threat actor tendencies helps us position our customers to stay one step ahead of phishing threats targeting their organizations.

The first 2018 quarterly iteration of the Phishing Roundup will detail the trends in phishing activity as observed by RiskIQ over Q1 of 2018, drawing upon data used in the Q4 Report of 2017 for comparison and recapping trends we’ve seen entering into the new year. The data in this report, which is comprised of internally blacklisted resources—unique phishing URLs in this case—will focus on:

  • Threat volume
  • The most targeted brands
  • The WHOIS characteristics of these phishing threats
More Diversity in Targets

For the second quarter in a row, Q1 saw a slight decrease of over 2% in overall phishing detections from Q4 of 2017, with 26,671 unique domains identified. The data we observed, however, was much richer than in the past regarding targeted brands. During Q1, RiskIQ saw a total of 299 unique brands targeted through phishing pages, up from the 259 brands we observed in Q4 of 2017. The category breakdown of the top-ten  targeted brands is as follows:

-40% financial institutions

-20% digital transaction providers

-10% large tech company

-10% major health insurance provider

-10% cloud storage provider

-10% social media platform

As usual, the same financial institutions make up a significant portion of the top-ten targeted brands for Q1 of 2018 and much of the social media targeting trend that we observed in Q4 of 2017 is now mostly gone, which may indicate a return to tried and trusted tactics by threat actors.

However, the top-ten percentage breakdown for Q1, which includes the arrival of cloud storage providers which were not there last quarter, may indicate an overall more diverse detection of targeted brands. This diversity of targets helps RiskIQ’s detection models improve their ability to detect phishing attacks.

Detections by Registrar

Hostinger proved to be a flash in the pan in Q4 2017, leading the list of registrars used by phishing URLs and then dropping out of the top-five entirely. GoDaddy, which is no stranger to the top of this list, reclaimed its place ahead of the pack, which isn’t surprising as phishing attacks, as well as the infrastructure used therein, tend to be extremely cyclical.

Detections by Hosting Provider

The list of top hosting providers used by phishing actors in Q1 was more tumultuous, with all five spots changing hands and three of the five new to the list. Phishing actors are constantly changing infrastructure, so they have shopped elsewhere in Q1 rather than using the same tools from Q4.
