IoC Report Exposing an Active WannaCry Ransomware Domain Portfolio

WannaCry ransomware made waves as part of a global cyber attack detected in 2017, which resulted in around US$4 billion1 in financial losses. The ransomware campaign targeted organizations in various industries, including the telecommunications, airline, and medical services sectors.

As a self-replicating malware that exploits a vulnerability in Windows, WannaCry has become notorious. The ransomware was last seen in August 20212, still making the identification of WannaCry ransomware-related properties critical.

Over the years, hundreds of WannaCry IoCs have been released by different security experts. WhoisXML API DNS Threat Researcher Dancho Danchev analyzed some of the publicly available IoCs to obtain actionable threat intelligence that can help organizations reinforce their cybersecurity posture.
