WannaCry Fact Sheet

Herjavec Group published its first threat advisory on the WannaCry attack on Friday May 12th. In response to WannaCry, Herjavec Group’s Security Operations Centers immediately heightened awareness internally for IOCs, and MD5 hashes which were attributed to the execution and symptoms of the attack. 

Over the 48 hours that followed, HG security engineers developed and deployed rules to all Managed SIEM customers to detect WannaCry IOCs. Alert severities were increased for this threat as the prevalence of media and industry-level knowledge expanded. Senior analysts provided manual coverage until automated rules could be applied.

In the past week, multiple vendors have circulated updates relating to the WannaCry attack. Using recommendations from the latest ISC-CERT communication, Herjavec Group has put together a fact sheet on WannaCry, providing definitions, actions to be taken and recommendations to mitigate ransomware risks.
