Traceback Analysis of WannaCry Ransomware

Since May 12, 2017, WannaCry has spread on a massive scale around the world, causing significant impacts. Therefore, security firms start to analyze and prevent the spread of this ransomware. Technical personnel of NSFOCUS also analyzed the sample immediately and released a detailed analysis report.

Analysis Report on the WannaCry Sample
