VERY IMPORTANT

More than a year after the world first saw the Eternal Blue exploit in action during the May 2017 WannaCry outbreak, we are still seeing unpatched machines in Asia being infected by malware that uses the exploit to spread. Starting in mid-November 2018, our telemetry reports indicate that the newest version of the NRSMiner cryptominer, which uses the Eternal Blue exploit to propagate to vulnerable systems within a local network, is actively spreading in Asia. Most of the infected systems seen are in Vietnam.
