Vulnerable systems throughout Asia are being targeted by the newest version of the NRSMiner cryptocurrency malware using the EternalBlue exploit kit. Vietnam specifically is being hit hard by the malware and there are two ways it’s happening. One of the ways the new version is spreading is through the download of an updater module on systems that had been previously affected by an older version of NRSMiner. “On a system that is already infected with an older version of NRSMiner, the malware will delete all components of its older version before infecting it with the newer one. To remove the prior version of itself, the newest version refers to a list of services, tasks and files to be deleted that can be found as strings in the snmpstorsrv.dll file; to remove all older versions, it refers to a list that is found in the MarsTraceDiagnostics.xml file,” said researchers. The second way the malware spreads itself is through unpatched systems. TCP port 445 is scanned by Wininit.exe for systems that are accessible. If the system is exploited successfully, EternalBlue exploits the vulnerabilities.
