Today, IT security firm ESET® released a useful free tool to help combat the recent ransomware, WannaCry.
ESET’s EternalBlue Vulnerability Checker can be used to determine whether your Windows machine is patched against EternalBlue. This is the exploit behind the WannaCry ransomware epidemic that is still being used to spread cryptocurrency mining software and other malware.
Protecting from EternalBlue is critical. The danger is not in the WannaCry ransomware itself, but in the EternalBlue exploit. This has been using the vulnerability in unpatched Microsoft systems to spread the infection to other unpatched computers. (ESET’s network detection of the EternalBlue exploit, CVE-2017-0144, was added on April 25, prior to the outbreak of the WannaCry threat.

While the WannaCry ransomware remains the most visible, the exploit can still be used in the wild by any other malware – not only ransomware.
