This malware may have been stopped for now, but you never know when another malware comes and exploits this vulnerability. Eset EternalBlue Vulnerability Checker is a free tool that checks if your Windows computer is vulnerable to EternalBlue exploit.
Malware can spread using a vulnerability in implementations of Server Message Block (SMB) in Windows systems. This exploit is named as EternalBlue.
