More than 50,000 computers vulnerable to the NSA-linked EternalBlue exploit were found by a free vulnerability scanner in recent weeks.

Dubbed Eternal Blues, the tool was designed to provide network administrators with visibility into the EternalBlue-vulnerable machines in their networks, but without actually exploiting the flaw. In the wake of WannaCry, NotPetya, and other global infectionsleveraging the NSA-linked exploit, knowing whether a network is vulnerable or not is certainly a good idea.
