Many digital trees have died for the cause of informing Windows admins about the SMBv1 vulnerability that spawned the WannaCry and ExPetr/NotPetya malware attacks. Yet a relatively small sample of data collected from a freely available tool shows that thousands have not gotten the message, or have some significant blind spots in their networks.
“There are always blind spots,” said Elad Erez, director of innovation at Imperva, who built the scanner called EternalBlues. “If you have 10,000 computers, can you really be that sure (that all hosts are patched)? You can’t. You need someone or something to help you with it.”
