The software locks computers and asks for a digital ransom before control is safely returned. These machines are vulnerable (beyond this attack) to the ransomware functionality of this attack and they need to be updated. Until @MalwareTech inadvertently shut down the campaign by registering the domain, the malware would use this as a mechanism to determine if it should run. A major global ransomware attack going by the name of WannaCry was recently short circuited by the registration of a single domain name costing just over $10.

EternalBlue is a SMBv2 exploit that targets various Windows operating systems, including XP and Windows 7, with various iterations of Windows Server 2003 & 2008 also affected. If the attacker receives this code in response, then the SMB exploits can be used as a means to covertly exfiltrate data or install software such as WannaCry. WannaCry, the ransomware virus that spread earlier this year, affected hundreds of thousands of computers worldwide.

This particular malware uses an APC (Asynchronous Procedure Call) to inject a DLL into the user mode process of lsass.exe. Claims of WannaCry being distributed via email may have been an easy mistake to make. The SMB traffic is also clearly visible in the capture. Rather, our research shows this nasty worm was spread via an operation that hunts down vulnerable public facing SMB ports and then uses the alleged NSA-leaked EternalBlue exploit to get on the network and then the (also NSA alleged) DoublePulsar exploit to establish persistence and allow for the installation of the WannaCry Ransomware. Using packet captures, binary files, and content from within the ShadowBrokers dump, Malwarebyte's Adam McNeil suggests that EternalBlue is the original culprit of the ransomware spread.
