For those unaware, EternalBlue is a Windows SMB flaw that was leaked by the Shadow Brokers in April and then abused by the WannaCry ransomware to infect nearly 300,000 computers in more than 150 countries within just 72 hours on 12th of May. Shortly after WannaCry outbreak, we reported that three unpatched Windows exploits , codenamed " EsteemAudit, " " ExplodingCan ," and " EnglishmanDentist ," were also being exploited by individuals and state-sponsored hackers in the wild.

Slovakia-based security software maker ESET and US critical infrastructure security firm Dragos Inc. say they have discovered a new dangerous piece of malware in the wild that targets critical industrial control systems and is capable of causing blackouts. Dubbed " Industroyer " or " CrashOverRide ," the grid-sabotaging malware was likely to be used in the December 2016 cyber attack against Ukrainian electric utility Ukrenergo , which the security firms say represents a dangerous advancement in critical infrastructure hacking.
