WannaCry 2.0 ransomware just arrives with no kill switch

(HackerNews) If you are following the news, by now you might be aware that a security researcher has activated a �Kill Switch� to stop WannaCry ransomware from spreading further, but it�s not over, criminals have just launched WannaCry 2.0 with no �kill-switch� functionality.

WannaCry has already infected over 200,000 computers across 99 countries worldwide only in past two days, and now this latest version can take over other hundreds of thousands of unpatched computers without any disruption.

For those unaware, WannaCry is an insanely fast-spreading ransomware malware that leverages a Windows SMB exploit to target a computer running on unpatched or unsupported versions of Windows and servers and then spread itself like a worm to infect other vulnerable systems in the internal network.
