Exploits revealed in the NSA hacking toolkit leak of late 2016 were used to enable the propagation of the malware.Shortly after the news of the infections broke online, a UK cybersecurity researcher in collaboration with others found and activated a "kill switch" hidden within the ransomware, effectively halting the initial wave of its global propagation.The next day, researchers announced that they had found new variants of the malware without the kill switch.
- June: The Petya (malware) attack spreads globally affecting Windows systems. Researchers at Symantec reveal that this ransomware uses the EternalBlue exploit, similar to the one used in the WannaCry ransomware attack.
