Honda forced to temporarily shut down its car plant in Sayama, Japan, after some of its computer systems were infected with the infamous WannaCry ransomware. The incident is particularly strange and worrisome, as the original version of the virus has been stopped from making new victims. Cyber-security experts specialized in ransomware infections have not reported seeing new versions of the malware. This means someone at Honda blocked access to the killswitch domain, allowing the infection to spread, or it means there’s a new version of Wanna Cry going around that doesn’t feature a killswitch.
