Almost 100 speed cameras in the Australian state of Victoria were unwittingly infected with WannaCry ransomware starting June 6. Authorities have temporarily withdrawn all speed tickets issued since the infection day. The malware on the traffic systems was not the result of a cyber attack; instead, a worker doing maintenance connected a USB stick infected with the malware to the devices. The infection was contained within each unit, not connected to the internet or to each other, and the malware was an earlier version without a so-called kill switch. Until the investigation is finished, all speed notices will be on hold.”]
