This report explores how a ransomware attack might take place and what the impacts would be on governments, businesses, and the insurance sector. In the scenario, the malware enters company networks through a malicious email, which, once opened, encrypts all the data on every device connected to the network. The email is forwarded to all contacts automatically to infect the greatest number of devices. Companies of all sizes and in all sectors are forced to pay a ransom to decrypt their data or to replace their infected devices.
