The newly discovered malware known as "Olympic Destroyer" was specifically designed to attack the Olympics, researchers have found, although the first batch of investigations haven't been able to pin point the source.

How it works: Like the name suggests, Destroyer is purely destructive. Unlike ransomware, it does not extort money, and the malware doesn't steal files. Instead, it deletes backup files on a system and tampers with files needed to boot a computer, making it impossible to boot without repair. It does not delete the main files or programs on a computer.
