A Canadian company has helped dismantle a massive computer-infiltration ring that infected more than 15 million computers around the world – including systems within Canadian banks and the federal government.

Spanish police have arrested three people charged with running a botnet – a program that infects and partly takes over victims’ computers – that spanned some 190 countries. Not only is the botnet (named Mariposa, Spanish for butterfly) one of the largest of its kind, the software’s operators appeared to target government and corporate computers, stealing huge amounts of sensitive data.
