Today, cybercrime is estimated to cost around $300 billion a year – twice the amount of the drugs economy. It's not just about countries using cyberspace to attack each other, but hackers attacking unsuspecting victims in their homes. Philippe Trouchaud, the author of a book tackling this issue, explains how we, as civilians, can behave to avoid being targeted.
