Why 'one false click' lets hackers in
Many users of the internet think that by not replying to 'phishing scams' - false invitations encouraging you to hand over personal information - they are safe online.

This is the second video in a series about penetration testers - in the first, LJ Rich learned how hackers can get control of webcams.
