Shoulder surfing beats security 91% of the time

[ARTICLE] How often do you use your computer in public and forget that people around you can still view your screen? Even in your office, this “over-the-shoulder” attack can be very effective. The 3M company conducted an experiment where they sent out white hat hackers in the guise of temporary office workers. The temps were wearing valid ID badges and were asked to walk through dozens of offices to scout for information, steal confidential documents off random desks, and take pictures with their phones of confidential information on PC monitors. Sadly, in 91% of the situations, these tasks were successful in collecting more than 600 pieces of content. Why 3M? Well, they make privacy screens to help limit the field of view.  -- INFOSECURITY MAGAZINE (summary from Inside Security)
