UNRELATED COMPLAINT SOMEBODY ON THE INTERNET IS WRONG

• People get USB sticks all the time. The problem isn't that people are idiots, that they should know that a USB stick found on the street is automatically bad and a USB stick given away at a trade show is automatically good. The problem is that the OS trusts random USB sticks. The problem is that the OS will automatically run a program that can install malware from a USB stick. The problem is that it isn't safe to plug a USB stick into a computer. Bruce Schneier


People are Idiots

• 20 government agencies

• 70%+ hit rate

• Some sticks phoned home from multiple ‘sensitive’ networks
