Put that back!

Little kids want to put everything in their mouths. We adults often tell them things like "spit that out - you don't know where it's been!"

Alas, similar logic applies to flash drives:

according to a recent Secure Network Technologies Inc. audit of a client credit union, 100% of the trojan-laden, password-collecting, network-compromising USB flash drives they planted outside the client's building were unwittingly plugged in, used, and infected their respective host machines.
