Murray's TSCM Tip # 623 - Hiding in Plain Sight - The USB Microphone

USB microphones have many legitimate uses, students recording lectures, for example. Much more sensitive than a laptop's built-in microphone, they are perfect for that application. They also make eavesdropping on co-workers very easy.

The Plausible Deniability Bonus... Hey, it's not a bug. It's a legitimate piece of office equipment.

If you see one of these in a laptop, always assume it is recording. Some USB microphones have a red tally light, but a dot of black paint (or a piece of electrical tape) can cripple that tip-off. 

From the seller...
"This microphone is capable of picking up all of the sounds in large room (range of approximately 80 feet) or it can pick up small area its up to you, because you control the amplifier power! It's small size makes it perfect for situations where you don't want to draw attention to the fact that you are recording audio right into your computer."
