Do you run a WiFi network? What is the nature of your business, is it financial? Those could be repackaged Pineapple devices, who knows. http://hakshop.myshopify.com/products/wifi-pineapple?variant=81044992 What about the person? Age? Fit? Could it have been an undercover LEO? Someone doing pentesting seems likely to me. At 04:12 AM 3/19/2015, Troy Etulain wrote:

It would be helpful to know what the units of measurement are on the side. If they are amps it would indicate that the boxes are transmitting a signal, rather than listening. Can you tell from the video?Â

Were the lights flashing? Interesting that only one is illuminated in this photo.Â

We had someone loitering near our front office door today. The conversation went like this:

 Me: What are you doing?  Him: Nothing  Me: Where are you from?  Him: A company  Me: Do you work for Google (he was wearing a Google t-shirt)?  Him: No  Me: Who do you work for?  Him: Leidos

He had a device hidden near the stairwell door:

Sorry for the low quality image. It was taken from a capture of a video. I've got the video at work but would rather not release it as yet because it has his face on it.

The diameter of the antenna base was around 2cm and the height of the antenna was around 15cm.

Someone on Reddit said that it looked like a jammer. After going to Google Images and searching for the following, it looks like he's on the right track:

 - "GSM detector"  - "GSM jammer"  - "GPS detector"  - "GPS jammer"

If anyone has info on what this device could be or where I could go to get more info, that would be much appreciated.
