... 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
sounds legit ;P
He had a device hidden near the stairwell door:
this is likely automated wifi attack gear. the three units together could cover channels 1, 6, 11 concurrently. (in my own kit, 4-8 radios is sweet spot) the extra battery capacity lets it run for days attacking on full auto. unlikely to be a jammer because they cover more frequencies and this appears tuned to 2.4Ghz. you should be running wireless intrusion (e.g. custom kismet?) monitoring to look for malicious activity. and of course, it is time to change all your WPA2 passwords! (or switch to WPA-Enterprise)
