WiFi Scanner 2.9.2
*Airport Monitor: Attention for users of the latest 2013 Airport edition with 802.11ac: Because SNMP support has been disabled by Apple iNet cannot retrieve the usage statistics and wifi strength anymore with these models. All other features of iNet are working properly. The following Airport monitoring features can only be used with models prior to the 802.11ac:
WiFi Scanner 2.9.2
If you're ever in a situation where you need to take a peek at the wireless spectrum, whether it's for Bluetooth or Wi-Fi devices, there's a fascinating Python 3-based tool called Sparrow-wifi you should check out. It's cross-platform, easy to use, and has an impressive GUI that shows you the signal strength of nearby devices.
Sparrow-wifi, branded as a "next-generation" analysis tool for wireless reconnaissance and surveillance, is simple to install. There's just a bunch of Python libraries you need, and then no matter what system you're on, it should be pretty easy to use. It works great on a Raspberry Pi, and just as good on Kali Linux.
Ghostop14 created Sparrow-wifi to be installed on a Raspberry Pi attached to a drone or rover for war-flying or wardriving use cases. It was even tested out on a 3DR Solo aerial drone, and you can read more about their experience using Sparrow-wifi on Raspberry Pi and drone on the GitHub page. We'll just be using it on a Kali Linux system running on a laptop, but it'll be similar for a Pi-based project.
Before getting into using Sparrow-wifi, it's good to show what all it can do. Being a "next-generation 2.4 GHz and 5 GHz Wifi spectral awareness tool," it has Wi-Fi capabilities, a software-defined radio, advanced Bluetooth options, and GPS capabilities (which can also be connected to the GPS on drones and rovers). The most prominent features worth pointing out today include but aren't limited to:
That last command should open the GUI for Sparrow-wifi. Once it's up, we can select an interface that we want to scan on in the Local Interface drop-down menu. Then, press the "Scan" button next to it.
I'm not actually moving, so you're not going to see a big jump in signal strength in my screenshots, but if you move your directional antenna around and point it in the right direction, you'll see a big spike in strength in the top left pane. You can see spikes like that in our guides on choosing the right antenna for Wi-Fi hacking and hunting down Wi-Fi devices with a directional antenna. But setting up Wireshark is a lot more complicated than just firing up Sparrow-wifi.
Sparrow wifi is a quick and easy way to throw up a GUI interface and see what's around you, whether you're looking for Bluetooth or Wi-Fi devices. Now, it's not exactly as advanced as something like Kismet, which can show you all sorts of detailed information about everything, but it's a really great Python tool to get started. It can even be mounted on a drone, which is pretty impressive.
