A modified Ghostbusters Proton Pack

Track Down Ghosts In Your WiFi With The Pwnton Pack

If there’s something weird in your Network Neighborhood, who you gonna call? If you want your WiFi troubles diagnosed in style, try calling [Travis Kaun] — he might just show up wearing the amazing Pwnton Pack. Built from a replica Proton Pack similar to those used in the 1984 classic Ghostbusters, it’s a portable wireless security diagnostics kit that should be able to pinpoint any weaknesses in your wireless network.

Inside, it’s got a Mark VII WiFi Pineapple, which is a portable device designed for security testing purposes, as well as a Raspberry Pi running Pwnagotchi: a deep learning-based WiFi sniffer that aims to capture those network packets that help maximize your chances of brute-forcing the WPA key. These two devices are connected to an array of antennas, including a cool rotating 5 GHz panel antenna to scan the surrounding area.

Naturally, the Pwnton Pack also includes a Neutrona Wand, which in this case contains a 2.4 GHz Yagi antenna hooked up to an ESP32 programmed to perform deauthentication attacks. An Arduino Nano drives an LED matrix that shows scrolling Pac-Man ghosts, while a dedicated sound board provides movie sound effects. The whole system is powered by three LiPo battery packs, and can even be remotely operated if desired.

Sadly, it doesn’t come with one of those ghost traps to suck up wayward WiFi networks, but the range of tools available should help to catch any kind of weird phantoms hiding in your system. We’ve spotted a few Proton Packs before, but never one with such advanced functionality. Security testing systems tend to be a bit less conspicuous, after all.

Automated Tools For WiFi Cracking

Knowing how WiFi networks can be attacked is a big part of properly securing them, and the best way to learn about it is to (legally) run some attacks. [Matt Agius] has been going down the WiFi-cracking rabbit hole, and in the process created Pwnagotchi Tools to automate the actual password cracking part.

The first step in cracking a WiFi network is to record the handshake that gets exchanged when a client connects to an access point. This has been made very simple thanks to Pwnagotchi, which turns a Raspberry Pi into an automated handshake collection tool and Pwnagothi Tools helps to automate the steps that follow. It downloads the handshakes (pcap files) from the pwnagotchi, and converts it to pmkid/hccapx files to use with the hashcat password recovery tool. Hashcat scripts can then be generated for the actual cracking using any of the attacks that [Matt] has compiled. WPA/WPA2 is slow to crack and requires a lot of processing power, so [Matt] also added the option to automatically provision AWS GPU instances to run the cracking task in the cloud. It also keeps track of the status of each of the handshakes being cracked.

As wireless networks and IoT devices become more pervasive, it’s important to know the dangers, and how to protect against them. WiFi and Bluetooth security is probably the easiest to learn about, but other networks are just as vulnerable when an RTL-SDR is used. Another option Flipper Zero, a hacking gadget for Sub-1 GHz networks inspired by Pwnagotchi, which recently hit $4.8 million in its Kickstarter campaign.

Screaming Channels Attack RF Security

As long as there has been radio, people have wanted to eavesdrop on radio transmissions. In many cases, it is just a hobby activity like listening to a scanner or monitoring a local repeater. But in some cases, it is spy agencies or cyberhackers. [Giovanni Camurati] and his colleagues have been working on a slightly different way to attack Bluetooth radio communications using a technique that could apply to other radio types, too. The attack relies on the ubiquitous use of mixed-signal ICs to make cheap radios like Bluetooth dongles. They call it “Screaming Channels” and — in a nutshell — it is relying on digital information leaking out on the device’s radio signal.

Does it work? The team claims to have recovered an AES-128 key from 10 meters away. The technique reminds us a bit of TEMPEST in that unintended radio transmissions provide insight into the algorithm the device applies to encrypt or decrypt data. Most (if not all) encryption techniques assume you can’t see inside the “black box.” If you can, then it’s because it is relatively easy to break the code.
