While the USB Rubber Ducky is well known by hackers as a tool for quick in-person keystroke injection attacks, one of the original uses for it was automation. In this guide, I'll be going the latter, explaining how we can use it to automate Wi-Fi handshake harvesting on the Ra ...more

The Nintendo Switch and Switch Lite are console gaming on the go — with zero regards for modern audio features. Headphone jack? Check. Bluetooth connectivity? Not so much. While Nintendo seems to think we're all happy to live like it's 2015, there's a way to use your AirPods w ...more

On April 7, 2017, residents in Dallas, Texas, woke to the sound of emergency sirens blaring all over the city. No one could shut them off, and after repeated efforts to contain the situation, the city had to shut down the entire system. While the media reported a sophisticated ...more

Electronic warfare tactics work by jamming, disrupting, or disabling the technology a target uses to perform a critical function, and IoT devices are especially vulnerable to attacks. Wireless security cameras like the Nest Cam are frequently used to secure critical locations, ...more

Smartphones and laptops are constantly sending Wi-Fi radio signals, and many of these signals can be used to track us. In this guide, we'll program a cheap IoT device in Arduino to create hundreds of fake networks with common names; This will cause nearby devices to reveal the ...more

Smartphones and other Wi-Fi enabled devices send radio signals called probe frames to locate nearby wireless networks, which makes them easy to track by listening for their unique MAC address. To show how this kind of tracking works, we can program a NodeMCU in Arduino to snif ...more

Sniffing packets over a network is an easy way for hackers to gather information on a target without needing to do much work. But doing so can be risky if sniffing packets on an untrusted network because a payload within the packets being captured could be executed on your sys ...more
