If you've recently built a Wi-Fi spy camera out of an ESP32-CAM, you can use it for a variety of things. A baby monitor at night, a security camera for catching package thieves, a hidden video streamer to catch someone going somewhere they shouldn't be — you could use it for p ...more
The Raspberry Pi is a credit card-sized computer that can crack Wi-Fi, clone key cards, break into laptops, and even clone an existing Wi-Fi network to trick users into connecting to the Pi instead. It can jam Wi-Fi for blocks, track cell phones, listen in on police scanners, ...more
Due to weaknesses in the way Wi-Fi works, it's extremely easy to disrupt most Wi-Fi networks using tools that forge deauthentication packets. The ease with which these common tools can jam networks is only matched by how simple they are to detect for anyone listening for them. ...more
If you're using a mobile device, it's a pretty safe bet that your apps are sending lots of information back and forth from their servers. To make sure there is no inappropriate data collection going on, it's worth setting up a web proxy to spy on this traffic, so you know exac ...more
Hackers rely on good data to be able to pull off an attack, and reconnaissance is the stage of the hack in which they must learn as much as they can to devise a plan of action. Technical details are a critical component of this picture, and with OSINT tools like Maltego, a sin ...more
Barrow's article on Pupy made me wish for a RAT that could target an OS frequently used by gatekeepers at startups, tech companies, and creative firms: macOS. Once run, a RAT can do severe damage by dumping a user's stored credentials for many accounts. The best loot lives in ...more
When you don't have a steady cellular signal or immediate Wi-Fi access but need to communicate with others around you, you can set up an off-the-grid voice communications network using a Raspberry Pi and an Android app. There are apps such as Bridgefy that will create a mesh ...more
