Security researcher Sarah Jamie Lewis wanted to demonstrate that the horrific stories of insecure networked sex-toys (and other Internet of Things devices) was the result of manufacturers' negligence, not the intrinsic limitations of information security.
So she bough a We-Vibe Nova sex toy and hacked it so that it could take commands over the cryptographically secured Tor anonymity/privacy network, using the Ricochet chat protocol to create an extra layer of security. The demo shows that the security problems with the IoT have more to do with the manufacturers' desire to spy on their customers than the difficulty of getting security right.
Lewis's approach uses Ricochet, a messaging program which creates a Tor hidden service for each user. Ricochet doesn't just protect the content of users' communications, but also obfuscates their metadata, making it harder for anyone snooping on the connection to see who is talking to whom. Lewis reverse-engineered her dildo, a Nova from Canadian company We-Vibe, so she could communicate with it over bluetooth. When combined, these elements allow anyone who knows the dildo's Ricochet address to send commands, such as "/max," to make the device vibrate. Lewis has uploaded the code to Github so others can try the experiment.
Motherboard started a 'chat' session with Lewis' vibe, and sent a series of simple commands. Lewis then sent a video of the dildo vibrating.

The Raspberry Pi Foundation announced a new model in its line of very inexpensive Linux computers: the Raspberry Pi 3 Model A+. It has many of the same features as the top-of-the-line 3B+ (including a 1.4GHz 64-bit quad-core processor, dual-band wireless LAN, and Bluetooth 4.2/BLE), the main exceptions being 512MB of RAM instead of 1GB, […]

There are two times you never want to just “eyeball” it: Conducting brain surgery and matching shades of paint for your walls. Whether you’re painting or repainting, make sure you’re never just “close enough” to the color you want. Not when the Nix Mini Color Sensor can scan and match any color perfectly. Small enough […]
