WiFi Alliance Announces Upcoming Fixes to WPA2

Last October, before Intel’s Management Engine was completely broken and the Spectre and Meltdown exploits drove Intel’s security profile further into the ground, we had a problem with wireless networking. WPA2 was cracked with KRACK, the Key Reinstallation Attack. The sky isn’t falling quite yet, but the fact remains that the best WiFi security currently available isn’t very secure at all.

This week, at the Consumer Electronics Show in Las Vegas, the WiFi Alliance announced they would introduce security enhancements in 2018. While it’s not said in the press release if this is a reaction to …read more http://pje.fyi/Q9ftYH

Oh Great, WPA2 Is Broken

WPA2, the standard security for Wi-Fi networks these days, has been cracked due to a flaw in the protocol. Implications stemming from this crack range from decrypting Wi-Fi, hijacking connections, and injecting content. It’s fair to say, WPA2 is now Considered Harmful. The paper is available here (PDF).

This is a proof-of-concept exploit, and like all headline-making network security stories, it has a name. It’s called KRACK, for Key Reinstallation Attack. The key insight to this exploit is a vulnerability in the handshaking between routers and devices to establish a secure connection.

This is not …read more http://pje.fyi/PvwPxg

Hackaday Prize Entry: Don’t Build This

The ESP8266 is a remarkable piece of hardware. What we originally thought — and what was originally marketed as — a simple UART to WiFi bridge with Hayes modem commands has turned into one of the best embedded platforms around. It’s a powerful little microcontroller, it has WiFi, and it can send raw frames. That last bit is awesome, because it allows for some mischief or mirth making, depending on your point of view.

For his Hackaday Prize entry, [Tejas] is building a WiFi Jammer with an ESP8266. It’s a small device that is able to disconnect anyone from a …read more http://pje.fyi/PZ2jWC

ESP32 Mini Robot Packs Sensors and 4WD

[Stefan]’s Mini WiFi/BLE 4WD robot platform (seen next to a matchbox above) packs an impressive capability into a tiny rover. It’s based on a SparkFun ESP32 Thing, a very compact way to add wireless control to your project. Compare it to some giant old UNO with a WiFi shield, these boards are small but powerful, as well as an easy adoption for Arduino fans.

[Stefan] beefed up the robot with a BNO055 module to determine orientation, an APDS-9930 proximity sensor, as well as four CNY70 IR proximity sensors on the bottom, used for line-following. A pair of 6 V motors …read more http://pje.fyi/PN8mw2
