Cisco has released another batch of security updates, the most critical of which fixes a vulnerability that could allow unauthenticated, remote attackers to gain access to vulnerable Cisco Aironet wireless access points. Cisco Aironet APs are enterpris… Continue reading Cisco fixes serious flaws in enterprise-grade Catalyst and Aironet access points
Are you bored of your traditional bow tie? Do you wish it RGB LEDs, WiFi, and a web interface that you could access from your smartphone? If you’re like us at Hackaday…maybe not. But that hasn’t stopped [Stephen Hawes] from creating the Glowtie, an admittedly very slick piece of open …read more

Your Wi-Fi routers and access points all have strong WPA2 passwords, unique SSIDs, the latest firmware updates, and even MAC address filtering. Good job, networking and cybersecurity teams! However, is your network truly protected? TL;DR: NO! In this p… Continue reading No One is Safe: the Five Most Popular Social Engineering Attacks Against Your Company’s Wi-Fi Network
One of the biggest advantages of using the ESP8266 in your projects is how easy it is to get WiFi up and running. Just plug in the WiFi library, put the SSID and encryption key in your source code, and away you go. It authenticates with your network in seconds and you can get on with building your project. But things get a little trickier if you want to take your project someplace else, or distribute your source code to others. Quickly we learn the downside of using static variables for authentication.
While there are already a few solutions to …read more
If you only do projects for yourself, you are spoiled. After all, you know your environment better than anyone. You know what power you’ll have, the temperature range, and how your network is configured. This last part is especially problematic if you are trying to deploy something that connects to a wireless LAN. How can you configure, say, a Raspberry Pi so that it can connect to an unknown user’s WiFi network? Fixing that problem is the goal of [schollz’s] Raspberry Pi Turnkey project.
The idea is simple. A Raspberry Pi image boots up for the first time and offers …read more
WPA2, the most widely used Wi-Fi security standard, has a number of flaws that could allow hackers to snoop on users’ internet traffic or, worse, to inject malware into it. The vulnerabilities are in the protocol itself, more precisely in the four-way handshake between clients and access points. It allows attackers to mount an evil..

The Raspberry Pi Zero W is a great platform for IoT projects, with a smattering of GPIO and onboard WiFi. However, security is an important consideration when it comes to the Internet of Things and it can be beneficial to keep your IoT devices on a separate network for safety’s sake. [Albert] wanted to do this all on board the Pi Zero W, and figured out how to get it acting as an access point and a client all at the same time.
[Albert] starts off with a fresh install of Raspbian Stretch, and sets the Pi up in OTG …read more
There’s no doubt that the ESP8266 has made creating little WiFi widgets pretty easy. However, a lot of projects hard code the access point details into the device. There’s a better way to do it: use the WiFiManager library. [Witnessmenow] has a good tutorial and a two-minute video (which you can see below).
Hard coding is fine if you are just tinkering around. However, if you are going to send your device away (or even take it with you somewhere) you probably don’t want to reprogram it every time you change access points. This problem is even worse if you …read more

Researchers claim that with a modified Wi-Fi access point they can use the radio interference of your fingers to guess your password. Continue reading Wi-Fi shadows cast by your fingers could leak your password
