TechDad Security Brief: KRAck WiFi Vulnerability

What is the KRAck Attack & What Should I Do About It?

We recently learned about a major vulnerability in the WiFi hardware devices that are already in our homes and offices. This is an important warning that shouldn’t be ignored. TechDad is aware and ready to help you. This vulnerability can potentially expose your personal internet traffic or allow harmful / unwelcome traffic into your personal network. Networks in densely populated areas such as apartment buildings and offices are especially at risk because of how many people are in close proximity. Retail businesses and people who live on a low floors or in private townhouses are vulnerable to hackers who can access their networks from street level. If you are concerned about this, step outside of your home with your wireless device and test to see if you can surf the web on your home network. If you can, you may want to take immediate action.

Hardware vendors have known about this vulnerability since July and have already started preparing updates and patches that can restore your security. Check with your vendor by doing a google search for the make and model of your devices that connect to or provide WiFi. If possible, download and install any available software and firmware updates. Please ensure that you only download updates from the official manufacturer's website because  many hackers will be looking to exploit innocent users.

Affected devices include:

  • Desktops & Laptops

  • Smart Phones

  • Smart TVs

  • Printers

  • Airports & Routers

  • Network Attached Hard Drives

  • IP Security Cameras

  • Smart Home Devices (Alexa, Google Home, Nest, Ecobee, etc...)

Simple Protective Measures To Take Right Now:

Use a wired ethernet connection for your devices that offer it until you have updated the wireless hardware.

Consider disconnecting wireless devices until they can be patched.

If wireless browsing is absolutely necessary before you are able to install patches, use the encrypted versions of popular web browsers with this tool: HTTPS Everywhere (works with Firefox, Chrome, Opera, & Android).
