Important Security Flaw in Wi-Fi Exposed

If you watch the news lately, you may have heard about the latest discovery related to the WPA2 protocol used in common Wi-Fi signals.

According to Researcher Mathy Vanhoef, the flaw (cleverly referred to as KRACK Hack) allows attackers within range of a vulnerable device or access point to intercept passwords, e-mails, and other data presumed to be encrypted, and in some cases, to inject ransomware or other malicious content into a website a client is visiting.

The good news is that manufacturers are already distributing software updates to address this vulnerability in laptops, smartphones, and internet routers.

However, until you know that a network is secure, take the necessary precautions when using your connected devices.

  • Use a wired ethernet connection on your network
  • Avoid connecting to public Wi-Fi networks, if possible
  • Avoid visiting sites where sensitive information is stored when connected to a public Wi-Fi network
  • Look for an indication that the website you are visiting has https encryption
  • Use a personal VPN when using a Wi-Fi connection you don’t own, manage or trust
