What is Krack?

Most Wi-Fi networks are set up so that someone from outside of the network cannot read or interfere with communications taking place within the network, and essentially hack it. 

WPA2 is one protocol that can be used for this purpose. However, Krack is a vulnerability within WPA2 that could allow an attacker to hack into the network and in some cases, send traffic back to the network. In order for this occur, the attacker must be within range of your device and the Wi-Fi network you’re connected to.

To keep your device secure:

  • Install device updates regularly: Until you have patched your system software, your device will remain vulnerable to an attack.
  • Secure your home Wi-Fi: Keep your internet modem or wireless access point up to date.
  • Encrypt sensitive data between your device and the web (or network services): Do not submit any personal information, including login and password information to a site missing HTTPS
