System Advisor in Norton Mobile Security displays KRACK vulnerability alert

System Advisor scans your device and alerts about known vulnerabilities such as KRACK, and untrusted certificates if found. It also checks if your device is rooted. If any of these risks are detected, System Advisor helps you with information on how to fix the risks.

Key Reinstallation Attacks (KRACK) vulnerability allows attackers access to important information like credit card numbers, passwords, and any emails that are transmitted over WiFi networks. It also allows attackers to potentially infect your devices with malware or ransomware. For more information on the KRACK vulnerability, read What you need to do about the WPA2 WiFi network vulnerability.

To fix the KRACK vulnerability, make sure that you install all the available firmware and software updates on all of your Wi-Fi enabled devices. For more information, contact your device manufacturer.

We also recommend you to use a VPN service to protect your device when connected to an unsecured Wi-Fi network. Learn more about Norton WiFi Privacy - a VPN solution from Norton.

If you do not want to be notified of this vulnerability again, in the System Advisor alert window for KRACK, tap Ignore to add it to the 'Ignore list'.
