Why did this happen?
Your WiFi connection is vulnerable to a Key Reinstallation AttaCK (KRACK).
What is Key Reinstallation AttaCK?
A Key Reinstallation AttaCK (KRACK) vulnerability allows attackers within range of vulnerable Wi-Fi enabled devices or access points to intercept passwords, messages, and other data.
What are its risks?
Attackers could steal information such as account credentials, messages, and confidential information.
