How the Krack Hack Breaks Wi-Fi Security

The video discusses the KRACK vulnerability in Wi-Fi networks, which exploits the WPA2 protocol's four-way handshake, allowing hackers to intercept and decrypt data. Although the vulnerability is significant, it requires physical proximity to the network. Tech companies are working on patches, and users are advised to update their devices. The video also introduces Brilliant.org's logic course.
