It could allow attackers to access private data flowing through an encrypted WiFi network. The data could include usernames, passwords, credit card details, emails, and more.

“There’s a vulnerability in all current implementations of WiFi—the way WiFi works between devices and wireless access points,” says Bob Rudis, chief data scientist at Rapid7, a cybersecurity firm that has already written extensively about KRACK.
