Serious flaw in WPA2 protocol lets attackers intercept passwords and much more

Researchers have disclosed a serious weakness in the WPA2 protocol that allows attackers within range of vulnerable device or access point to intercept passwords, e-mails, and other data presumed to be encrypted, and in some cases, to inject ransomware or other malicious content into a website a client is visiting. The proof-of-concept exploit is called KRACK, short for Key Reinstallation Attacks.
