A flaw in a popular Wi-Fi security protocol has been discovered that could allow hackers to eavesdrop on your network traffic and even inject ransomware or other malicious content into a website you may be visiting.

The WPA2 protocol, meant to protect both wireless networks and devices, has been compromised by “KRACK” – short for Key Reinstallation Attack. KRACK exploits the protocol flaw to decrypt sensitive data such as credit card numbers, passwords, chat messages, emails, and images. It may affect devices running macOS, Windows, iOS, Android, and Linux.

OS providers and Wi-Fi device manufacturers are already addressing the problem by issuing patches. Those who apply the updates, or have automatic updates enabled, are protected from KRACK. Those who put off running patches will remain vulnerable to attack until corrective action is taken.
