Wi-Fi Security Flaw Exposes Users to Security Risk

November 6, 2017 | BerganKDV Team

The United States Computer Emergency Readiness Team issued the following warning in response to a recent exploit:

The vulnerabilities are in the WPA2 protocol, not within individual WPA2 implementations, which means that all WPA2 wireless networking may be affected. Mitigations include installing updates to affected products and hosts as they become available.

What does this mean?

Wi-Fi Protected Access II (WPA2) is a protocol that secures all modern protected Wi-Fi networks. An attacker within range of a victim can exploit these weaknesses using key reinstallation attacks (KRACKs). Thus, attackers can use this novel attack technique to essentially eavesdrop on your network traffic. This can be abused to steal sensitive information such as credit card numbers, passwords, chat messages, emails photos and so on. The attack works against all modern protected Wi-Fi networks.

Note that if your device supports Wi-Fi it is most likely affected. To prevent the attack, users must update affected products as soon as security updates become available.
