On October 16, 2017, Belgian security researchers made public their findings that demonstrated fundamental design flaws in WPA2 that could lead to man-in-the-middle (MITM) attacks on wireless networks.

Named KRACKs, or key reinstallation attacks, this technique can theoretically be used by attackers to steal sensitive information from unsuspecting wireless users leveraging these flaws in the WiFi standard. Based on their research, CERT issued a series of CVEs to address this flaw, and most vendors affected have issued patches as of this writing.
