On October 2017, security vulnerabilities were disclosed in WPA2 (Wi-Fi protected Access II), which made it possible for a user to eavesdrop on Wi-Fi traffic that utilized WPA2. An attacker within the wireless range of a Wi-Fi network can exploit these vulnerabilities using key reinstallation attacks (KRACKs).
Moxa's Cyber Security Response Team (CSRT) is fully engaged in this matter and we are taking appropriate action. Our team has been working with all of our product teams to determine which models have been affected.
