Hi @kyssling
Based on our investigation so far, a small subset of Zyxel security appliances is targeted. Currently we haven’t observed any direct correlation with specific firmware versions. The most effective way is to check if there is any unknown SSL VPN user account, such as “zyxel_sllvpn”, “zyxel_ts”, or “zyxel_vpn_test”, has been created. If not, your device is not affected, and please follow the mitigations below as a precaution.0
