Taiwan Web Servers Breached by UAT-7237 Using Customized Open-Source Hacking Tools

A Chinese-speaking advanced persistent threat (APT) actor has been observed targeting web infrastructure entities in Taiwan using customized versions of open-sourced tools with an aim to establish long-term access within high-value victim environments. The activity has been attributed by Cisco Talos to an activity cluster it tracks as UAT-7237, which is believed to be active since at least 2022.
