UAT-10362 is a previously undocumented threat cluster conducting targeted spear-phishing campaigns against Taiwanese NGOs and universities, deploying the novel Lua-based LucidRook malware via DLL side-loading with geofenced payload delivery restricted to Traditional Chinese (zh-TW) environments. No CVE is assigned as this is a malware campaign rather than a patchable software vulnerability; defensive focus should center on DLL side-loading prevention, spear-phishing controls, and detection engineering against T1574.002, T1480.001, and T1614.001. Organizations with Taiwan-facing roles or diaspora community ties face elevated targeting risk.
