An exposed Alibaba Cloud server has revealed a China-nexus operation that Group-IB tracks as JadeProx. The cluster has targeted government, healthcare, and education organizations across Asia and Latin America with a previously undocumented Windows loader called TriBack Loader.
Group-IB found the server in mid-April 2026 in Alibaba Cloud's Singapore region; it was offline by the time the report published on July 23, 2026.
Its bash history, phishing packages, post-exploitation tools, and webshell paths laid the operation out: active intrusions against a Vietnamese public hospital's medical imaging system and Malaysia's Ministry of Foreign Affairs, scanning and exploitation follow-up against Hong Kong education infrastructure, and a spear-phishing package addressed to the National Congress of Honduras.
The operators reached the hospital's imaging server through webshells planted on an exposed Java management interface.
