China-Linked Hackers Target Asian Governments, NATO State, Journalists, and Activists

Cybersecurity researchers have disclosed details of a new China-aligned espionage campaign targeting government and defense sectors across South, East, and Southeast Asia, along with one European government belonging to NATO.

Trend Micro has attributed the activity to a threat activity cluster it tracks under the temporary designation SHADOW-EARTH-053. The adversarial collective is assessed to be active since at least December 2024, while sharing some level of network overlap with CL-STA-0049, Earth Alux, and REF7707.

“The group exploits N-day vulnerabilities in internet-facing Microsoft Exchange and Internet Information Services (IIS) servers (e.g., ProxyLogon chain), then deploys web shells (Godzilla) for persistent access and stages ShadowPad implants via DLL sideloading of legitimate signed executables,” security researchers Daniel Lunghi and Lucas Silva said in an analysis.

Targets of the campaigns include Pakistan, Thailand, Malaysia, India, Myanmar, Sri Lanka, and Taiwan. The lone European country that features in the threat actor’s victimology footprint is Poland.

The cybersecurity vendor said it observed nearly half the SHADOW-EARTH-053 targets, particularly those in Malaysia, Sri Lanka, and Myanmar, also compromised earlier by a related intrusion set dubbed SHADOW-EARTH-054, although no evidence of direct operational coordination has been observed.

The starting point of the attacks is the exploitation of known security flaws to breach unpatched systems and drop web shells like Godzilla to facilitate persistent remote access. The web shells function as a delivery vehicle for command execution, enabling reconnaissance and ultimately resulting in the deployment of the ShadowPad backdoor via AnyDesk. The malware is launched using DLL side-loading.

In at least one case, the weaponization of the React2Shell (CVE-2025-55182) is said to have facilitated the distribution of a Linux version of Noodle RAT (aka ANGRYREBEL and Nood RAT). It’s worth mentioning…
