Executive Summary

A newly identified China-aligned cyberespionage campaign tracked as SHADOW-EARTH-053 is targeting government agencies, defense-adjacent contractors, and critical infrastructure organizations across Asia through exploitation of unpatched Microsoft Exchange and IIS vulnerabilities. The operation relies heavily on legacy Exchange flaws, web shell persistence, ShadowPad malware deployment, credential theft, and covert tunneling infrastructure to maintain long-term access within victim environments. The campaign demonstrates that older but still-exploitable enterprise infrastructure continues to provide reliable access opportunities for state-aligned espionage operators and reinforces the operational importance of proactive detection, behavioral monitoring, and layered telemetry visibility.
