Chinese cyber-espionage groups (APT41, Kelp, Space Pirates) executed a sophisticated, multi-stage intrusion targeting a U.S. non-profit tied to international policy-making. The attack began with mass vulnerability scans (April 5, 2025) exploiting CVE-2022-26134 (Atlassian), CVE-2021-44228 (Log4j), and others, followed by persistent network reconnaissance (April 16) via tools like netstat and schtasks. Attackers abused legitimate utilities (MSBuild.exe, csc.exe, vetysafe.exe) for DLL sideloading, deploying malicious payloads (sbamres.dll) and establishing C2 connections. Techniques included Dcsync for credential theft, enabling privilege escalation and lateral movement. The campaign reflected high operational coordination among Chinese APTs, leveraging shared tooling (e.g., Imjpuexc) to evade detection. The breach aimed at long-term espionage, intelligence exfiltration, and strategic influence, aligning with China’s geopolitical objectives. While no explicit data theft was confirmed, the compromise of a policy-focused organization risks exposure of sensitive diplomatic communications, internal strategies, or stakeholder data potentially undermining U.S. policy formulation and international trust. The use of system-level privileges and persistence mechanisms suggests preparation for prolonged, undetected access.
