North Korean operators are presented as repeatedly exploiting Hancom Hangul Word Processor files because HWP is deeply embedded across South Korean government, military, critical industry, defense-contractor, and academic workflows. The article cites malicious HWP spearphishing using embedded PostScript/EPS content to install ROKRAT, CVE-2015-6585 exploitation for remote code execution, Hancom parser flaws, CVE-2020-7882, CVE-2022-33896, and Korean-language lure campaigns. DPRK-linked actors named in the excerpt include APT37/ScarCruft and Kimsuky, with targets including South Korean think tanks, defense researchers, journalists, academics, policy institutes, public-sector users, and alliance-linked supply chains. The risk matters beyond local endpoint compromise because exploitable HWP documents could affect joint US-ROK planning, defense industrial exchanges, operational trust, and potentially wider Indo-Pacific contingency readiness. The recommended mitigations emphasize format hardening, sandboxing or disabling risky EPS behavior, content disarm and reconstruction, convert-before-open workflows, fast Hancom patch SLAs, and shared US-ROK document-security standards.
