Infrastructure hunting from the Kimsuky-linked seed domain xpo.coupang.dns.navy expanded a single public indicator into a mapped cluster of 43 servers and 664 associated domains. The infrastructure showed repeated use of AS135377/UCloud Information Technology (HK) Limited, similar HTTP and HTML fingerprints, exposed services including RDP and web ports, and recurring Korean-themed phishing or document-service domain patterns. The report assesses moderate-to-high confidence attribution to Kimsuky based on infrastructure overlaps, hosting patterns, fingerprint correlation, and consistency with previously reported DPRK cyber-espionage operations.
