This analysis covers updates to Hangro, North Korea's state VPN and mail product, which operates on infrastructure spanning North Korea, Russia, and China. The July 2026 deployment introduced a new certificate hierarchy with cryptographic anomalies, including signature verification failures. The infrastructure includes network assignments linked to Silibank in Chinese address space and Russian Far East networks. Hangro evolved from a commercial email gateway to a certificate-bound VPN service used by trade representatives. The mail systems support bulk transfers with large message limits and intermittent connectivity features.
