Sanyo is a China-linked cyber-espionage threat actor reported to have targeted Russian defense-related interests. The group has been described as masquerading as a Russian engineering firm in order to collect information on nuclear submarines, indicating a focus on military and defense intelligence collection through spoofing and social-engineering-style impersonation. Reported activity places Sanyo among Chinese intrusion sets that have targeted Russian state and corporate entities for sensitive military and strategic information following the start of the Russia-Ukraine war. Publicly available information in this context is limited, and no high-confidence aliases, malware families, or sub-groups are established here beyond the name Sanyo itself.
