Huapi
Huapi is a Chinese threat group referenced in reporting on APT activity targeting network edge infrastructure and trusted upstream providers. The provided content states that Huapi, alongside SLIME86, successfully breached upstream providers and then pivoted into downstream government, military, and critical infrastructure networks, reflecting a “Fail-of-Trust Model” in which attackers compromise IT/service providers, managed service vendors, or cloud platforms to inherit access to customer environments. The same reporting places Huapi in the broader context of China-nexus actors targeting firewalls, routers, and VPN appliances by exploiting critical vulnerabilities, using device-family-specific backdoors designed to survive firmware updates and restarts, and leveraging IoT and NAS devices as relay infrastructure, including reverse SSH tunnels, to obscure origins and support data theft. Known alias in the provided content: huapi.
