China’s cyber threat landscape during 2025–2026 is shaped by sustained inbound targeting from multiple foreign state-sponsored actors, persistent ransomware pressure across high-value sectors, and an expanding foreign intelligence collection mandate against Chinese national assets. Ransomware activity remains competitive and fragmented, with groups such as LockBit, World Leaks, and TheGentlemen leading activity against high-value sectors including telecommunications, energy, IT, and manufacturing, while legacy vulnerabilities continue to drive exploitation at scale. At the same time, China faces inbound threats targeting sensitive national assets, including alleged compromises of time synchronization infrastructure and large-scale dark-web data leak claims affecting public programs and research institutions. Overall, the environment is characterized by systemic infrastructure risk, zero-day operationalization speed, supply chain leverage, and increasing convergence between cyber espionage, strategic disruption capability, and criminal monetization. Fragmented but Persistent Ransomware Pressure: China faces sustained ransomware activity led by LockBit, World Leaks, and TheGentlemen, with no single actor dominating. Telecommunications, energy, IT, and manufacturing remain the most consistently targeted sectors, reflecting their operational centrality and systemic impact potential. Legacy Vulnerabilities Still Driving Exploitation: Older CVEs (2014–2019) continue to generate significant detection volume, demonstrating persistent patching gaps across exposed infrastructure. Simultaneously, rapid weaponization of newly disclosed 2024–2025 vulnerabilities indicate attackers are balancing opportunistic exploitation with zero-day capability. Supply Chain and Managed Service Provider Risk: Targeting patterns indicate deliberate positioning within SaaS providers, MSPs, and third-party technology ecosystems to achieve downstream access into multiple victim environments simultaneously. Inbound Targeting of Chinese National Infrastructure: Alleged compromises affecting national time synchronization infrastructure and other strategic systems highlight systemic, cascading risk potential where disruption could impact finance, telecommunications, energy, and defense sectors. Dark-Web Data Exposure and Criminal Activity: Multiple large-scale breach claims involving public service databases, financial institutions, and research organizations indicate ongoing data monetization activity, though several claims remain unverified.
