Chinese Threat Groups

A recent report released by the Natto Team, a renowned group specializing in geopolitical analysis and cyber threat intelligence, provides a comprehensive overview of the evolving landscape of ransomware deployment by Chinese threat actors. The report delves into the intricate motivations and tactics behind these attacks, emphasizing the increasing convergence of cybercrime and state-sponsored espionage.

The report highlights the blurring lines between financially driven criminal activities and politically charged nation-state operations. As the authors note, “Some cybercrime operations mix state and criminal cyber threat activity,” citing instances such as North Korean state-sponsored actors engaging in cryptocurrency theft to generate illicit revenue. This ambiguity is exacerbated by the complexity and fluidity of the cybercriminal ecosystem, which features a “thriving market in hackers-for-hire and ransomware-as-a-service,” enabling individuals with varying levels of technical expertise to participate in malicious activities.

The Natto Team’s analysis reveals a significant escalation in ransomware deployment by Chinese threat actors since 2016, with a predominant focus on achieving political objectives. These actors utilize ransomware as a multi-faceted tool to:

  • Obfuscate Attribution: Concealing their true origins and intentions.
  • Engineer Distractions: Diverting attention from concurrent malicious operations.
  • Disrupt and Destroy: Inflicting operational disruptions or causing damage to critical infrastructure.
  • Generate Revenue: Securing funds to support further malicious activities.
  • Mask Espionage Operations: Providing cover for the exfiltration of sensitive data.
  • Eliminate Evidence: Destroying traces of their presence within a compromised network.

The report meticulously examines several high-profile cases of ransomware activity attributed to Chinese threat groups:

  • 2016 Codoso: This group, suspected of links to the Chinese government, exhibited a pattern of exploiting vulnerabilities and establishing persistent access long before deploying ransomware, often waiting years to execute the final stage of their attack.
  • 2019 APT41: Known for conducting both state-sponsored espionage and financially motivated cybercrime, APT41 attempted to extort a game company with ransomware after failing to monetize in-game currency.
  • 2020 Winnti Group: This group carried out destructive ransomware attacks against organizations in Taiwan, underscoring China’s tendency to utilize Taiwan as a testing ground for cyber operations.
  • 2022 DEV-0401 (BRONZE STARLIGHT): This group employed ransomware as a smokescreen to conceal espionage activities, deploying a variety of ransomware families with short lifespans.
  • 2023 BRONZE STARLIGHT (SLIME34): This group targeted the Southeast Asian gambling industry with politically motivated attacks.
  • 2024 Palau Government Incident: A ransomware attack targeting Palau’s government systems, coinciding with a ceremony commemorating the country’s relationship with the US, was attributed to Chinese state actors.
  • 2024 ChamelGang: This group deployed ransomware and encryptors across various campaigns, motivated by financial gain, disruption, and evidence removal.

Furthermore, the report identifies several non-Chinese ransomware groups utilizing Chinese names, potentially for misattribution or as an homage to Chinese culture. These groups, often linked to Russia, contribute to the complexity of attribution efforts.

The Natto Team’s report serves as a critical resource for understanding the evolving tactics of Chinese threat actors and their strategic use of ransomware in pursuit of political objectives. It emphasizes the urgent need for enhanced vigilance, proactive threat intelligence, and robust cybersecurity defenses to mitigate this growing threat.
