Chinese Ink Dragon Breaches European Government Networks, Affecting Asia and South America
Ink Dragon, a Chinese cyber-espionage group, has expanded its operations from Southeast Asia and South America into European government networks. This development has been observed through ongoing research by Check Point Research.

The group employs a strategic approach, using server compromises and sophisticated relay infrastructure to maintain persistent access and support global operations. This tactic involves utilizing compromised servers as relay nodes, turning victim organizations into infrastructure for broader espionage activities.
Ink Dragon's approach is characterized by extended dwell times and minimal detection signatures, obscuring command and control traffic while maintaining resilience through distributed communication pathways.
The attack chain usually begins with reconnaissance of public-facing web infrastructure, targeting common configuration weaknesses in Microsoft IIS web servers and SharePoint deployments. These entry points allow initial code execution with minimal visibility, enabling a foothold in target networks.
Once established, the group focuses on lateral movement using legitimate administrative credentials and service accounts. This method allows them to blend with regular enterprise activity, reducing detection probability.

The operation culminates in domain-level access, enabling comprehensive mapping, policy manipulation, and persistent backdoor deployment. This approach prioritizes stealth and sustainability over rapid escalation.
Ink Dragon systematically repurposes compromised environments, deploying customized IIS-based modules that convert servers into relay nodes. This creates a communication mesh that obscures attack traffic origins, presenting it as ordinary activity to security systems.
The relay infrastructure offers operational resilience, natural camouflage within standard HTTP traffic patterns, and extended utility from compromised systems.
The group's toolset continues to evolve, focusing on cloud-aware capabilities. The updated FinalDraft backdoor is optimized to blend into Microsoft cloud activity patterns, disguising communications as routine service usage.
Investigations have revealed concurrent activity by another threat actor, RudePanda, within the same compromised networks. Both groups exploited identical vulnerabilities, highlighting how unpatched weaknesses can attract multiple threat actors.
For cybersecurity professionals, these operations underscore the need to investigate compromised systems as potential communication infrastructure for broader operations. Effective mitigation requires disrupting the entire relay chain rather than addressing isolated compromises.
