Defending Against the Rising Threat: Chinese and N. Korean Hackers Target Global Infrastructure

Suspected State-Sponsored Threat Actors Target Government and Critical Infrastructure Sectors

In recent years, threat actors believed to have connections to China and North Korea have been actively involved in launching ransomware and data encryption attacks against government and critical infrastructure sectors worldwide. The attacks have occurred between 2021 and 2023, causing significant disruptions and compromising sensitive information.

ChamelGang and Chinese/North Korean Actors

Two distinct clusters of malicious activities have been identified in these attacks. The first cluster is associated with a group known as ChamelGang, also sometimes referred to as CamoFei. This group has been responsible for a series of targeted ransomware attacks, inflicting damage on government entities and critical infrastructure.

The second cluster overlaps with previous cyber operations conducted by state-sponsored actors from China and North Korea. These threat actors have a history of engaging in offensive cyber activities aimed at compromising networks and exploiting vulnerabilities for strategic purposes.

Global Impact and Security Concerns

The targeted nature of these attacks on government and critical infrastructure sectors has raised significant security concerns globally. The ability of threat actors to disrupt essential services and compromise sensitive data poses a severe threat to national security and public safety.

Furthermore, the suspected ties to state-sponsored entities indicate a coordinated effort to undermine the cybersecurity defenses of nations worldwide. The sophisticated tactics and techniques employed by these threat actors highlight the need for enhanced cybersecurity measures and greater cooperation among international allies to combat such threats effectively.

Recommendations for Mitigating Cyber Threats

In light of these developments, organizations in government and critical infrastructure sectors are urged to implement robust cybersecurity measures to mitigate the risk of ransomware and data encryption attacks. Some key recommendations for enhancing cybersecurity posture include:

Regular Security Assessments

Conducting regular security assessments to identify vulnerabilities and weaknesses in the network infrastructure.

Endpoint Security Solutions

Deploying endpoint security solutions to detect and prevent malware attacks targeting endpoints and devices.

Employee Training

Providing comprehensive cybersecurity training to employees to raise awareness about phishing scams and social engineering tactics used by threat actors.

Incident Response Planning

Developing an incident response plan to effectively respond to and recover from cyberattacks, including ransomware incidents.

Collaboration and Information Sharing

Collaboration and information sharing among government agencies, cybersecurity firms, and international partners are crucial in addressing the evolving threat landscape posed by state-sponsored cyber actors. By sharing threat intelligence and coordinating response efforts, organizations can enhance their collective resilience against cyber threats.


The increasing prevalence of ransomware and data encryption attacks targeting government and critical infrastructure sectors underscores the need for proactive cybersecurity measures and close collaboration among stakeholders. By staying vigilant and adopting a comprehensive cybersecurity strategy, organizations can better protect themselves against sophisticated cyber threats orchestrated by state-sponsored actors.
