A sophisticated Chinese threat actor, dubbed CL-UNK-1068, has been waging a years-long campaign to infiltrate critical infrastructure in South, Southeast, and East Asia. This report sheds light on the group's tools, techniques, and tactics, providing valuable insights into their attack vectors and capabilities. Organizations in these regions must take proactive measures to protect themselves against this threat.
The CL-UNK-1068 threat actor has been identified as a sophisticated Chinese threat actor waging a years-long campaign to infiltrate critical infrastructure in South, Southeast, and East Asia. The group uses a multi-faceted tool set, including custom malware, modified open-source utilities, and living-off-the-land binaries (LOTBINs), to target various sectors. The attack vectors include exploiting web servers to deliver web shells and moving laterally to other hosts to steal sensitive data or discover vulnerabilities. The group uses legitimate Python executables to launch DLL side-loading attacks, bypassing traditional security measures and maintaining a low profile. The attackers employ tools like Mimikatz, LsaRecorder, DumpItForLinux, and Volatility Framework to facilitate credential theft. The group has utilized custom .NET tools since 2020 for reconnaissance efforts, including the SuperDump tool. The primary objective of the CL-UNK-1068 campaign is cyber espionage, according to security researcher Tom Fakterman with moderate-to-high confidence. Organizations in Asia must remain vigilant and take proactive measures to protect themselves against this threat due to its sophisticated tools and techniques.
A recent report from Palo Alto Networks Unit 42 has shed light on a sophisticated and stealthy threat actor, dubbed CL-UNK-1068, which has been waging a years-long campaign to infiltrate critical infrastructure in South, Southeast, and East Asia. This Chinese threat actor has been identified as the mastermind behind a complex web of attacks targeting various sectors, including aviation, energy, government, law enforcement, pharmaceutical, technology, and telecommunications.
The CL-UNK-1068 campaign is characterized by its multi-faceted tool set, which includes custom malware, modified open-source utilities, and living-off-the-land binaries (LOLBINs). These tools are designed to target both Windows and Linux environments, allowing the adversary to maintain a persistent presence within targeted environments. The attack vectors employed by CL-UNK-1068 include exploiting web servers to deliver web shells and moving laterally to other hosts, with the ultimate goal of stealing sensitive data or discovering vulnerabilities.
A notable aspect of the CL-UNK-1068 campaign is its use of legitimate Python executables to launch DLL side-loading attacks and stealthily execute malicious DLLs. This technique allows the attackers to bypass traditional security measures and maintain a low profile. Additionally, the group has employed a range of tools to facilitate credential theft, including Mimikatz, LsaRecorder, DumpItForLinux, and Volatility Framework.
One of the most intriguing aspects of the CL-UNK-1068 campaign is its use of batch scripts to collect host information and map the local environment. This technique allows the attackers to gather critical information about the targeted systems without arousing suspicion. Furthermore, the group has utilized a custom .NET tool named SuperDump as far back as 2020, which is used for reconnaissance efforts.
The use of Mimikatz, in particular, stands out as a notable aspect of the CL-UNK-1068 campaign. This tool allows the attackers to dump passwords from memory, providing a significant advantage in terms of credential theft. The group's use of LsaRecorder and DumpItForLinux further solidifies their capabilities in this regard.
The CL-UNK-1068 campaign has been attributed to a previously undocumented threat activity group, dubbed CL, which stands for "cluster" and "UNK," representing unknown motivation. However, security researcher Tom Fakterman has assessed with moderate-to-high confidence that the primary objective of the campaign is cyber espionage.
In light of this report, it is clear that the CL-UNK-1068 threat actor poses a significant threat to critical infrastructure in Asia. The group's sophisticated tools and techniques make it difficult for organizations to detect and respond to these attacks effectively. As such, it is essential for organizations in these regions to remain vigilant and take proactive measures to protect themselves against this threat.
