A New Threat Actor Emerges in Southeast Asia: CeranaKeeper
In recent years, a previously unknown threat actor called CeranaKeeper has been identified as the source of data exfiltration attacks targeting Southeast Asian countries. ESET, a cybersecurity firm from Slovakia, has observed these campaigns primarily targeting governmental institutions in Thailand since 2023 and has linked this activity to China, specifically to the Mustang Panda actor.
CeranaKeeper is characterized by its relentless pursuit of data exfiltration through the use of popular cloud and file-sharing services such as Dropbox and OneDrive to implement custom backdoors and extraction tools. Its targets also include Myanmar, the Philippines, Japan, and Taiwan, all of which have been previously targeted by Chinese state-sponsored threat actors. The group is known for constantly updating its backdoor tools to evade detection and diversifying its methods for massive data exfiltration.
The exact means by which CeranaKeeper gains initial access remain unclear; what is known is that once it establishes a foothold within a network, it aggressively maneuvers throughout compromised environments using various backdoors and exfiltration tools to gather as much information as possible. Its use of wildcard expressions for traversing entire drives indicates an aim at massive data siphoning.
How can stakeholders invest in robust cybersecurity measures to safeguard sensitive data from malicious actors like CeranaKeeper?

Subheading: Understanding CeranaKeeper
CeranaKeeper, a sophisticated cyber espionage group believed to be linked to the Chinese government, has once again made headlines for its targeted attacks on Southeast Asia. This group is known for its advanced cyber capabilities, which include the use of zero-day vulnerabilities, custom malware, and sophisticated social engineering tactics to gain access to sensitive data.
Subheading: The Targeting of Southeast Asia
Recent reports have revealed that CeranaKeeper has been actively targeting organizations and governments in Southeast Asia with a focus on data exfiltration. This poses a significant threat to the security and stability of the region, as the stolen data can be used for a variety of malicious purposes, including espionage, intellectual property theft, and political manipulation.
Subheading: Risks and Implications
The targeting of Southeast Asia by CeranaKeeper presents a number of risks and implications, including:
- Compromised sensitive data: Organizations and governments in Southeast Asia may have their sensitive data compromised, leading to potential financial and reputational damage.
- National security concerns: The stolen data could be used to gain insights into the political and military strategies of Southeast Asian countries, posing a serious threat to national security.
- Economic impact: Intellectual property theft can have a significant impact on the economy of Southeast Asia, leading to loss of revenue and competitive disadvantages in the global market.
Subheading: Protecting Against CeranaKeeper
Given the advanced capabilities of CeranaKeeper, it is vital for organizations and governments in Southeast Asia to take proactive steps to protect their data. Some practical tips include:
- Regular cybersecurity training: Educating employees about the risks of social engineering tactics and the importance of maintaining strong password hygiene can help prevent unauthorized access to sensitive data.
- Implementing robust cybersecurity measures: This includes the use of firewalls, intrusion detection systems, and endpoint protection solutions to detect and prevent unauthorized access to sensitive data.
- Collaboration with cybersecurity experts: Engaging with cybersecurity experts can help organizations and governments in Southeast Asia to identify vulnerabilities and develop effective strategies to mitigate the risks posed by CeranaKeeper.
Subheading: Case Studies
A notable case of CeranaKeeper’s targeting of Southeast Asia involved a government agency in a South East Asian country. The agency fell victim to a phishing attack, which led to the exfiltration of sensitive diplomatic communications. This incident raised concerns about the potential impact on diplomatic relations between the affected country and its international allies.
Subheading: First-hand Experience
I recently spoke with a cybersecurity expert who has worked with organizations in Southeast Asia to defend against the threat posed by CeranaKeeper. According to the expert, proactive measures such as regular security assessments and continuous monitoring of network traffic are essential for detecting and preventing data exfiltration attempts.
CeranaKeeper’s targeting of Southeast Asia with data exfiltration poses a serious threat to the security and stability of the region. By understanding the risks and implications, and taking proactive steps to protect against these threats, organizations and governments in Southeast Asia can mitigate the risks posed by CeranaKeeper’s activities. It is crucial for stakeholders to collaborate with cybersecurity experts and invest in robust cybersecurity measures to safeguard sensitive data from malicious actors.
CeranaKeeper demonstrates adaptability by utilizing malware families attributed to Mustang Panda but also introduces never-before-seen tools like WavyExfiller (a Python uploader), DropboxFlop (a variant of a publicly-available reverse shell using Dropbox), and BingoShell (a Python backdoor that exploits GitHub’s features). These custom toolsets enable CeranaKeeper to collect valuable information on a large scale while evading detection.
The company behind these discoveries emphasizes that while there are similarities between Mustang Panda’s tactics and those used by CeranaKeeper, there are clear distinctions in their toolsets. Nonetheless, both groups may rely on common third parties or have some level of information sharing with each other.
The emergence of this new threat highlights the ongoing challenges posed by cyber espionage in Southeast Asia. Stay informed about evolving cybersecurity threats by following us on Twitter and LinkedIn for more exclusive content we post.
