Daggerfly Enhances Malware Toolkit to Target All Major Operating Systems
Introduction
The Chinese espionage group Daggerfly, also known as Evasive Panda or Bronze Highland, has significantly upgraded its malware arsenal, allowing it to target a wide range of operating systems including Windows, Linux, macOS, and Android. This development marks a notable escalation in the group's cyber capabilities, as detailed in a recent analysis by Symantec. The updated toolkit underscores the group's sophisticated approach to espionage and highlights the increasing threat posed by advanced persistent threat (APT) groups.
Daggerfly's Evolution and Recent Activities
Daggerfly has been active for over a decade, focusing on both international and domestic espionage. Known for its MgBot malware framework, the group has a history of leveraging advanced malware for information gathering.
- Past Operations: In April 2023, Symantec reported on Daggerfly’s campaign targeting a telecommunications organization in Africa, where the group utilized new plugins developed with the MgBot framework. Additionally, ESET documented Daggerfly's ongoing campaigns targeting Tibetan individuals globally in March 2024, using a previously undocumented backdoor named Nightdoor.
- Recent Updates: According to Symantec’s latest analysis, Daggerfly has recently expanded its malware toolkit to include updated versions of its existing tools and new malware. The group has been observed deploying these updated tools in attacks against organizations in Taiwan and a U.S. NGO operating in China.
Latest Malware Developments
- acma Backdoor: One of the notable updates is the macOS backdoor Macma, which Symantec links to Daggerfly. Originally discovered by Google in 2021, Macma has been operational since at least 2019. It features functionalities for data exfiltration such as device fingerprinting, screen capture, keylogging, and audio recording. The updated version of Macma includes enhanced debugging and new features, demonstrating Daggerfly’s ability to rapidly adapt its toolset.
- Shared Framework: A key feature of Daggerfly's malware is the use of a shared framework or library that facilitates the development of malware across different operating systems. This framework has been used to create threats for Windows, macOS, Linux, and Android platforms. The shared codebase includes the Suzafk backdoor, also known as Nightdoor, which was first documented by ESET in March 2024. Suzafk is a multi-staged backdoor that uses TCP or OneDrive for command and control (C&C) and reflects the group’s continued evolution in malware development.
- Android and Solaris Targets: Symantec’s analysis also uncovered Daggerfly’s capability to Trojanize Android APKs and intercept SMS and DNS requests. Additionally, there is evidence suggesting the group is developing malware targeting Solaris OS, further illustrating its broad targeting capabilities.
Conclusion
Daggerfly’s latest malware updates highlight the group's ongoing commitment to refining its espionage toolkit and expanding its reach across various operating systems. As cyber threats continue to evolve, it is crucial for organizations to stay vigilant and implement robust security measures. This includes using advanced threat detection solutions and regularly updating security protocols to defend against sophisticated malware and cyber-attacks.
