The prolific China-linked country-state actor recognised as APT41 has been linked to two previously undocumented strains of Android spy ware named WyrmSpy and DragonEgg.
“Recognized for its exploitation of web-going through programs and infiltration of common endpoint products, an established danger actor like APT 41 which includes cellular in its arsenal of malware shows how cellular endpoints are substantial-benefit targets with coveted company and particular knowledge,” Lookout said in a report shared with The Hacker News.
APT41, also tracked under the names Axiom, Blackfly, Brass Storm (previously Barium), Bronze Atlas, HOODOO, Wicked Panda, and Winnti, is regarded to be operational given that at minimum 2007, targeting a large variety of industries to perform mental home theft.
The latest attacks mounted by the adversarial collective have leveraged an open-resource red teaming resource recognized as Google Command and Manage (GC2) as portion of assaults aimed at media and career platforms in Taiwan and Italy.
The preliminary intrusion vector for the cell surveillanceware marketing campaign is not known, although it is really suspected to have concerned the use of social engineering. Lookout stated it 1st detected WyrmSpy as early as 2017 and DragonEgg at the begin of 2021, with new samples of the latter noticed as lately as April 2023.
WyrmSpy principally masquerades as a default process application employed for displaying notifications to the person. Afterwards variants, even so, have packaged the malware into apps impersonating as grownup online video content, Baidu Waimai, and Adobe Flash. On the other hand, DragonEgg has been distributed in the variety of 3rd-celebration Android keyboards and messaging applications like Telegram.
There is no evidence that these rogue applications have been dispersed by the Google Engage in Shop.
WyrmSpy and DragonEgg’s connections to APT41 crop up from the use of a command-and-server (C2) with the IP deal with 121.42.149[.]52, which resolves to a domain (“vpn2.umisen[.]com”) beforehand identified as related with the group’s infrastructure.
Once set up, both strains of malware ask for intrusive permissions and arrive fitted with refined details assortment and exfiltration abilities, harvesting users’ images, places, SMS messages and audio recordings.
The malware has also been noticed relying on modules that are downloaded from a now-offline C2 server just after the installation of the application to facilitate the knowledge selection, although at the same time keeping away from detection.
WyrmSpy, for its element, is able of disabling Security-Improved Linux (SELinux), a security attribute in Android, and generating use of rooting resources such as KingRoot11 to get elevated privileges on the compromised handsets. A notable attribute of DragonEgg is that it establishes get in touch with with the C2 server to fetch an unknown tertiary module that poses as a forensics system.

“The discovery of WyrmSpy and DragonEgg is a reminder of the growing risk posed by advanced Android malware,” Kristina Balaam, a senior menace researcher at Lookout, said. “These spyware packages are very complex and can be applied to obtain a large variety of data from infected gadgets.”
The conclusions arrive as Mandiant disclosed the evolving tactics adopted by Chinese espionage crews to fly less than the radar, like weaponizing networking devices and virtualization program, utilizing botnets to obfuscate website traffic between C2 infrastructure and victim environments, and tunneling destructive website traffic within of victim networks through compromised systems.
“Use of botnets, proxying visitors in a compromised network, and concentrating on edge gadgets are not new strategies, nor are they one of a kind to Chinese cyber espionage actors,” the Google-owned risk intelligence firm reported. “Having said that, for the duration of the final ten years, we have tracked Chinese cyber espionage actors’ use of these and other ways as section of a broader evolution toward additional purposeful, stealthy, and successful functions.”
