The prolific China-connected country-condition actor acknowledged as APT41 has been linked to two beforehand undocumented strains of Android spyware named WyrmSpy and DragonEgg.
“Recognized for its exploitation of web-struggling with purposes and infiltration of classic endpoint gadgets, an set up danger actor like APT 41 which includes cell in its arsenal of malware displays how mobile endpoints are higher-price targets with coveted company and personal knowledge,” Lookout claimed in a report shared with The Hacker Information.
APT41, also tracked under the names Axiom, Blackfly, Brass Typhoon (formerly Barium), Bronze Atlas, HOODOO, Wicked Panda, and Winnti, is known to be operational due to the fact at least 2007, concentrating on a wide vary of industries to conduct mental house theft.

The latest attacks mounted by the adversarial collective have leveraged an open-supply pink teaming software regarded as Google Command and Command (GC2) as element of attacks aimed at media and work platforms in Taiwan and Italy.
The first intrusion vector for the cellular surveillanceware marketing campaign is not recognized, though it is suspected to have concerned the use of social engineering. Lookout mentioned it very first detected WyrmSpy as early as 2017 and DragonEgg at the start of 2021, with new samples of the latter noticed as recently as April 2023.
WyrmSpy primarily masquerades as a default procedure app applied for exhibiting notifications to the user. Later variants, however, have packaged the malware into applications impersonating as adult movie written content, Baidu Waimai, and Adobe Flash. On the other hand, DragonEgg has been distributed in the kind of third-party Android keyboards and messaging apps like Telegram.
There is no evidence that these rogue applications have been distributed as a result of the Google Perform Keep.
WyrmSpy and DragonEgg’s connections to APT41 come 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”) formerly recognized as linked with the group’s infrastructure.
Once set up, both strains of malware request intrusive permissions and occur equipped with complex details selection and exfiltration abilities, harvesting users’ images, locations, SMS messages and audio recordings.
The malware has also been noticed relying on modules that are downloaded from a now-offline C2 server right after the set up of the app to facilitate the facts selection, though at the same time steering clear of detection.
WyrmSpy, for its aspect, is able of disabling Security-Enhanced Linux (SELinux), a security attribute in Android, and making use of rooting equipment such as KingRoot11 to receive elevated privileges on the compromised handsets. A notable function of DragonEgg is that it establishes make contact with with the C2 server to fetch an not known tertiary module that poses as a forensics program.

“The discovery of WyrmSpy and DragonEgg is a reminder of the escalating menace posed by highly developed Android malware,” Kristina Balaam, a senior risk researcher at Lookout, mentioned. “These spy ware offers are extremely refined and can be applied to accumulate a huge assortment of details from infected products.”
The results occur as Mandiant disclosed the evolving methods adopted by Chinese espionage crews to fly less than the radar, like weaponizing networking units and virtualization computer software, employing botnets to obfuscate visitors amongst C2 infrastructure and sufferer environments, and tunneling destructive website traffic inside of victim networks as a result of compromised units.
“Use of botnets, proxying traffic in a compromised network, and focusing on edge equipment are not new methods, nor are they one of a kind to Chinese cyber espionage actors,” the Google-owned risk intelligence firm claimed. “Even so, all through the last decade, we have tracked Chinese cyber espionage actors’ use of these and other techniques as element of a broader evolution towards additional purposeful, stealthy, and productive operations.”
