‘Earth Lusca’ Is Concentrating on Governments Internationally
A new threat group linked to China, dubbed “Earth Lusca” by researchers at cybersecurity firm Trend Micro, just isn’t solely working cyberespionage campaigns in opposition to governments as seen in a number of different state-backed campaigns, however it’s also looking for monetary gain- with profitable assaults in opposition to a number of playing firms in China and numerous different cryptocurrency platforms.

Andy Norton, European cyber threat officer at cybersecurity agency Armis, says though this isn’t typical habits for a nation-state risk actor, the actions and targets of Earth Lusca appear to suit the invoice of a nation-state-driven agenda. “Many countries world wide use cyber as a way for gaining political intelligence, whether or not that’s to grasp and adapt overseas coverage, acquire perception into mental property or monitor the exercise of residents,” he says.
The methodologies outlined within the Pattern Micro report are well-known to the business, Norton says – together with the usage of purple herring payloads, such because the noisy Monero miners which might be usually intentionally put in to deflect consideration from the true nature and function of the assault by extra subtle actors.
The Pattern Micro researchers who started monitoring Earth Lusca’s operations in mid-2021 linked the risk actor to a number of publicly recognized assaults that embody:
- Authorities establishments in Taiwan, Thailand, the Philippines, Vietnam, the United Arab Emirates, Mongolia and Nigeria;
- Educational institutions in Taiwan, Hong Kong, Japan and France;
- Media companies in Taiwan, Hong Kong, Australia, Germany and France;
- Professional-democracy and human rights political organizations and actions in Hong Kong;
- COVID-19 research organizations in the US;
- Telecom firms in Nepal;
- Non secular actions which might be banned in mainland China;
- Numerous cryptocurrency buying and selling platforms.
Gambling and cryptocurrency trading are unlawful in China. The researchers say that what seems to be a state-backed risk actor has additionally focused these platforms with cryptocurrency miners, “with the first cryptocurrency goal being Monero [XMR].”
Hyperlinks to APT41 aka Winnti
The researchers say they noticed an in depth resemblance between this group’s strategies, ways and procedures to these of APT41 – which is often known as Winnti, Depraved Spider, Winnti Umbrella and Barium. In truth, Earth Lusca deploys Winnti malware within the superior levels of its marketing campaign, the researchers say.
Regardless of that similarity, nevertheless, the researchers say they take into account Earth Lusca a separate risk actor. However they add: “We do have proof, nevertheless, that the group is a part of the ‘Winnti cluster,’ which is comprised of various teams with the identical origin nation and share elements of their TTPs.”
Primarily based on their operations and utilization, the researchers have grouped Earth Lusca’s operational infrastructure into two clusters:
- First Cluster: This cluster is constructed utilizing digital personal servers rented from a service supplier known as Vultr. It’s used for finishing up watering gap and spear-phishing operations, along with appearing as a command-and-control server for malwares, the researchers say.
- Second Cluster: Aside from appearing as a C&C server – however for Cobalt Strike Beacon – this cluster “acts as a scanning instrument that searches for vulnerabilities in public-facing servers and builds visitors tunnels inside the goal’s community,” the researchers say. In contrast to VPS used within the first cluster, the second comprises compromised servers working outdated, open-source variations of Oracle GlassFish Server.
Assault Vectors Used
Earth Lusca makes use of three main assault vectors, based on researchers. They are saying two of them – spear-phishing and watering gap assaults – contain social engineering and the third assault vector exploits recognized vulnerabilities in merchandise reminiscent of Microsoft Change Server [ProxyShell] and Oracle’s GlassFish.
After profitable exploitation, Earth Lusca deploys one of many a number of payloads or malwares listed beneath for reconnaissance, persistence and lateral motion, the researchers say:
- Doraemon backdoor;
- FunnySwitch backdoor;
- ShadowPad backdoor;
- Winnti malware;
- AntSword internet shell;
- Behinder internet shell.
The risk actors additionally deployed cryptominers that would mine Monero cryptocurrency, based on the researchers, who add that “the income earned from the mining actions appears low.”
Pascal Geenens, director of risk intelligence at Radware, tells ISMG that Chinese language-linked risk teams don’t typically go after financial good points however says: “As soon as the victims have served their function, the state risk group members are allowed to run their very own financially motivated campaigns in opposition to the victims for private acquire.”
Geenens additionally says, “It’s unlikely that Chinese language authorities teams would get entangled in stealing from firms. Nevertheless, given the ban in opposition to cryptocurrencies and playing in mainland China, along with the push for government-regulated Digital Foreign money Digital Cost, or DCEP, it is price maintaining a tally of the scenario.”
