Silver Fox, a threat actor, is exploiting Japan's tax filing and organizational change season with a targeted spearphishing campaign against Japanese businesses. The group sends convincing phishing emails related to tax compliance, salary adjustments, and HR matters, tricking recipients into opening malicious links or attachments. The campaign capitalizes on the high volume of legitimate financial and HR communications during this period, increasing the risk of compromise. Silver Fox has expanded its targets from Chinese-speaking entities to Southeast Asia, Japan, and potentially North America. The group uses ValleyRAT, a remote access trojan, to gain control of compromised machines and steal sensitive information. To protect against this threat, organizations should increase vigilance, reinforce awareness about phishing attempts, and verify the authenticity of tax- and HR-themed requests.

Check Point Research has identified a Chinese-nexus advanced persistent threat group named Silver Dragon, targeting organizations in Southeast Asia and Europe since mid-2024. The group, likely operating under APT41, exploits public-facing servers and uses phishing emails for initial access. They deploy custom tools including GearDoor, a backdoor using Google Drive for command and control, SSHcmd for remote access, and SilverScreen for covert screen monitoring. Silver Dragon primarily focuses on government entities, utilizing Cobalt Strike beacons and DNS tunneling for communication. The group's sophisticated tactics and evolving toolkit demonstrate a well-resourced and adaptable threat actor.
Key Findings Introduction In recent months, Check Point Research (CPR) has been tracking a sophisticated, Chinese-aligned threat group whose activity demonstrates operational correlation with campaigns previously associated with APT41. We have designated this activity cluster as Silver Dragon. This group actively targets organizations in Southeast Asia and Europe, with a particular focus on government entities.

In January 2026, a new variant of the PlugX malware was observed being used in targeted attacks. Analysis suggests involvement of the UNC6384 APT group, linked to Mustang Panda, targeting government agencies in Southeast Asia. The malware uses a browser updater disguise to download and execute a malicious MSI file, leading to PlugX infection. The STATICPLUGIN downloader uses a revoked code-signing certificate from a Chinese company. The PlugX variant employs DLL sideloading and shellcode execution techniques. Its configuration is encrypted using RC4 and custom encoding. C2 servers were identified as fruitbrat[.]com and 108.165.255[.]97:443. The ongoing improvements to PlugX indicate its continued use in targeted attacks by APT groups.

This intelligence report details a hybrid cryptocurrency investment scam campaign targeting users in Asia, particularly Japan. The scam combines malvertising techniques to attract victims with pig butchering tactics using AI-powered chatbots for sustained engagement. Victims are lured through social media ads impersonating financial experts, directed to lure websites, and then to messaging apps where automated bots manipulate them into making increasingly large investments. The campaign uses over 23,000 domains, many generated algorithmically, and shows signs of expanding globally. This approach represents a scalable, automated evolution of traditional investment fraud methods, potentially transforming labor-intensive scams into more efficient operations.
A Chinese-speaking threat actor group, tracked as CL-UNK-1037, has been conducting a large-scale SEO poisoning campaign called Operation Rewrite. The attackers use a malicious IIS module named BadIIS to intercept and alter web traffic on compromised servers, manipulating search engine results to redirect users to malicious sites. The campaign primarily targets East and Southeast Asia, with a focus on Vietnam. The attackers employ various tools including native IIS modules, ASP.NET handlers, and PHP scripts. The operation shows links to previously known threat groups like Group 9 and possibly DragonRank. The campaign demonstrates sophisticated techniques for search result manipulation and traffic redirection, posing significant risks to unsuspecting internet users.
The 'Game of Emperor' report details a persistent cyber intrusion campaign by the threat actor 'Earth Estries' targeting sectors such as consulting, managed service providers, NGOs, and telecoms. The campaign affects multiple countries primarily outside Europe, including Afghanistan, Brazil, India, Indonesia, Malaysia, Pakistan, Philippines, South Africa, Taiwan, Thailand, USA, and Vietnam. There are no known exploits or patches associated with this threat. The campaign is ongoing but assessed as medium severity due to its persistence and potential indirect risks to European organizations through global supply chains.
