Arkanix Stealer, a newly discovered malware operating under a Malware-as-a-Service model, targets a wide range of user data including cryptocurrencies, gaming, and online banking information. The stealer, available in both Python and C++ versions, offers configurable features and employs various techniques to evade detection. It can extract data from multiple browsers, VPNs, and gaming platforms, as well as capture screenshots and RDP connection details. The malware authors promoted their product through a Discord server and implemented a referral program to attract customers. The campaign appears to have been short-lived, with infrastructure taken down around December 2025.
An investigation using Silent Push's Traffic Origin and residential proxy data revealed a suspicious Chinese VPN provider. The analysis focused on IP address 205.198.91.155, which showed unusual traffic from Russia, China, Myanmar, Iran, and Venezuela. This IP was linked to the domain lvcha.in, hosting a Chinese-language VPN. Further investigation uncovered nearly 50 related domains promoting the same VPN, suggesting attempts to bypass country-level firewalls. The VPN's infrastructure was found to use residential proxies and had connections to various high-risk countries. This case study demonstrates the importance of verifying physical and technical behaviors of connections to protect against fraud and state-sponsored actors using stolen identities and spoofed locations.
The Chinese APT group Silver Fox has launched an SEO poisoning campaign targeting Chinese-speaking users, impersonating Microsoft Teams. The campaign uses a modified ValleyRAT loader with Cyrillic elements to mislead attribution. Silver Fox aims to conduct espionage and financial fraud, posing a significant threat due to its dual mission. The attack chain involves a fake Teams website, malicious ZIP files, and binary data retrieval from XML and JSON files. The malware exploits rundll32.exe for binary proxy execution and establishes C2 communication. Attribution to Silver Fox is based on overlapping infrastructure and links to previous campaigns. Organizations with global operations, especially in China, are advised to implement robust security measures and logging capabilities to defend against this evolving threat.
The Silent Lynx APT group has been conducting espionage campaigns targeting diplomatic entities and critical infrastructure in Central Asia, Russia, and China. Two major campaigns were identified: one focused on Russia-Azerbaijan relations and another on China-Central Asia relations. The group used various malware tools including PowerShell scripts, .NET implants, and C++ reverse shells. They leveraged spear-phishing emails with malicious attachments and GitHub-hosted payloads. Key targets included government think-tanks, diplomats, and entities in mining, transport and communication industries. The campaigns coincided with important summits and meetings between the targeted countries. Attribution was based on similarities in tactics, tools, and victimology to previous Silent Lynx operations.
CVE-2025-12357 is a medium-severity vulnerability in the ISO 15118-2 protocol used by electric vehicle (EV) chargers. It involves manipulation of the Signal Level Attenuation Characterization (SLAC) protocol via spoofed measurements, enabling a man-in-the-middle (MitM) attack between an EV and its charger. The attack can be conducted wirelessly within close proximity through electromagnetic induction, without requiring authentication or user interaction. This vulnerability impacts confidentiality, integrity, and availability of the charging communication, potentially allowing attackers to intercept or alter charging commands and data. No known exploits are currently in the wild, and no patches have been published yet. Organizations deploying ISO 15118-2 compliant EV chargers should prioritize mitigation to prevent unauthorized access and data manipulation. Countries with significant EV adoption and infrastructure, such as the United States, Germany, China, Japan, and others, are at higher risk. The vulnerability’s CVSS score is 6.3, reflecting medium severity due to its remote attack vector but limited scope and impact. Defenders should implement network segmentation, monitor for anomalous SLAC traffic, and apply vendor updates once available.
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 TAOTH campaign leveraged an abandoned Sogou Zhuyin IME update server and spear-phishing operations to deliver multiple malware families, primarily targeting users across Eastern Asia. Attackers employed sophisticated infection chains, such as hijacked software updates and fake cloud storage or login pages, to distribute malware and collect sensitive information. The campaign focused on high-value targets, including dissidents, journalists, researchers, and technology/business leaders in China, Taiwan, Hong Kong, Japan, South Korea, and overseas Taiwanese communities. Infrastructure and tool analysis link TAOTH to previously documented threat activity, showing shared C&C infrastructure, malware variants, and tactics indicative of a single, persistent attacker group with a focus on reconnaissance, espionage, and email abuse.
Operation DRAGONCLONE is an advanced cyber espionage campaign active since March 2025 targeting China Mobile Tietong and potentially European telecom organizations connected to Chinese infrastructure. It employs sophisticated malware loaders such as VELETRIX and the VShell adversary simulation tool, delivered via malicious ZIP files exploiting DLL sideloading and anti-analysis techniques like IPFuscation. The campaign is linked to China-nexus threat groups UNC5174 (Uteus) and Earth Lamia and uses tools including SuperShell, Cobalt Strike, and Asset Lighthouse System. Its objectives include credential theft, network reconnaissance, and callback execution. Germany, France, and the UK are identified as higher-risk countries due to their telecom sectors and economic ties to China. The threat is assessed as high severity given its advanced evasion techniques and espionage intent.
Chaos RAT is an open-source remote administration tool written in Golang that has evolved since 2022 to support both Linux and Windows platforms. A critical vulnerability identified as CVE-2024-30850 exists in its web control panel, allowing remote code execution on the server. Although currently limited in usage, Chaos RAT's low detection profile enables threat actors to perform espionage, data exfiltration, and maintain persistent access. The malware employs multiple techniques including privilege escalation, persistence, and command and control communications. Organizations should prioritize patching the vulnerable control panel, restrict access to administrative interfaces, and monitor for indicators of compromise. The threat is assessed as high severity due to its potential impact and ease of exploitation without user interaction. Patch status is not confirmed; no official fix or patch links are provided. The affected platforms include Linux and Windows systems. No specific countries are identified as targeted, but those with significant Linux and Windows server use and strategic geopolitical interests may be at higher risk.
An issue in Beijing Digital China Yunke Information Technology Co.Ltd v.7.2.6.120 allows a remote attacker to execute arbitrary code via the code/function/dpi/web_auth/customizable.php file
