Loading threat actor…
APT41 is a China-linked threat actor associated with both state-aligned cyberespionage and financially motivated cybercrime. It is widely tracked as Winnti, BARIUM, Wicked Panda, Wicked Spider, Double Dragon, Brass Typhoon, and Blackfly; some reporting distinguishes Grayfly and Blackfly as separate operational elements rather than a single unified cluster. The group has targeted organizations in the gaming and telecommunications sectors and has conducted supply-chain compromise activity. APT41 has used spearphishing attachments for initial access, deployed malware through PowerShell, conducted process discovery, and harvested credentials from browser password stores using BrowserGhost. Its operational toolkit has included Linux kernel-module rootkits such as adore-ng and Suterusu to conceal activity, as well as section-mapping-based process injection. APT41 has also exfiltrated collected data through legitimate cloud-storage services, including OneDrive. The group’s combination of espionage-oriented collection and cybercriminal activity distinguishes it from exclusively state-focused intrusion sets.

Among these vulnerabilities, CVE-2019-19781 was the most exploited flaw in 2020... Citrix Netscaler Application Delivery Control (ADC) is vulnerable to RCE and full system compromise due to poor access controls, thus allowing directory traversal.
APT41 used HTTP to download payloads for CVE-2019-19781 and CVE-2020-10189 exploits.
Attack vectors This campaign uses different means to enter and infect a target system: Injection of an SQL script into the system’s Microsoft SQL Server to upload a malicious file Exploitation of the Microsoft Exchange Server ProxyLogon vulnerability CVE-2021-26855 to upload a malicious web shell Possible distribution through emails containing malicious attachments
A Chinese advanced persistent threat tracked as Deep Panda has been observed exploiting the Log4Shell vulnerability in VMware Horizon servers to deploy a backdoor and a novel rootkit on infected machines with the goal of stealing sensitive data. The latest set of attacks documented by Fortinet shows that the infection procedure involved the exploitation of the Log4j remote code execution flaw (aka Log4Shell) in vulnerable VMware Horizon servers.
This detection identifies instances where Windows Explorer.exe spawns PowerShell or cmd.exe processes, particularly focusing on executions initiated by LNK files. This behavior is associated with the ZDI-CAN-25373 Windows shortcut zero-day vulnerability, where specially crafted LNK files are used to trigger malicious code execution through cmd.exe or powershell.exe. This technique has been actively exploited by multiple APT groups in targeted attacks through both HTTP and SMB delivery methods.
