Beginning in August 2025, a sophisticated intrusion was discovered where attackers used log poisoning techniques to deploy a web shell on vulnerable phpMyAdmin panels. The threat actors exploited misconfigured web applications to plant China Chopper web shells, controlled via AntSword, before deploying Nezha, an open-source monitoring tool, to facilitate remote command execution. This led to the deployment of Ghost RAT on compromised systems. Analysis revealed over 100 compromised machines, predominantly located in Taiwan, Japan, South Korea, and Hong Kong. The attackers demonstrated technical proficiency through multi-stage operations, utilizing AWS and VPS infrastructure, with indicators pointing to China-nexus threat actors. The campaign highlights increasing abuse of legitimate publicly available tools to achieve malicious objectives while maintaining plausible deniability.

A sophisticated cyber intrusion campaign utilizing log poisoning and a new tool called Nezha has been uncovered. The attackers exploited a vulnerable phpMyAdmin interface to deploy a web shell, followed by the installation of Nezha, an open-source server monitoring tool repurposed for malicious activities. The campaign targeted over 100 victims, primarily in Taiwan, Japan, South Korea, and Hong Kong. The threat actors also deployed Ghost RAT, a remote access trojan, for further system compromise. The attack methodology and victimology suggest a China-nexus threat actor, highlighting the need for improved security measures and vigilance against emerging threats.

Phantom Taurus, a newly identified Chinese state-sponsored threat actor, has been conducting espionage operations targeting government and telecommunications organizations across Africa, the Middle East, and Asia. The group's primary focus includes ministries of foreign affairs, embassies, and military operations, with the objective of gathering sensitive information. Phantom Taurus employs distinctive tactics, techniques, and procedures, including a new malware suite called NET-STAR. This suite consists of three web-based backdoors designed to target Internet Information Services (IIS) web servers. The group has recently shifted from targeting emails to directly accessing databases, demonstrating their ability to adapt and evolve their methods. Phantom Taurus' activities align with Chinese strategic interests, and their infrastructure overlaps with other known Chinese APT groups.

Chinese-speaking threat actors, dubbed UAT-6382, have been exploiting a remote-code-execution vulnerability (CVE-2025-0994) in Cityworks, a popular asset management system. The attacks, which began in January 2025, target local governing bodies in the United States, focusing on utilities management systems. The threat actors deploy various web shells, including AntSword and Chopper, and use custom Rust-based loaders called TetraLoader to deliver Cobalt Strike beacons and VSHell malware. The attackers conduct reconnaissance, enumerate directories, and stage files for exfiltration. Their tooling and tactics indicate a high level of proficiency in the Chinese language, suggesting a Chinese origin for the threat group.
