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.

A sophisticated cyber campaign utilizing the open-source Nezha tool has been discovered targeting vulnerable web applications since August 2025. Attackers gained access through an exposed phpMyAdmin panel, employing creative log poisoning techniques to implant a PHP web shell. The intrusion involved the use of AntSword for server control, followed by the installation of Nezha agent and Ghost RAT malware. This marks the first public report of Nezha being used for web server compromises. The campaign, linked to China-based infrastructure, affected over 100 systems, primarily in Taiwan, Japan, South Korea, and Hong Kong. Attackers used Nezha to disable Windows Defender and deploy Ghost RAT, establishing persistence under the name 'SQLlite'. Recommendations include patching public-facing applications, implementing authentication, and improving detection for post-exploitation activities.

A malware campaign targeting Chinese-speaking users has been identified, delivering three types of malware: ValleyRAT, FatalRAT, and kkRAT. The campaign uses fake installer pages to distribute the malware.kkRAT, a new Remote Access Trojan, shares similarities with Ghost RAT and Big Bad Wolf. It employs advanced evasion techniques, including sandbox detection and anti-analysis methods. The malware uses the BYOVD technique to disable antivirus and EDR systems.kkRAT's features include clipboard manipulation for cryptocurrency address replacement and deployment of remote monitoring tools. The malware's network communication protocol is similar to Ghost RAT's but with added encryption.kkRAT supports multiple plugins and commands for various malicious activities.

Two cyberattack campaigns, Operation GhostChat and Operation PhantomPrayers, targeted the Tibetan community in June 2025, coinciding with the Dalai Lama's 90th birthday. These attacks involved strategic web compromises, DLL sideloading, and multi-stage infection chains to deploy Ghost RAT and PhantomNet backdoors. The attackers used social engineering tactics, impersonating legitimate platforms and leveraging culturally significant events to lure victims. Both campaigns employed sophisticated evasion techniques, including code injection and API hook bypassing. The attacks are attributed to China-nexus APT groups based on victimology, malware used, and employed tactics. The campaigns highlight the ongoing cyber threats faced by the Tibetan community and the evolving tactics of state-sponsored threat actors.
