VERY IMPORTANT

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.
