The PassiveNeuron campaign is a sophisticated cyberespionage operation targeting Windows Server machines primarily in government, financial, and industrial sectors across Asia, Africa, and Latin America. Attackers gain initial access by exploiting SQL servers and deploy custom implants such as Neursite and NeuralExecutor. These implants employ advanced persistence, evasion, and command execution techniques, using a multi-stage loading process and diverse communication protocols for command and control (C2). Although attribution is uncertain, indicators suggest possible links to Chinese-speaking threat actors. The campaign highlights the critical need for robust server security and continuous monitoring to detect complex multi-stage intrusions. No known exploits are currently in the wild, and the campaign is rated medium severity. The focus on Windows Server environments and SQL exploitation techniques underscores the risk to organizations relying on these technologies.

The analysis team has categorized attacks on MS-SQL and MySQL servers installed on Windows systems during Q2 2025. While the number of targeted systems remains stable, attacks on MS-SQL servers have been decreasing. MySQL servers saw a significant spike in attacks in June 2025. The report provides detailed statistics on attack trends, including graphs illustrating the attack status for both server types. It also includes a list of MD5 hashes, URLs, FQDNs, and IP addresses associated with the malicious activities. The analysis covers various types of malware and tools used in these attacks, ranging from backdoors and miners to ransomware and remote access trojans.
