About this tag
The PassiveNeuron tag covers a server-focused cyberespionage campaign targeting Windows Server hosts, as documented by Kaspersky's GReAT team. The campaign uses bespoke implants like Neursite and NeuralExecutor alongside commodity tools such as Cobalt Strike to establish stealthy, persistent footholds in government, financial, and industrial networks across Asia, Africa, and Latin America. Activity was observed from December 2024 through at least August 2025, with a multi-stage DLL loader chain enabling low-noise access. This tag is relevant for IT security professionals and Windows Server administrators monitoring advanced persistent threats and server-side malware.
