A Deep Dive into Water Gamayun’s Arsenal and Infrastructure

Trend Research discusses the delivery methods, custom payloads, and techniques used by Water Gamayun, the suspected Russian threat actor abusing a zero-day vulnerability in the Microsoft Management Console framework (CVE-2025-26633) to execute malicious code on infected machines.

This blog entry delves into MxDR's unraveling of the AsyncRAT infection chain across multiple cases, shedding light on the misuse of aspnet_compiler.exe, a legitimate Microsoft process originally designed for precompiling ASP.NET web applications.
