RMM Software Installation from a Commonly Abused Web Service

Description

Identifies Windows Installer (MSI) packages that originate from commonly abused web services and install a recognized remote monitoring and management (RMM) product. Adversaries may abuse legitimate RMM software in social engineering campaigns to gain remote access and control over victim systems. This rule does not establish that the origin, installer, or RMM product is inherently malicious. Origins outside this set are covered by the companion rule "RMM Software Installation from an Internet-Originated MSI".

Detection logic

Its licence does not clear it for publishing here

Sunturai publishes a detection's own text where the licence it arrived under has been reviewed and permits it, and Elastic License 2.0 has not. The query as its source wrote it, its canonical form and the hash that pins this revision are in the workspace record.

Detection requirements

Platform: ESXi Linux macOS Network Devices Windows
The rule states no platform. This is derived from the 3 ATT&CK techniques it maps to.

Known benign triggers

Authorized IT or managed service provider deployment of remote monitoring and management software through public, vendor, or software distribution infrastructure can produce this behavior.
