Potential Ransomware Behavior - Note Files by System

This rule identifies the creation of multiple files with same name and over SMB by the same user. This behavior may indicate the successful remote execution of a ransomware dropping file notes to different folders.

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.

The rule states no platform. This is derived from the 4 ATT&CK techniques it maps to.

Detections can measure how the public catalogue is used — which detections people look for, and which pages bring them here. It sets a cookie that recognises this browser for 180 days. It is never linked to an account and never follows you to other sites. Privacy notice
