status: experimental
description: This rule identifies Windows file creation events associated with a suspected Axios NPM supply-chain compromise, focusing on specific executables and script payloads created in user temp and ProgramData. Attackers use these artifacts to deliver and execute malicious post-install behavior via Windows scripting and command utilities. The detection relies on file event telemetry that records the creating image path (node.exe or powershell.exe) and the target filenames/paths created under C:\ProgramData and C:\Users\...\AppData\Local\Temp.

What it detects

This rule identifies Windows file creation events associated with a suspected Axios NPM supply-chain compromise, focusing on specific executables and script payloads created in user temp and ProgramData. Attackers use these artifacts to deliver and execute malicious post-install behavior via Windows scripting and command utilities. The detection relies on file event telemetry that records the creating image path (node.exe or powershell.exe) and the target filenames/paths created under C:\ProgramData and C:\Users\...\AppData\Local\Temp.
