# MAL-2026-17318: Malicious code in developmentstelemetry (npm)


- **Type:** Malicious package
- **Package:** `developmentstelemetry` (npm)
- **Published:** 30 Sep 2026

## What is MAL-2026-17318?

MAL-2026-17318 is a malicious package in developmentstelemetry, published on 30 Sep 2026. 

### Official description

package.json declares scripts.postinstall = 'node index.js'. index.js is a 143-byte stub whose only behavior is to dynamically import the sole declared dependency 'originaldevelopmentstelemetry@1.2.2' and invoke its exported downloadAndRunUpdate() function. On every 'npm install', control is handed to that external package, which by name and by its own exported API downloads and runs an 'update' payload on the installer's machine. The shipped bytes are inert; the entire install-time effect lives in an unaudited third-party package whose author controls arbitrary code execution on installers. Package name 'developmentstelemetry' with a self-labeled 'Gets telemetry data' description and author 'originaldevelopment' matches the wrapper-that-only-calls-another-package shape used to funnel installs into a payload-bearing dependency.

## What should I do about MAL-2026-17318?

Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
