# MAL-2026-3748: Malicious code in @pelmnaads/naads-common-logger (npm)


- **Type:** Malicious package
- **Package:** `@pelmnaads/naads-common-logger` (npm)
- **Published:** 14 May 2026

## What is MAL-2026-3748?

MAL-2026-3748 is a malicious package in @pelmnaads/naads-common-logger, published on 14 May 2026. 

### Official description

The package is published to the public npm registry under `@pelmnaads/naads-common-logger` with version `19999.0.1` — the canonical dependency-confusion pattern, where an abnormally high version is used to make npm's resolver prefer this public package over a private internal package of the same name. On `npm install`, a `preinstall` lifecycle script (preinstall.js:5-9) makes an HTTPS GET to `h5nvwrz2815ubw84cpkwhezm5db9z1nq.b.mburpcollab.com` with query parameters `package=<npm_package_name>&hostname=<os.hostname()>`, transmitting the installer's hostname off-host to a Burp Collaborator out-of-band interaction endpoint. The README states this is an authorized security test, but the code path and effect on an unsuspecting installer are identical to a hostile dependency-confusion attack: build hosts silently disclose their identity to a third-party domain during `npm install`, with no opt-in. Any build system that resolves this package (e.g., an internal Pelmorex pipeline expecting the private `@pelmnaads/naads-common-logger`) would leak hostname data.

## What should I do about MAL-2026-3748?

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