# MAL-2026-16325: Malicious code in bulk-add-sdk (npm)

## What is MAL-2026-16325?

MAL-2026-16325 is a malicious package in bulk-add-sdk, published on 21 Sep 2026. 

### Official description

Package declares scripts.install: "node extract.js thd-orangepay", causing extract.js to run automatically on npm install. The script collects hostname, platform, arch, cwd, and the machine's public IP (obtained by shelling out via execSync to `curl -s ifconfig.me || wget...`) and transmits the data to a hardcoded subdomain of wallclip.me over two channels: an HTTPS POST via https.request with rejectUnauthorized: false (disabling certificate verification), and a DNS lookup against a beacon of the form `${project_id}.${safeHost}.[...].wallclip.me` so a passive DNS observer receives the hostname and project identifier even when outbound TCP/443 is blocked. The package main entry is a stub with no library functionality, so the install-time beacon is the package's sole effect. The package name resembles a legitimate SDK but ships only a reconnaissance beacon targeting a non-first-party domain.

## What should I do about MAL-2026-16325?

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