# MAL-2026-12329: Malicious code in @shiftmarkets/shift-sdk-v4 (npm)


- **Type:** Malicious package
- **Package:** `@shiftmarkets/shift-sdk-v4` (npm)
- **Published:** 5 Aug 2026

## What is MAL-2026-12329?

MAL-2026-12329 is a malicious package in @shiftmarkets/shift-sdk-v4, published on 5 Aug 2026. 

### Official description

The package declares a postinstall script `node dist/recon.js` that runs automatically on `npm install`. The script collects installer-side reconnaissance data — hostname, username, SUDO_USER, home directory, current working directory, all local IPv4 addresses (including internal interfaces), DNS domain (via `dnsdomainname`), CI-provider flags, the full sorted list of `process.env` variable names, and a filtered subset of environment variable names matching secret/credential regex patterns — and POSTs the JSON payload over plain HTTP to the hardcoded bare IPv4 endpoint `http://138.68.108.20:80/cb`. An in-file comment frames the beacon as 'NON-SENSITIVE telemetry', but the destination is a bare IP with no publisher affiliation and the payload includes internal network topology and credential-shaped env variable names. The package presents itself as a scoped Shift Forex build compatible with the public `shift-sdk-v4` package and ships a minimal API-compatible stub in `dist/index.js`, consistent with a dependency-confusion lure against consumers who reference `shift-sdk-v4` from an internal registry.

## What should I do about MAL-2026-12329?

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