# MAL-2026-4641: Malicious code in platform-tempo (npm)


- **Type:** Malicious package
- **Package:** `platform-tempo` (npm)
- **Published:** 25 May 2026

## What is MAL-2026-4641?

MAL-2026-4641 is a malicious package in platform-tempo, published on 25 May 2026. 

### Official description

platform-tempo@99.0.1 declares a `preinstall` hook that runs `poc.js` on every `npm install`. The script collects host identity (`os.hostname()`, `whoami /all` / `id`, `ipconfig` / `ip a`), the parent project's `package.json`, git remotes, CI configuration files (`.gitlab-ci.yml`, `.github/workflows/*`, `Jenkinsfile`, `azure-pipelines.yml`), and a curated dump of environment variables matching TOKEN/AWS/AZURE/NPM/GITHUB/GITLAB/CI patterns. The collected data is HTTPS POSTed to a hardcoded interactsh OAST domain (`d8a5d9pon5bugoc35cngp9hcregcqyezu.oast.me`) with the package name as the path, plus a DNS beacon to the same host. The package name `platform-tempo` combined with version `99.0.1` is the canonical dependency-confusion shape — designed to be auto-resolved by an internal package resolver in preference to a private package of the same name. Self-described `bug bounty` framing in the package description does not change the install-time impact on any third party whose resolver picks up this public name: their CI tokens, cloud credentials, and source-tree metadata are shipped to the attacker-controlled OAST endpoint.

## What should I do about MAL-2026-4641?

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