# MAL-2026-6346: Malicious code in triage-bot (npm)


- **Type:** Malicious package
- **Package:** `triage-bot` (npm)
- **Published:** 23 Jun 2026

## What is MAL-2026-6346?

MAL-2026-6346 is a malicious package in triage-bot, published on 23 Jun 2026. 

### Official description

package.json declares `preinstall: node index.js`, so the payload runs automatically on `npm install` with no user action. index.js requires `os`, `fs`, and `https`, then collects hostname, username, home directory, DNS servers, current working directory, and package metadata, and reads the contents of /etc/passwd and /etc/hosts (index.js:18-19). The aggregated JSON is HTTPS POSTed to `t3x60c96rz2gi7qxftonjplmmdsbg14q.oastify.com`, a Burp Collaborator out-of-band-interaction subdomain controlled by the publisher. Package metadata is empty (author '', description '', ISC license) and the package ships no functional code — it exists solely as an install-time beacon, consistent with a dependency-confusion / pen-test harvest payload.

## What should I do about MAL-2026-6346?

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