# MAL-2026-4664: Malicious code in search-connector-template (npm)


- **Type:** Malicious package
- **Package:** `search-connector-template` (npm)
- **Published:** 21 May 2026

## What is MAL-2026-4664?

MAL-2026-4664 is a malicious package in search-connector-template, published on 21 May 2026. 

### Official description

package.json declares `preinstall: node index.js`, which fires automatically on `npm install`. index.js collects host identity (hostname, username, homedir, DNS servers) and reads installer-owned system files (/etc/passwd, /etc/hosts), then POSTs the JSON payload over HTTPS to a Burp Collaborator OAST subdomain (`615arnt4a5f6ii011q8kggqfk6q1er2g.oastify.com`). This is a classic install-time exfiltration beacon: the destination is attacker-controlled, the data leaving the host belongs to the installer rather than the package author, and execution requires no user action beyond running `npm install`.

## What should I do about MAL-2026-4664?

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