# MAL-2026-6514: Malicious code in dtxtools (npm)


- **Type:** Malicious package
- **Package:** `dtxtools` (npm)
- **Published:** 26 Jun 2026

## What is MAL-2026-6514?

MAL-2026-6514 is a malicious package in dtxtools, published on 26 Jun 2026. 

### Official description

package.json declares a postinstall lifecycle script that auto-executes on `npm install`. The hook performs a recursive filesystem search for database client binaries (mysql, mongo, mongosh, psql, redis-cli, sqlite3, elasticsearch), writes results to /data/db_clients_check.txt, and POSTs the collected output via plain-HTTP curl to `http://3dhd6wwmusbh04m22igmzvb4hvnmblza.oastify.com`, a Burp Collaborator (OAST) subdomain used as an out-of-band attacker channel. The package advertises itself as a string-utility library (index.js header references `easy-string-kit`) and ships benign-looking helper code as a cover; the install-time reconnaissance and exfiltration are unrelated to that advertised purpose. Author, repository, bugs, and homepage fields in package.json are empty, consistent with a disposable decoy publish.

The OpenSSF Package Analysis project identified 'dtxtools' @ 1.0.0 (npm) as malicious.

It is considered malicious because:

- The package communicates with a domain associated with malicious activity.

- The package executes one or more commands associated with malicious behavior.

## What should I do about MAL-2026-6514?
