## What is MAL-2026-6513?

MAL-2026-6513 is a malicious package in dtxto1ols, published on 26 Jun 2026. 

### Official description

package.json declares a postinstall script that runs automatically on `npm install`. The script performs filesystem reconnaissance (find / -type f scanning for database client binaries such as mysql and mongo, writing results to /data/db_clients_check.txt) and then POSTs the collected file contents over plaintext HTTP to a Burp Collaborator subdomain at 3dhd6wwmusbh04m22igmzvb4hvnmblza.oastify.com. The destination is an out-of-band attacker-controlled collaborator host with no relationship to the package's advertised string-utility purpose. The package name `dtxto1ols` also exhibits a digit-`1` for letter-`l` substitution typical of typosquatting, which corroborates malicious intent.

The OpenSSF Package Analysis project identified 'dtxto1ols' @ 1.0.2 (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-2026-6513?

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