MAL-2026-6513 Malicious code in dtxto1ols (npm)

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.
