Description

The npm package 'dtxto1ols' version 1.0.2 is identified as malicious. It contains a postinstall script that executes automatically during installation, performing filesystem reconnaissance to locate database client binaries and sending collected data in plaintext to an attacker-controlled external domain. The package name uses a digit-1 in place of the letter-l, indicating typosquatting. This behavior is unrelated to the package's advertised utility and is considered malicious.

Impact

Installation of this package results in unauthorized reconnaissance of the host filesystem and exfiltration of potentially sensitive information about installed database clients to an attacker-controlled server. This compromises confidentiality and may facilitate further attacks. The malicious behavior occurs automatically on installation without user consent.

Defensive guidance

Avoid installing the 'dtxto1ols' package version 1.0.2. Remove it from any systems where it is installed. Monitor for and block network communications to the identified malicious domain. Check vendor advisories or npm security advisories for updates or removal notices.

Summary

The 'dtxto1ols' npm package version 1.0.2 includes a postinstall script that scans the filesystem for database client binaries such as MySQL and MongoDB, writing the findings to a local file. It then exfiltrates this data via an HTTP POST request to a Burp Collaborator domain controlled by an attacker. The package name's use of a digit-1 instead of the letter-l suggests typosquatting to deceive users. The OpenSSF Package Analysis project and Amazon Inspector have flagged this package as malicious due to its unauthorized data collection and communication with a malicious domain.
