Description

The npm package mui-wrapper-x-date-pickers versions 1.0.0 and 10.0.0 contains malicious preinstall and postinstall scripts that send the installer's OS username, hostname, and current working directory in plaintext HTTP requests to an untrusted external IP address. The package mimics the naming pattern of a legitimate internal package to exploit dependency confusion. No other code execution or payload is present beyond these data exfiltration requests.

Impact

Installation of the affected package versions results in unauthenticated disclosure of potentially sensitive host identity information (username, hostname, working directory) to an unknown external server over unencrypted HTTP. This can lead to privacy breaches and reconnaissance by an attacker. No direct code execution or system compromise beyond this data leak is indicated.

Defensive guidance

Avoid installing the mui-wrapper-x-date-pickers package versions 1.0.0 and 10.0.0 from untrusted sources. Remove any instances of these versions from your environment. Use strict package version pinning and verify package provenance to prevent dependency confusion attacks.

Summary

The npm package mui-wrapper-x-date-pickers, published by the account amahrou1w, includes preinstall and postinstall lifecycle scripts that perform HTTP GET requests to a hardcoded IP address (38.242.235.206). These requests transmit environment information including the OS username, hostname, and current working directory of the installing machine without encryption or user consent. The package name and versioning appear designed to exploit dependency confusion by resembling an internal package from a known vendor. Static analysis found no further malicious code beyond these data-leaking requests.
