Description

The npm package @securihackbot/depconf-flow-1792484611 version 1.2.1 contains malicious code that executes automatically upon installation. Its postinstall script collects host metadata including hostname, user environment variables, platform, architecture, Node.js version, package name, and a nonce. This data is base64-encoded and exfiltrated via an unencrypted HTTP GET request to a hardcoded IP address. A DNS-based fallback exfiltration method is also implemented. This behavior occurs without user consent and affects any build host that resolves this public package instead of an intended internal package.

Impact

The impact is unauthorized data exfiltration of potentially sensitive host metadata from build environments that install this package version. This can lead to exposure of internal hostnames, user environment variables, platform details, and other identifying information to an attacker-controlled server. The exfiltration occurs without user consent and over unencrypted channels, increasing the risk of interception or misuse. This compromises the confidentiality of build host environments and may facilitate further targeted attacks or reconnaissance.

Defensive guidance

Users should avoid installing version 1.2.1 of @securihackbot/depconf-flow-1792484611. Review and restrict access to internal package namespaces to prevent dependency confusion attacks. Monitor package sources carefully to ensure that internal packages are not resolved from public registries. Consider network controls to block outbound HTTP requests to suspicious IP addresses such as 34.143.131.27. Since this package executes malicious code on install, avoid using untrusted or unknown packages and audit postinstall scripts in dependencies.

Summary

This threat involves a malicious npm package published under the @securihackbot scope as a dependency confusion attack targeting internal package namespaces. The package's postinstall script runs automatically on npm install, harvesting host identifiers and environment details. It exfiltrates this information in base64-encoded form over plain HTTP to a hardcoded IP address (http://34.143.131.27:18080/). Additionally, it uses a DNS exfiltration fallback by resolving nonce-prefixed subdomains under a configured DNS suffix. The exfiltration occurs silently without any opt-in or authorization checks, potentially leaking sensitive build environment metadata to an attacker-controlled collector. The README's mention of 'authorized research' does not restrict this behavior, making it a covert data exfiltration malware embedded in a public npm package.
