Malicious package

Published to npm · OSV MAL-2026-6771

What to do

Remove @marketfront/commonecommerce from every project, lockfile and image that pulls it in. Treat any host that installed it as compromised: rotate the credentials, tokens and keys it could read, from a clean machine.

Description

The @marketfront/commonecommerce npm package version 7.0.0 is part of a malicious campaign involving 25 packages published within a short time frame. It contains a heavily obfuscated postinstall script that executes automatically during npm install, harvesting sensitive credentials and environment data from the host. The stolen data includes SSH keys, AWS credentials, Kubernetes configs, Docker configs, npm and git credentials, environment files, and shell history. Exfiltration occurs via encrypted HTTPS POST requests and covert DNS tunneling to a concealed command-and-control server. The package masquerades as a legitimate telemetry client for a non-existent organization, with a non-functional advertised API. No patch or remediation is currently documented.

Impact

If installed, this package compromises the host by stealing a broad range of sensitive credentials and environment information, including SSH keys, cloud service credentials, Kubernetes and Docker configs, npm and git credentials, and shell history. This data exfiltration can lead to unauthorized access to cloud resources, source code repositories, and other critical infrastructure. The use of covert DNS tunneling alongside HTTPS exfiltration increases the likelihood of bypassing network security controls. The malicious code executes automatically at install time without user interaction, increasing the risk of widespread compromise in development environments that inadvertently install this package.

Defensive guidance

Until an official fix or removal is published, users should avoid installing or updating to version 7.0.0 of @marketfront/commonecommerce. Audit existing environments for the presence of this package and remove it if found. Consider blocking the @marketfront npm scope in internal package registries and monitoring for suspicious postinstall scripts in dependencies. Due to the malicious nature of the package, no legitimate use is expected, so removal is the safest course of action.

Summary

This threat involves a malicious npm package, @marketfront/commonecommerce version 7.0.0, published as part of a 25-package campaign under the @marketfront scope. The package uses a postinstall lifecycle hook to run a 162 KB obfuscated JavaScript payload that harvests a wide range of sensitive credential files and environment variables from the infected system. The harvested data is encrypted with RC4 and exfiltrated via two channels: an HTTPS POST to a dynamically assembled host and DNS-label tunneling designed to evade egress filtering. The package attempts to evade detection by inspecting runtime arguments and environment variables and delaying execution. It falsely claims to be a telemetry client for a legitimate organization, which does not exist. The actual library code is a stub, with the postinstall script being the only active malicious component. This campaign shares infrastructure and tooling with a previous campaign, indicating a persistent threat actor rotating npm scopes and maintainer identities.
