Description

The @marketfront/infopopup npm package version 7.0.0 is part of a malicious campaign involving 25 packages published within a short time frame. It contains a postinstall script that executes heavily obfuscated code to harvest sensitive credential files and environment data from the installer’s system. The stolen data is exfiltrated via encrypted HTTPS POST requests and DNS tunneling to attacker-controlled infrastructure. The package masquerades as an internal authentication client but performs unauthorized credential harvesting and data exfiltration.

Impact

Installation of this package results in unauthorized access and exfiltration of sensitive credential files and environment data from the host system. This can lead to compromise of cloud accounts, source code repositories, container registries, and other critical infrastructure accessed via the stolen credentials. The attacker gains persistent access to sensitive information through encrypted communication channels that evade typical network filtering.

Defensive guidance

Users should avoid installing version 7.0.0 of @marketfront/infopopup and remove it if already installed. Audit systems for presence of this package and related suspicious network activity. Use trusted sources and verify package authenticity before installation. Monitor for similar malicious packages published under the @marketfront npm scope and related scopes. Since this is a malicious package, remediation involves removal and blocking rather than patching.

Summary

The @marketfront/infopopup package (version 7.0.0) was batch-published as part of a malicious campaign on 2026-07-01. It includes a postinstall hook that runs obfuscated code designed to collect sensitive credential files such as SSH keys, AWS credentials, Kubernetes configs, Docker configs, npm credentials, Git credentials, and shell history. The harvested data and environment information are encrypted and exfiltrated via HTTPS POST requests and DNS queries to attacker-controlled domains. The campaign shares infrastructure and tooling with a previous campaign under the @emcd-vue scope, indicating a common threat actor. The package falsely claims to be an internal authentication client and uses fabricated corporate identities as a cover story.
