Description

The @marketfront/fashiononboardingpopup 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 automatically during npm install, running heavily obfuscated code that harvests sensitive credential files from the host system. The stolen data is compressed and exfiltrated via HTTPS POST requests to a concealed command-and-control server. The package's functional code is a stub, designed to appear as an internal private package to evade suspicion. The campaign shares characteristics with a previous malicious campaign, indicating a recurring threat actor.

Impact

Systems that install @marketfront/fashiononboardingpopup version 7.0.0 are at risk of having sensitive credential files and environment information harvested and exfiltrated to a remote attacker-controlled server. This can lead to credential compromise, unauthorized access to cloud services, source code repositories, container registries, and other sensitive infrastructure. The malicious postinstall script executes automatically without user consent during npm install, increasing the risk of silent compromise in development or deployment environments.

Defensive guidance

Users should immediately avoid installing @marketfront/fashiononboardingpopup version 7.0.0 and remove it from existing environments. Audit and rotate any potentially exposed credentials and secrets that may have been compromised. Use trusted package sources and verify package integrity before installation. Monitor for any suspicious network activity related to exfiltration endpoints described. Since this is a malicious package published on npm, remediation involves removing the package and credentials rather than applying a patch.

Summary

The @marketfront/fashiononboardingpopup package at version 7.0.0 includes a postinstall hook executing obfuscated code that collects extensive host system information and sensitive credential files such as SSH keys, AWS credentials, Kubernetes configs, Docker configs, npm credentials, and environment files. This data is encrypted and exfiltrated to a remote server via HTTPS POST requests with custom headers. The payload includes anti-analysis techniques to evade detection during debugging or analysis. The package's main code is a non-functional stub, serving as a cover for the malicious payload. This package is part of a coordinated campaign of 25 malicious packages published under the @marketfront npm scope, sharing infrastructure and tooling with a previous campaign targeting npm users.
