What to do

Remove @an1mshnpmb9c84920/pipe-dns-m19t2 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 npm package @an1mshnpmb9c84920/pipe-dns-m19t2 contains malicious code embedded in its package.json metadata. Specifically, the repository.url field includes a shell command substitution that triggers a DNS lookup to an attacker-controlled domain, leaking the installer's host identity. The package itself has no legitimate functionality and appears to be part of a dependency confusion or manifest injection attack targeting internal npm tooling. Installation of this package compromises the host, potentially exposing all stored secrets and keys.

Impact

Any system that installs or runs this package is considered fully compromised. The malicious payload leaks the host identity via DNS to an attacker-controlled server, potentially enabling further targeted attacks. Because the package grants an attacker control over the host environment, all secrets and keys stored on the compromised machine should be considered exposed and must be rotated immediately. Removing the package alone does not guarantee removal of all malicious artifacts or backdoors introduced by the attacker.

Defensive guidance

Remove the malicious package immediately from all affected systems. Rotate all secrets, keys, and credentials stored on compromised machines from a separate, trusted environment. Since the package grants full control to an attacker, assume the system is compromised and conduct a thorough incident response and forensic analysis.

Summary

This threat involves a malicious npm package named @an1mshnpmb9c84920/pipe-dns-m19t2. The package.json file contains a crafted repository.url field embedding a shell command substitution payload that executes when tooling interpolates this field in a shell context. The payload performs a DNS query to an attacker-controlled subdomain under oob.awss.dev, leaking the host's identity to the attacker. The package body is a minimal stub with no legitimate code, indicating the attack vector is through metadata exploitation. This behavior aligns with dependency confusion or manifest injection probes aimed at internal npm tooling environments. The package versions 1.0.0, 1.0.1, and 1.0.5 are affected.
