Malicious package

Published to npm · OSV MAL-2026-10512

What to do

Remove type-unique 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 type-unique version 3.1.3 is malicious. It impersonates the pino logger but executes a detached child process that fetches and runs remote JavaScript code with full Node.js privileges. This remote code execution allows an attacker to run arbitrary code on any system that loads this package. The malicious payload is fetched from unauthenticated third-party JSON hosting services controlled by the attacker. Systems with this package installed should be considered fully compromised, and secrets should be rotated. Removal of the package alone may not eliminate all malicious artifacts.

Impact

Any system that installs or runs type-unique@3.1.3 is fully compromised due to arbitrary remote code execution with full Node.js privileges. Attackers can execute any code, potentially stealing secrets, keys, or further persisting on the system. The unauthenticated and unpinned nature of the payload delivery means attackers can change the malicious code at will. Secrets and keys stored on affected systems should be considered exposed and rotated immediately. Simply removing the package does not guarantee removal of all malicious software installed as a result.

Defensive guidance

The package should be immediately removed from all systems. All secrets and keys on affected machines must be rotated from a secure, uncompromised environment. Due to full system compromise, affected hosts should be considered untrusted and rebuilt if possible. Monitor for any signs of persistence or additional malware installed as a result of this package. Avoid using this package or any versions related to 3.1.3.

Summary

The npm package type-unique@3.1.3 masquerades as the pino logger but, upon require(), spawns a detached Node.js child process that fetches JSON payloads from attacker-controlled third-party hosting services. It extracts a 'cookie' field from the JSON and executes it using the Function constructor, granting full Node.js execution capabilities including access to require. Additional command and control URLs are obfuscated as base64-encoded constants within the package source. The fetched payload is unpinned and unauthenticated, enabling arbitrary remote code execution on any machine that loads this package version. This results in complete compromise of the host system.
