Malicious package

Published to npm · OSV MAL-2026-5648

What to do

Remove unified-ui-components-library 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

--- _-= Per source details. Do not edit below this line.=-_ ## Source: amazon-inspector (78fe6900f4329c8e4c7bb5322f0e30a3f3b90e289c45852fca61c4fd16f43fd8) On `npm install`, the package's postinstall.js collects `os.hostname()` and `os.userInfo().username` and embeds them as query-string parameters in a plaintext HTTP GET to a hardcoded bare IP (http://161.97.149.48/skybackground.png?display=<hostname>&profile=<username>). The fetch is dressed up as an 'image download' but the identifying data is in the URL the server logs, giving the operator a per-install fingerprint of every machine that installs the package. The download path also follows 301/302 redirects to attacker-chosen Locations and writes the server's response body to./downloaded-image.jpg with no content-type validation, providing staging infrastructure alongside the beacon. Cover-story signals corroborate intent: package.json describes an 'image downloader CLI' with placeholder author 'Your Name', README.md advertises an unrelated 'Simple Text Utils' API (capitalize/reverse/wordCount) that the code does not implement, and index.js exports only `downloadImage`. The advertised purpose, README, and shipped code disagree — the consistent behavior across all three is the install-time phone-home. ## Source: ghsa-malware (32a71bf0eee8d7fd2046101d3e1aea109e28f965a3ec4ddcdf9627dd1aecf5a4) Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.

Impact

Installation of the affected package versions results in disclosure of machine hostname and user information to an attacker-controlled server. The attacker can log each installation uniquely and stage additional malicious payloads on the compromised system by downloading arbitrary files without validation. This compromises the confidentiality and integrity of the affected system. The advisory states that any computer with this package installed should be considered fully compromised, and all secrets and keys on the system should be rotated immediately from a different machine.

Defensive guidance

Remove the affected package versions (10.0.1, 10.0.2, 10.0.3) immediately from all systems. Rotate all secrets, credentials, and keys that were stored or used on the compromised machines from a secure, unaffected environment. Because the package grants potential full control to an attacker, assume the system is fully compromised and consider rebuilding or thoroughly investigating for persistence mechanisms. Patch status is not applicable as this is a malicious package rather than a vulnerability with a vendor fix.

Summary

The unified-ui-components-library npm package (versions 10.0.1, 10.0.2, and 10.0.3) includes a postinstall script that collects system identifiers (hostname and username) and sends them in plaintext via an HTTP GET request to a hardcoded IP address. This request masquerades as an image download but serves as a beacon to the attacker, logging identifying information of each installation. Additionally, the package follows HTTP redirects to attacker-controlled locations and writes the response body to a local file without validating content type, enabling staging of malicious payloads. The package's metadata and README misrepresent its functionality, consistent with malicious intent. The presence of this package indicates a full system compromise.
