Description

--- _-= Per source details. Do not edit below this line.=-_ ## Source: amazon-inspector (cadcdda902675162dd9cfabd9d8133986723d4c956437633f36a5a07b776ef59) [email protected] ships an empty stub (index.js: `module.exports = {};`) with no description, author, or repository, but declares a single dependency `ltidisafe` as a direct tarball URL: `https://ltidi.storage.googleapis.com/depenconf/ltidisafe-3.0.6.tgz`. The bucket is on Google Cloud Storage, unrelated to any documented publisher, and the bucket/path naming (`ltidi`/`depenconf`) is consistent with a dependency-confusion staging area. URL-tarball dependencies bypass the npm registry's visibility, signature, and tooling — `npm install` will fetch the.tgz directly and execute any preinstall/install/postinstall lifecycle scripts it ships, with no hash pin, no signature, and no registry review. The wrapper contributes no functionality; its only effect on install is to smuggle the off-registry tarball into the installer's dependency tree. The high version number (99.9.1) and absent metadata are also consistent with a dependency-confusion lure intended to outrank an internal package of the same name. ## Source: ghsa-malware (618392bced7b75db7d804281a68124e3827f13da40512505dfadb7984878d722) 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. ## Source: ossf-package-analysis (783cf770777fff7cfffc2abec6cebd37f9e11f9e219c95e9879dda1222f9177c) The OpenSSF Package Analysis project identified 'firefly-utilities-helper' @ 99.9.1 (npm) as malicious. It is considered malicious because: - The package communicates with a domain associated with malicious activity.

Technical Analysis

The 'firefly-utilities-helper' npm package at version 99.9.1 is malicious. It ships as an empty stub but declares a direct tarball URL dependency to a suspicious off-registry package hosted on Google Cloud Storage. This off-registry dependency bypasses npm registry visibility, signature verification, and tooling, allowing execution of arbitrary lifecycle scripts during installation. The package metadata is absent, and the version number is unusually high, consistent with dependency confusion attacks aiming to outrank legitimate internal packages. The package communicates with domains linked to malicious activity. Removal alone may not fully remediate a compromised system.

Potential Impact

Systems with 'firefly-utilities-helper' version 99.9.1 installed are considered fully compromised. The malicious package can execute arbitrary code during installation, potentially allowing attackers full control over the affected system. All secrets and keys stored on the compromised system should be considered exposed and must be rotated from a secure environment. Simply removing the package does not guarantee removal of all malicious artifacts or backdoors introduced by the package.

Mitigation Recommendations

No official patch or fix is available. The package 'firefly-utilities-helper' version 99.9.1 should be immediately removed from all systems. All secrets and credentials stored on affected systems must be rotated from a different, uncompromised environment. Users should avoid installing packages that declare dependencies via direct tarball URLs from untrusted sources, especially those bypassing the npm registry. Monitor for any signs of compromise and consider rebuilding affected systems to ensure full remediation.
