Description

--- _-= Per source details. Do not edit below this line.=-_ ## Source: amazon-inspector (85a6f04cbf0697b6ae409fb9e5ad0e25812dac6a2f43bd95722f1903ee2f71f7) Package name `babel-eslint-parser-legacy` is a one-suffix confusion against the legitimate `babel-eslint-parser`. The package's own `main` is an empty stub, so it provides no functionality of its own. Its `package.json` declares a single runtime dependency `ltidisafe` pointing at a direct HTTPS tarball URL — `https://ltidi.storage.googleapis.com/depenconf/ltidisafe-3.1.8.tgz` — hosted on a Google Cloud Storage bucket unaffiliated with Babel and outside the npm registry. On `npm install`, npm fetches and installs the contents of that tarball into the installer's `node_modules`, executing any lifecycle scripts it declares. The tarball bytes are attacker-mutable (the bucket owner can swap contents at any time), are not subject to npm registry scanning, and are not pinned by integrity hash in the manifest. The typosquat name is the lure; the external-URL dependency is the smuggling vector for arbitrary attacker-controlled code into the installer's dependency tree. ## Source: ghsa-malware (94a62a47f0ac7d635081419dfabf152aa8965f114250a5f9dada6079bf432680) 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.

Technical Analysis

The 'babel-eslint-parser-legacy' package is a typosquatting malicious package that exploits npm's ability to install dependencies from external URLs without integrity verification. Its 'package.json' points to a runtime dependency 'ltidisafe' hosted on a Google Cloud Storage bucket unrelated to the legitimate Babel project. This tarball is attacker-controlled and mutable, allowing arbitrary code execution during 'npm install' lifecycle scripts. The package itself is a stub with no functionality, serving solely as a vector to smuggle malicious code into the installer's dependency tree. Any system with this package installed is considered fully compromised.

Potential Impact

Installation of this package results in arbitrary attacker-controlled code execution on the host system due to the untrusted external dependency. This can lead to full system compromise, including theft or manipulation of secrets and keys. The malicious code can persist beyond package removal, making remediation difficult without full system recovery.

Mitigation Recommendations

No official patch or fix is available. The package should be immediately removed from all systems. All secrets and keys stored on affected systems must be rotated from a secure, uncompromised environment. Due to the potential for full system compromise, consider rebuilding or thoroughly cleaning affected systems. Avoid installing packages from untrusted or typosquatting sources and verify package authenticity before installation.
