New Malicious CVE NOT AVAILABLE CWE-506 (opens in a new tab)How to fix?
Avoid using all malicious instances of the typescript-react-query package.
Overview
typescript-react-query is a malicious package. This package was recognized as part of the 'PhantomRaven' supply chain campaign, which involves credential-stealing malware. The package impersonates well-known ecosystem plugins to deceive developers into installing it.
Malicious Behavior
The package uses Remote Dynamic Dependencies (RDD) to avoid detection. Instead of embedding malicious code directly into the npm registry, its package.json lists an external URL as a dependency. During a regular npm install, npm quietly downloads and runs a secondary payload from an attacker-controlled server. After execution, the malware collects and sends sensitive data, including developer email addresses from .gitconfig and .npmrc files, system fingerprints, and CI/CD tokens.
