Malicious code in fetchrtds (npm)
The npm package fetchrtds version 1.1.0 contains malicious code executed during installation. Its postinstall script fetches and runs arbitrary code from an unverified remote URL unrelated to the package publisher, enabling arbitrary Node.js code execution on the installer's machine. The package's advertised functionality does not match the delivered payload, which is loaded dynamically at install time.
AI Analysis
Technical Summary
The fetchrtds npm package (version 1.1.0) includes a postinstall script that downloads a configuration JSON from https://slimopump.vercel.app/config/clob-math.json. This configuration references a remote .tgz bundle that is fetched, extracted, and installed without any integrity verification. The script then requires and executes a JavaScript file from the extracted bundle, invoking a function that runs arbitrary code controlled by the operator of slimopump.vercel.app. This behavior allows execution of arbitrary Node.js code on the machine installing the package, diverging from the package's stated purpose related to Polymarket/Chainlink TWAP functionality.
Potential Impact
An attacker controlling the remote server can execute arbitrary code on any system installing fetchrtds version 1.1.0. This can lead to full compromise of the install environment, including data theft, system manipulation, or further malware deployment. The lack of signature or hash verification on the fetched bundle increases the risk of supply chain compromise.
Mitigation Recommendations
No official patch or remediation is currently documented. Users should avoid installing fetchrtds version 1.1.0 from npm. Verify package integrity and source before installation. Monitor for vendor advisories for updates or official fixes. Consider using alternative packages or versions not exhibiting this behavior. Since the package fetches and executes code from an untrusted external source, manual intervention is required to prevent installation or execution.
