Malicious code in notafollower122 (npm)
The npm package 'notafollower122' contains malicious code in its postinstall script that executes automatically during installation. This script collects AWS ECS container metadata from the installer's environment and exfiltrates it to an anonymous ngrok tunnel. The package lacks any legitimate source code or documented functionality, indicating the postinstall script serves no valid purpose other than reconnaissance and data exfiltration. Multiple versions of the package (1.0.0 through 1.0.7) are affected.
AI Analysis
Technical Summary
The 'notafollower122' npm package includes a postinstall lifecycle script that runs automatically on 'npm install'. This script uses Node.js child_process to query the AWS ECS container metadata endpoint (ECS_CONTAINER_METADATA_URI_V4/task), retrieving sensitive information such as cluster name, AWS account ID, task ARN, and container image list. It then sends this data via a POST request to a hardcoded, anonymous ngrok tunnel URL. The package contains only a package.json file without source code or build artifacts, confirming the postinstall script's malicious intent for cloud environment reconnaissance and exfiltration targeting AWS ECS environments.
Potential Impact
Installation of affected versions of the 'notafollower122' package results in unauthorized disclosure of AWS ECS container metadata to an attacker-controlled endpoint. This leakage can expose sensitive cloud environment details, potentially aiding further attacks or reconnaissance. There is no indication of active exploitation in the wild at this time.
Mitigation Recommendations
No official patch or remediation is currently documented. Users should avoid installing the 'notafollower122' package in any version. Review and remove any installations of this package from your environments. Monitor package sources carefully to prevent inclusion of malicious packages. Patch status is not yet confirmed — check the vendor advisory or trusted security sources for updates.
