Reporting malware in an npm package
See Details
Table of contents
If you find malware in an npm package (either yours or someone else's), you can report it to the npm Security team to help keep the Javascript ecosystem safe.
Note: Vulnerabilities in npm packages should be reported directly to the package maintainers. We strongly advise doing this privately. You can find contact information about package maintainers with npm owner ls <package-name>. If the source code is hosted on GitHub please refer to the repository's Security Policy.
How npm Security handles malware
Malware is a major concern for npm Security and we have removed hundreds of malicious packages from the registry. For every malware report we receive, npm Security takes the following actions:
- Confirm validity of the report.
- Remove the package from the registry.
- Publish a security placeholder for the package.
- Publish a security advisory alerting the community.
As part of our process we determine whether the user account who uploaded the package should be banned. We also cooperate with 3rd parties when applicable.
