What is an install script?

Install scripts are run when the package is installed. The majority of malware in npm is hidden in install scripts.

Packages should not be running non-essential scripts during install and there are often solutions to problems people solve with install scripts that can be run at publish time instead.

What are git dependencies?

Contains a dependency which resolves to a remote git URL. Dependencies fetched from git URLs are not immutable can be used to inject untrusted code or reduce the likelihood of a reproducible install.

Publish the git dependency to npm or a private package repository and consume it from there.

Take a deeper look at the dependency

Take a moment to review the security alert above. Review the linked package source code to understand the potential risk. Ensure the package is not malicious before proceeding. If you're unsure how to proceed, reach out to your security team or ask the Socket team for help at support [AT] socket [DOT] dev.

Remove the package

If you happen to install a dependency that Socket reports as Known Malware you should immediately remove it and select a different dependency. For other alert types, you may may wish to investigate alternative packages or consider if there are other ways to mitigate the specific risk posed by the dependency.

Mark a package as acceptable risk

To ignore an alert, reply with a comment starting with @SocketSecurity ignore followed by a space separated list of ecosystem/package-name@version specifiers. e.g. @SocketSecurity ignore npm/foo@1.0.0 or ignore all packages with @SocketSecurity ignore-all

• @SocketSecurity ignore npm/cypress@12.8.1
• @SocketSecurity ignore npm/core-js@3.29.1
• @SocketSecurity ignore npm/eth-sig-util@1.4.2
