New alerts

Native code

Supply chain risk

Contains native code which could be a vector to obscure malicious code, and generally decrease the likelihood of reproducible or reliable installs.

Found 1 instance in 1 package

New author

Supply chain risk

A new npm collaborator published a version of the package for the first time. New collaborators are usually benign additions to a project, but do indicate a change to the security surface area of a package.

Fixed alerts

Install scripts

Supply chain risk

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