Description
The transform-es2015-modules-commonjs npm package version 7.9.0 contains malicious code that installs a dependency from a custom domain which executes an information stealer during installation.

Systems with this package installed should be considered fully compromised, and all secrets and keys must be rotated from a secure device. Removing the package alone does not guarantee removal of all malicious software.
