Description
The iot-cardboard-js npm package versions 9.9.0 and 9.9.1 contain malicious code that installs a dependency from a custom domain which executes an information stealer during installation. This malware targets sensitive tokens related to npm, git, and CI/CD environments. Any system with this package installed should be considered fully compromised, and all secrets and keys stored on that system must be rotated immediately from a separate, secure machine. Removing the package alone may not eliminate all malicious components due to potential full system compromise.
