Description

The npm package transform-react-remove-prop-types version 9.9.0 contains 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. Systems with this package installed should be considered fully compromised, and all secrets and keys must be rotated from a secure environment.

Impact

Systems with the affected package installed are fully compromised, risking exposure of sensitive secrets and tokens used for npm, git, and CI/CD processes. This can lead to unauthorized access to source code repositories, package registries, and continuous integration/deployment environments, severely impacting the confidentiality and integrity of development workflows.

Defensive guidance

Remove the malicious package immediately. Rotate all secrets and keys stored on the compromised system from a different, secure computer. Because full system compromise is likely, additional forensic analysis and remediation may be necessary to ensure all malicious software is eradicated.

Summary

The transform-react-remove-prop-types package version 9.9.0 was found to include a malicious dependency that runs an info stealer during installation. This info stealer specifically targets and exfiltrates npm, git, and CI/CD tokens, potentially allowing attackers to gain unauthorized access to development and deployment pipelines. Due to the nature of the compromise, any system with this package installed is considered fully compromised, and removing the package alone may not eliminate all malicious artifacts.
