Description

The npm package 'syntax-dynamic-import' version 10.0.0 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. 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 secure machine. Removing the package alone may not eliminate all malicious software introduced.

Impact

Systems with 'syntax-dynamic-import' version 10.0.0 installed are at high risk of credential theft, including npm, git, and CI/CD tokens. This can lead to unauthorized access to repositories, deployment pipelines, and other critical infrastructure. The compromise is considered total, implying that attackers may have full control over the affected system.

Defensive guidance

Remove the 'syntax-dynamic-import' package version 10.0.0 immediately. Rotate all secrets and keys that were stored or used on the compromised system from a different, secure machine. Because the system may be fully compromised, additional forensic analysis and remediation steps should be undertaken to ensure no residual malicious software remains.

Summary

The 'syntax-dynamic-import' npm package version 10.0.0 was found to include a malicious dependency hosted on a custom domain. During installation, this dependency runs an info stealer that specifically targets npm, git, and CI/CD tokens, potentially exposing sensitive credentials. The compromise is severe enough that affected systems should be treated as fully compromised, requiring immediate secret rotation and comprehensive remediation beyond just uninstalling the package.
