Description

The npm package @rclaude/darwin-arm64 version 0.2.0 contains malicious code that can fully compromise any computer on which it is installed or running. This compromise includes potential unauthorized access to all secrets and keys stored on the affected system. Immediate removal of the package is advised, but due to the extent of control potentially granted to attackers, complete remediation may require rotating all secrets and keys from a separate, uncompromised device.

Impact

Full system compromise on any computer with the package installed or running. All secrets and keys stored on the compromised system are at risk and should be considered exposed. The attacker may maintain persistent control beyond the presence of the malicious package itself.

Defensive guidance

Remove the @rclaude/darwin-arm64 package version 0.2.0 immediately from affected systems. Rotate all secrets and keys stored on the compromised computer using a separate, secure device. Due to the potential for persistent control, further forensic analysis and system restoration may be necessary to ensure complete remediation.

Summary

The npm package @rclaude/darwin-arm64 version 0.2.0 has been identified as containing malicious code capable of fully compromising the host computer. Installation or execution of this package may allow attackers to gain full control over the system, including access to stored secrets and keys. The package should be removed promptly; however, because the attacker may have established persistent control, simply removing the package does not guarantee elimination of all malicious components. Secrets and keys must be rotated immediately from a different, secure computer to mitigate ongoing risk.
