Description

The npm package @cap-js/db-service, a core database service layer for SAP CAP applications, was compromised by a threat actor impersonating SAP maintainers. Malicious code was embedded in the package via a manifest evasion technique that hid a setup script (setup.mjs) from allowlist inspection while still executing it during installation. An anomalously large execution.js file likely contains a payload or exfiltration binary. This compromise affects version 2.10.1 and poses a severe risk to any system with this package installed.

Impact

Any computer with @cap-js/db-service version 2.10.1 installed or running should be considered fully compromised. The malicious code likely grants the attacker full control, risking exposure of all secrets and keys stored on the system. Immediate secret and key rotation from a clean system is required. Removing the package alone may not eliminate all malicious software installed as a result of this compromise.

Defensive guidance

Remove the compromised @cap-js/db-service package version 2.10.1 from all affected systems. Rotate all secrets and keys stored on compromised systems immediately, using a different, trusted computer. Because full system compromise is possible, conduct a thorough investigation and remediation beyond package removal. Monitor for updates or advisories from SAP or the package maintainers regarding patched versions or further guidance.

Summary

The @cap-js/db-service npm package version 2.10.1 was compromised by a threat actor using the email cloudmtabot@gmail.com, impersonating SAP toolchain maintainers. The attacker included malicious files setup.mjs and execution.js in the package tarball, with setup.mjs excluded from the package.json 'files' allowlist to evade detection but still executed via a preinstall hook. The large execution.js file suggests an embedded payload or exfiltration binary. Because @cap-js/db-service is a transitive dependency in most SAP CAP projects, this supply chain compromise has broad potential impact across SAP CAP deployments.
