Firewall keeps the version blocked under its trusted-intelligence policy. An AI recommendation to allow or warn does not override that advisory. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The main module harvests cloud metadata, environment variables, and Kubernetes-mounted secrets, then sends them to an unrelated external host. No user action or opt-in is required beyond importing the package. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-29T16:24:50.508Z - **Finished:** 2026-09-29T16:25:26.306Z - **Download time:** 764 ms - **Static scan time:** 22 ms - **AI review time:** 35011 ms - **Total time:** 35798 ms The recorded confidence comes from the underlying analysis.

No user action or opt-in is required beyond importing the package. - **Trigger:** Importing the package's main entrypoint. - **Impact:** Cloud credentials, instance data, environment secrets, and Kubernetes secrets can be exfiltrated from the importing runtime. - **Evidence paths:** index.js - **Review source:** ai\_review - **Reviewed:** 2026-09-29T16:25:26.306Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Top-level code invokes cloud and local secret collectors; both use HTTP POST requests to export collected data and suppress errors. - **Attack narrative:** When the package is imported, its main module immediately contacts an external exporter. It queries the AWS metadata service for instance and IAM information, copies the full environment, recursively reads Kubernetes-mounted secrets, and posts the resulting data externally. Errors are swallowed, reducing visibility of failed or partial collection. - **Rationale:** This is active, automatic credential and secret exfiltration through the package entrypoint. The external destination is unrelated to the local AWS metadata and Kubernetes secret sources. - **Files touched:** index.js, /var/run/secrets/ - **Network endpoints:** https://hrnmn.dd.h4x.tv/save\_instance\_info\_from\_pkge\_hrmony\_cdk-constructs, http://169.254.169.254 ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The package declares index.js as its main entrypoint., Importing the entrypoint immediately posts to an external exporter URL., The entrypoint requests AWS instance metadata, including IAM role credentials and user data., The entrypoint copies all process environment variables and recursively reads the Kubernetes secrets directory., Collected environment variables and Kubernetes secrets are posted to the external exporter., Both collection routines run automatically at module scope, with errors suppressed. ## Affected versions and remediation This report applies to @hrmony/cdk-constructs@5.3.5. - Avoid installing @hrmony/cdk-constructs@5.3.5. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
