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. A post-install hook performs host reconnaissance, reads sensitive local data, probes internal services, and exports results to an external server. This is an active installation-time attack surface. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-22T19:34:39.776Z - **Finished:** 2026-09-22T19:35:27.655Z - **Download time:** 252 ms - **Static scan time:** 29 ms - **AI review time:** 47598 ms - **Total time:** 47879 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** A post-install hook performs host reconnaissance, reads sensitive local data, probes internal services, and exports results to an external server. This is an active installation-time attack surface. - **Trigger:** npm installation triggers the postinstall script. - **Impact:** It can expose environment data, SSH material, Kubernetes credentials, n8n configuration, and accessible internal-service data to an external operator. - **Evidence paths:** package.json, postinstall.js - **Review source:** ai\_review - **Reviewed:** 2026-09-22T19:35:27.655Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The script executes shell commands, queries Redis and etcd, scans internal ports, and POSTs collected results to its hard-coded endpoint. - **Attack narrative:** On npm installation, the postinstall hook gathers system and credential-related information, searches reachable Redis and etcd services, scans internal network targets, and sends results to a hard-coded external IP. This behavior is unrelated to data-transformation utilities and creates immediate credential and infrastructure-data exposure. - **Rationale:** The automatic lifecycle hook combines credential harvesting, internal reconnaissance, service-data collection, and exfiltration to an unrelated hard-coded endpoint. This is concrete malicious installation-time behavior. - **Files touched:** /etc/resolv.conf, /etc/hosts, $HOME/.ssh/id\_\*, $HOME/.ssh/authorized\_keys, /var/run/secrets/kubernetes.io/serviceaccount/token, /home/node/.n8n/config, ~/.n8n/config - **Network endpoints:** 193.149.176.186:8888/lombard/n8n-rce, 100.72.158.36:6379, 172.18.0.1:6379, 172.18.0.1:2379 ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The package automatically runs postinstall.js when installed., The installer collects environment, SSH-key, Kubernetes-token, n8n-configuration, and host information through shell commands., Collected data is POSTed to a hard-coded external IP address., The installer probes Redis and etcd services and sends Redis keys and values to that endpoint., It scans internal addresses and ports during installation. ## Affected versions and remediation This report applies to n8n-nodes-data-transformer-utils@1.0.0. - Avoid installing n8n-nodes-data-transformer-utils@1.0.0. 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.
