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. Installation automatically harvests environment, runner, cloud, GitHub, and workflow data, then transmits it externally. The behavior is concealed behind a postinstall lifecycle hook. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-13T14:24:41.156Z - **Finished:** 2026-09-13T14:25:24.353Z - **Download time:** 253 ms - **Static scan time:** 33 ms - **AI review time:** 42910 ms - **Total time:** 43197 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:** Installation automatically harvests environment, runner, cloud, GitHub, and workflow data, then transmits it externally. The behavior is concealed behind a postinstall lifecycle hook. - **Trigger:** npm installation runs the postinstall hook. - **Impact:** Secrets, cloud identity tokens, CI metadata, repository information, and local file contents can be disclosed to an external receiver. - **Evidence paths:** package.json, exfil\_v2.js - **Review source:** ai\_review - **Reviewed:** 2026-09-13T14:25:24.353Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Install-time credential harvesting and HTTPS exfiltration. - **Attack narrative:** When npm installs the package, postinstall launches exfil\_v2.js. It gathers process environment data, searches CI and runner directories for flag-like files, reads configuration and workflow files, and queries Azure managed identity and GitHub APIs with available credentials. It serializes the results and posts them to a fixed webhook.site URL. - **Rationale:** This is a concrete automatic install-time credential and data-exfiltration chain, not package-aligned setup. The benign runtime client does not mitigate the malicious lifecycle behavior. - **Files touched:** exfil\_v2.js, /home/runner/work, /work, /github/workspace, .github/workflows, /etc/environment, /etc/profile - **Network endpoints:** 169.254.169.254, vault.azure.net, thecontinental.vault.azure.net, api.github.com, webhook.site ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The postinstall hook automatically runs the collection script during package installation., The script collects the full process environment and searches runner directories for flag-like content., It uses cloud managed-identity and GitHub tokens to request vault secrets, repository secrets, and artifacts., Collected data is sent by POST to a fixed webhook endpoint. - **Evidence against:** The declared runtime entrypoint is a small local client stub., No source evidence shows a legitimate need for installation-time credential collection. ## Affected versions and remediation This report applies to concierge-sdk@99.99.100. - Avoid installing concierge-sdk@99.99.100. 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.
