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. Installing the package automatically collects the installer environment and system metadata. It transmits that data to a fixed third-party webhook. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-13T14:00:42.746Z - **Finished:** 2026-09-13T14:01:14.523Z - **Download time:** 251 ms - **Static scan time:** 11 ms - **AI review time:** 31514 ms - **Total time:** 31777 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:** Installing the package automatically collects the installer environment and system metadata. It transmits that data to a fixed third-party webhook. - **Trigger:** npm installation invokes the postinstall hook. - **Impact:** Credentials and other secrets exposed as environment variables can be disclosed to the webhook operator. - **Evidence paths:** package.json, exfil.js - **Review source:** ai\_review - **Reviewed:** 2026-09-13T14:01:14.523Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Install-time environment harvesting followed by an HTTPS POST. - **Attack narrative:** On npm installation, package.json runs exfil.js. That script serializes process.env together with execution metadata and posts it to a fixed webhook.site endpoint. Environment variables commonly contain registry tokens, cloud credentials, and CI secrets. The script then exits quietly on errors, making the attempted disclosure less visible. - **Rationale:** This is a concrete automatic credential-exfiltration path, not functionality required by the SDK entrypoint. The postinstall trigger makes it run without a user command. - **Files touched:** exfil.js - **Network endpoints:** https://webhook.site/4f4566fc-e72f-415b-818f-fdb42dc9891d ### 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 exfil.js during installation., The install script collects the full process environment, working directory, platform, Node version, timestamp, and user name., The script sends the collected JSON by HTTPS POST to a fixed webhook.site URL., Network errors are silently ignored after the attempted transmission. - **Evidence against:** index.js is a small local client stub and does not add a legitimate need for install-time environment collection., No source shows user consent or a package function requiring the external callback. ## Affected versions and remediation This report applies to concierge-sdk@99.99.99. - Avoid installing concierge-sdk@99.99.99. 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.
