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 runs a data-collection script. It searches local and CI-related locations, reads environment-related files, and sends the results to an external webhook. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-13T14:38:09.256Z - **Finished:** 2026-09-13T14:38:46.253Z - **Download time:** 508 ms - **Static scan time:** 18 ms - **AI review time:** 36470 ms - **Total time:** 36997 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 runs a data-collection script. It searches local and CI-related locations, reads environment-related files, and sends the results to an external webhook. - **Trigger:** npm installation, through the postinstall lifecycle hook. - **Impact:** Sensitive local, shell, CI, and environment-file contents may be disclosed to a third party. - **Evidence paths:** package.json, exfil\_v3.js - **Review source:** ai\_review - **Reviewed:** 2026-09-13T14:38:46.253Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Install-time file and environment collection followed by HTTPS exfiltration. - **Attack narrative:** On npm installation, package.json launches exfil\_v3.js. The script checks runtime and CI context, searches temporary, home, and workspace directories for files named like flags or payload markers, and reads selected environment-related files. It serializes the collected data and posts it to a fixed webhook.site endpoint. The exported SDK code does not require this behavior, so the automatic lifecycle execution is unrelated to the stated package function. - **Rationale:** This is concrete install-time data collection and exfiltration to a third-party endpoint. The lifecycle hook makes the behavior run without an explicit package API call. - **Files touched:** exfil\_v3.js, /tmp/.icx-runtime, /etc/environment - **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 the collection script during npm installation., The script searches temporary, home, and CI workspace directories for files with sensitive-looking names., The script reads shell and environment files, then posts the collected data to a third-party webhook. - **Evidence against:** The public index entrypoint is a small inert client stub., No legitimate SDK functionality invokes the collection script. ## Affected versions and remediation This report applies to concierge-sdk@99.99.101. - Avoid installing concierge-sdk@99.99.101. 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.
