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. An automatic install hook exports identifying host and project information to a fixed external endpoint. This behavior is unrelated to the package's text-formatting function. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-30T07:05:09.390Z - **Finished:** 2026-09-30T07:06:09.834Z - **Download time:** 513 ms - **Static scan time:** 11 ms - **AI review time:** 59920 ms - **Total time:** 60444 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:** An automatic install hook exports identifying host and project information to a fixed external endpoint. This behavior is unrelated to the package's text-formatting function. - **Trigger:** npm installation activates the preinstall hook. - **Impact:** Exposes the installing user's identity, hostname, project location and environment details to the endpoint operator. - **Evidence paths:** package.json, setup.js - **Review source:** ai\_review - **Reviewed:** 2026-09-30T07:06:09.834Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** setup.js collects local environment metadata, serializes it and sends it through an HTTPS POST without a consent gate. - **Attack narrative:** Installing the package automatically executes setup.js. The script gathers identifying machine and project metadata and transmits it to a fixed AWS API Gateway endpoint. Both the lifecycle command and request handlers suppress failures, allowing installation to continue quietly. The export has no functional connection to the runtime text-capitalization utility. - **Rationale:** The source proves automatic, unconsented export of local identifying information to an unrelated external recipient. This concrete install-time data exfiltration warrants blocking. - **Network endpoints:** https://s85r5k14qk.execute-api.us-east-1.amazonaws.com/prod/hook ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** package.json automatically runs setup.js during preinstall and suppresses failure., setup.js collects hostname, username, working directory, platform, architecture, Node version and registry configuration., setup.js sends the collected data by HTTPS POST to an unrelated fixed endpoint., setup.js writes the payload and silently handles request errors; no consent gate exists. - **Evidence against:** The runtime entrypoint only implements text capitalization., No credential theft, destructive writes or persistence was found. ## Affected versions and remediation This report applies to alexa-cybertron-team-code-review-agent@100.0.0. - Avoid installing alexa-cybertron-team-code-review-agent@100.0.0. 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.
