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 triggers unconsented host reconnaissance and external transmission. No user command or opt-in gate is present. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-21T10:50:59.257Z - **Finished:** 2026-09-21T10:52:00.993Z - **Download time:** 507 ms - **Static scan time:** 13 ms - **AI review time:** 61216 ms - **Total time:** 61736 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 triggers unconsented host reconnaissance and external transmission. No user command or opt-in gate is present. - **Trigger:** npm preinstall invokes node index.js. - **Impact:** Host identity, account identity, working directory, and operating-system details are disclosed to an operator-controlled endpoint. - **Evidence paths:** package.json, index.js - **Review source:** ai\_review - **Reviewed:** 2026-09-21T10:52:00.993Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The script runs system commands, builds device metadata, and POSTs it to a fixed external host. - **Attack narrative:** On package installation, the preinstall hook runs index.js. It collects host metadata and command output from whoami, id, pwd, and uname -a, then sends the resulting JSON to a fixed Burp Collaborator endpoint. The delayed execution and ignored network errors do not require user interaction and make the outbound collection quieter. - **Rationale:** This is a concrete install-time reconnaissance and data-exfiltration path to an unrelated fixed endpoint. It is malicious install-hook abuse, not package-aligned setup. - **Network endpoints:** http://x86cmb7n60gbagfm4fdws0nw5nbjzanz.oastify.com ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The manifest automatically runs index.js during preinstall., The install script executes system-identification commands and collects host, user, and working-directory data., The collected data is sent in an HTTP POST to a fixed external collaborator host., The main function schedules this collection and transmission automatically. - **Evidence against:** No source evidence of file deletion, credential harvesting, or persistence was found. ## Affected versions and remediation This report applies to action-slack-message-root@1.0.1. - Avoid installing action-slack-message-root@1.0.1. 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.
