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 contacts an external host with local account and host identifiers. This is an unconsented install-time data-exfiltration callback. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-14T03:36:54.770Z - **Finished:** 2026-09-14T03:37:16.977Z - **Download time:** 517 ms - **Static scan time:** 22 ms - **AI review time:** 21667 ms - **Total time:** 22207 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 contacts an external host with local account and host identifiers. This is an unconsented install-time data-exfiltration callback. - **Trigger:** npm installation triggers preinstall. - **Impact:** It exposes the installing user's account name and machine hostname to a third party. - **Evidence paths:** package.json - **Review source:** ai\_review - **Reviewed:** 2026-09-14T03:37:16.977Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Shell command collects identity values and sends them by HTTP. - **Attack narrative:** The package defines a preinstall command that runs curl before installation completes. It expands whoami and hostname into the request path and transmits both to an external OAST service. The callback occurs without an explicit user command and is unrelated to installing package functionality. - **Rationale:** Direct inspection confirms an automatic preinstall hook that fingerprints the host and exfiltrates the values over HTTP. This is concrete malicious install-hook abuse. - **Files touched:** package.json - **Network endpoints:** ebtld4p8aq3rl950g6jgn217aygp4fs4.oastify.com ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The preinstall hook sends the current username and hostname to an external OAST host during installation., The network callback is automatic and has no package functionality beyond the stated dependency-confusion proof of concept. ## Affected versions and remediation This report applies to app-rrhh@999.0.0. - Avoid installing app-rrhh@999.0.0. 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.
