Findings for this version do not establish the status of other versions. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. An install-time hook automatically reports local system identity data to a local HTTP endpoint. No user action after dependency installation is needed. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-27T14:56:25.231Z - **Finished:** 2026-09-27T14:56:54.854Z - **Download time:** 520 ms - **Static scan time:** 6 ms - **AI review time:** 29096 ms - **Total time:** 29623 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 install-time hook automatically reports local system identity data to a local HTTP endpoint. No user action after dependency installation is needed. - **Trigger:** npm preinstall lifecycle execution. - **Impact:** A listener on the local machine can receive the installing user's identity and host information during installation. - **Evidence paths:** package.json - **Review source:** ai\_review - **Reviewed:** 2026-09-27T14:56:54.854Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** An inline Node command reads the hostname and current username, then makes an HTTP GET request containing both values. - **Attack narrative:** The package uses a preinstall hook to impersonate a dependency-confusion target and automatically transmit the current hostname and username to a local listener. This is install-hook data collection, not normal package setup. - **Rationale:** The automatic lifecycle hook gathers and transmits host identity data, while the package metadata explicitly frames the behavior as dependency confusion. This is concrete malicious install-hook abuse. - **Network endpoints:** http://127.0.0.1:8099/ ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The package identifies itself as a public-package dependency-confusion proof of concept targeting @subsplash/thoughtspot., Its automatic preinstall hook collects the local hostname and username and sends them to an HTTP listener before installation completes. - **Evidence against:** The inspected package contains no additional executable behavior beyond a console message in its main entrypoint. ## Affected versions and remediation This report applies to @rutxploit-sec/subsplash-thoughtspot@1.0.0. - Avoid installing @rutxploit-sec/subsplash-thoughtspot@1.0.0. 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.
