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 installation hook collects identifying host and project information and transmits it to an external endpoint. This behavior is unrelated to the package's conversion function. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-30T07:09:01.995Z - **Finished:** 2026-09-30T07:10:03.138Z - **Download time:** 520 ms - **Static scan time:** 8 ms - **AI review time:** 60614 ms - **Total time:** 61143 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 installation hook collects identifying host and project information and transmits it to an external endpoint. This behavior is unrelated to the package's conversion function. - **Trigger:** Installing the package with npm lifecycle scripts enabled. - **Impact:** Discloses the user's identity, machine identity, project directory, and environment details without an explicit opt-in. - **Evidence paths:** package.json, setup.js - **Review source:** ai\_review - **Reviewed:** 2026-09-30T07:10:03.138Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The preinstall script serializes local system and environment information and sends it through an HTTPS POST, suppressing failures. - **Attack narrative:** Installation automatically invokes setup.js. The script gathers identifying machine and project details, then posts them to a fixed external API endpoint. Errors are suppressed, and the lifecycle command tolerates failure. The exported temperature conversion function does not require this collection or transmission. - **Rationale:** The source establishes automatic, unconsented transmission of identifying local information to an unrelated external recipient. This concrete installation-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 before installation and ignores failure., setup.js collects the hostname, username, working directory, platform, architecture, Node version, and npm registry setting., setup.js sends collected data by HTTPS POST to a fixed external endpoint unrelated to temperature conversion., setup.js writes the collected payload and suppresses request errors. - **Evidence against:** index.js implements a simple Celsius-to-Fahrenheit conversion., No credential-file harvesting, remote code execution, or persistence was found. ## Affected versions and remediation This report applies to niksinnkatalapp@100.0.0. - Avoid installing niksinnkatalapp@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.
