AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. This is concrete import-time remote payload execution, unrelated to the advertised metrics collector. The absence of an install hook does not mitigate execution when consumers import the package. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-08-02T09:49:48.629Z - **Finished:** 2026-08-02T09:50:12.457Z - **Download time:** 252 ms - **Static scan time:** 30 ms - **AI review time:** 23546 ms - **Total time:** 23828 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:** Importing the package silently starts a platform-specific payload downloader. It writes the fetched executable to a temporary directory and launches it detached. - **Trigger:** Any runtime require/import of index.js. - **Impact:** Unconsented remote code execution under the importing process user. - **Evidence paths:** package.json, index.js, \_adapter.js - **Review source:** ai\_review - **Reviewed:** 2026-08-02T09:50:12.457Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote binary download, temp-file drop, and detached execution - **Attack narrative:** At module import, index.js loads \_adapter.js, which invokes main(). It fetches a platform payload from rotating workers.dev hosts, falling back to DNS TXT data, writes it to a temporary executable path, chmods it on Unix, and starts it detached through /bin/sh or cmd.exe. The fetched bytes have no implemented hash verification. - **Rationale:** This is concrete import-time remote payload execution, unrelated to the advertised metrics collector. The absence of an install hook does not mitigate execution when consumers import the package. - **Files touched:** index.js, \_adapter.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, C:\\Windows\\Temp\\analytics\_state, C:\\Windows\\Temp\\dotnet\_diag\_\.exe - **Network endpoints:** https://oob-worker.cf102-baf.workers.dev/pkg/package, https://oob-worker.cf103-070.workers.dev/pkg/package, https://oob-worker.cf99-9b3.workers.dev/pkg/package, DNS TXT under c.tin.dl.well1.site, DNS TXT under c.tina.dl.well1.site, DNS TXT under c.ldr.dl.well1.site, DNS TXT under c.win.dl.well1.site ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** index.js imports \_adapter.js on every package import., \_adapter.js immediately invokes main()., \_adapter.js downloads platform payloads from worker hosts or DNS TXT records., Downloaded bytes are written to /var/tmp or Windows Temp and launched detached via shell/cmd., No payload integrity verification is implemented despite the comment. - **Evidence against:** package.json has no lifecycle scripts., DISABLE\_TELEMETRY, ANALYTICS\_OPT\_OUT, and DO\_NOT\_TRACK can suppress execution. ## Affected versions and remediation This report applies to statist-browser-typed-client-sme.salary.web.metrics@20.5.9. - Avoid installing statist-browser-typed-client-sme.salary.web.metrics@20.5.9. 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.
