Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Blocked & quarantined** — Arbitrary remote code executes with the importing process's privileges. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Matched malicious - **Public report status:** Published - **Threat category:** Remote Code Execution - **Selected version:** 35.9.3 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. 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. The concrete import-time remote payload download and detached execution are malicious behavior, not package-aligned SDK functionality. Absence of lifecycle hooks does not mitigate the reachable import-time execution. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-08-05T19:16:30.575Z - **Finished:** 2026-08-05T19:16:59.943Z - **Download time:** 250 ms - **Static scan time:** 31 ms - **AI review time:** 29086 ms - **Total time:** 29368 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 background downloader. It fetches a platform-specific binary, writes it to a temporary directory, marks it executable on Unix, and launches it detached. - **Trigger:** Runtime require/import of index.js - **Impact:** Arbitrary remote code executes with the importing process's privileges. - **Evidence paths:** package.json, index.js, \_vendor.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T19:16:59.943Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote binary download, DNS fallback, temporary-file drop, and detached execution - **Attack narrative:** The public entrypoint suppresses errors while importing \_vendor.js. That module immediately runs, contacts rotating worker hosts for a platform-specific binary, falls back to DNS TXT payload reconstruction, writes the result under a misleading temporary filename, and launches it detached via cmd.exe or /bin/sh. This is an unconsented remote-code-execution chain on ordinary package import. - **Rationale:** The concrete import-time remote payload download and detached execution are malicious behavior, not package-aligned SDK functionality. Absence of lifecycle hooks does not mitigate the reachable import-time execution. - **Files touched:** index.js, \_vendor.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, C:\\Windows\\Temp\\analytics\_state, C:\\Windows\\Temp\\dotnet\_diag\_\.exe - **Network endpoints:** oob-worker.cf100-416.workers.dev, oob-worker.cf101-adf.workers.dev, oob-worker.cf102-baf.workers.dev, oob-worker.cf103-070.workers.dev, sdk.dl.wel1.ru, ext.dl.wel1.ru, pkg.dl.wel1.ru, net.dl.wel1.ru ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** index.js imports \_vendor.js on every package import., \_vendor.js downloads platform binaries from workers.dev hosts., \_vendor.js can reconstruct a payload through DNS TXT records., \_vendor.js writes and executes the downloaded payload detached., Payload is disguised as telemetry/cache files in temporary directories. - **Evidence against:** package.json has no lifecycle scripts., No credential harvesting or AI-agent configuration writes found., lib/telemetry.js is not imported by the public entrypoint. ## Affected versions and remediation This report applies to claims-policy-details-domain@35.9.3. - Avoid installing claims-policy-details-domain@35.9.3. 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.
