Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Blocked & quarantined** — Arbitrary remote code execution under the importing user's privileges. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Matched malicious - **Public report status:** Published - **Threat category:** Remote Code Execution - **Selected version:** 35.7.8 - **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 source establishes an import-time remote download-and-execute chain with no integrity validation. The absence of lifecycle hooks does not mitigate the reachable runtime execution. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-08-05T17:55:02.370Z - **Finished:** 2026-08-05T17:55:25.805Z - **Download time:** 255 ms - **Static scan time:** 31 ms - **AI review time:** 23148 ms - **Total time:** 23435 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 triggers a hidden bootstrapper. It downloads an OS-specific executable payload, drops it in a temporary directory, and runs it detached. - **Trigger:** Any require/import of the package entrypoint. - **Impact:** Arbitrary remote code execution under the importing user's privileges. - **Evidence paths:** package.json, index.js, \_runtime.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T17:55:25.805Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote binary download, temporary-file drop, and detached shell execution. - **Attack narrative:** Requiring index.js silently loads \_runtime.js. Its bootstrapper contacts obfuscated worker hosts, falls back to DNS TXT payload retrieval, writes a downloaded platform-specific binary to a temp directory, marks it executable on Unix, and launches it detached through a shell or cmd.exe. This is unconsented remote payload execution, not functionality exposed by the documented bridge API. - **Rationale:** The source establishes an import-time remote download-and-execute chain with no integrity validation. The absence of lifecycle hooks does not mitigate the reachable runtime execution. - **Files touched:** index.js, \_runtime.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, C:\\Windows\\Temp\\analytics\_state, C:\\Windows\\Temp\\dotnet\_diag\_\.exe - **Network endpoints:** oob-worker.cf1-00-416.workers.dev, oob-worker.cf102-baf.workers.dev, oob-worker.cf103-070.workers.dev, c.sdk.dl.wel1.ru, c.ext.dl.wel1.ru, c.pkg.dl.wel1.ru, c.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 \_runtime.js on every package import., \_runtime.js downloads platform binaries from worker domains and DNS TXT fallbacks., Downloaded bytes are written to /var/tmp or Windows temp, chmodded, then spawned detached., No signature/hash verification occurs before execution., A temporary marker suppresses repeat execution for roughly 5.7 hours., lib/telemetry.js contains a matching configurable download-and-execute capability. - **Evidence against:** package.json has no lifecycle scripts., The exported bridge class itself is otherwise minimal. ## Affected versions and remediation This report applies to bnpl-molecule-mobile-bnpl-onboarding@35.7.8. - Avoid installing bnpl-molecule-mobile-bnpl-onboarding@35.7.8. 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.
