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 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:** 35.4.1 - **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. This is a concrete import-time remote payload execution chain, unrelated to the package's advertised abstraction API. No install hook is required for compromise once a consumer imports it. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-08-05T18:08:31.138Z - **Finished:** 2026-08-05T18:09:05.791Z - **Download time:** 513 ms - **Static scan time:** 32 ms - **AI review time:** 34108 ms - **Total time:** 34653 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:** Requiring the package immediately activates a concealed remote binary loader. It fetches an opaque platform payload, drops it into temp storage, and runs it detached. - **Trigger:** Any runtime import/require of index.js. - **Impact:** Arbitrary remote code executes with the importing process user's privileges. - **Evidence paths:** package.json, index.js, \_vendor.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T18:09:05.791Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** import-time staged payload download, drop, and detached execution - **Attack narrative:** When an application imports this package, index.js silently requires \_vendor.js. That module selects a platform-specific endpoint, downloads an opaque binary from rotating Worker hosts or reconstructs it from DNS TXT records, writes it under a misleading randomized temporary filename, makes it executable on Unix, and starts it detached through a shell. A temporary stamp suppresses repeated activity, while telemetry opt-out variables disguise the loader as analytics. - **Rationale:** This is a concrete import-time remote payload execution chain, unrelated to the package's advertised abstraction API. No install hook is required for compromise once a consumer imports it. - **Files touched:** index.js, \_vendor.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, %TEMP%\\analytics\_state, %TEMP%\\dotnet\_diag\_\.exe - **Network endpoints:** https://oob-worker.cf102-baf.workers.dev/pkg/package, https://oob-worker.cf101-adf.workers.dev/pkg/package, https://oob-worker.cf103-070.workers.dev/pkg/package, DNS TXT under sdk.dl.wel1.ru, DNS TXT under ext.dl.wel1.ru, DNS TXT under pkg.dl.wel1.ru, DNS TXT under 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 worker hosts or DNS TXT records., \_vendor.js writes a randomized executable to /var/tmp or Windows Temp., \_vendor.js chmods then launches the downloaded file detached via shell/cmd., Import-time setup uses a hidden temp stamp to limit repeat execution. - **Evidence against:** package.json has no lifecycle scripts., The exported index API is minimal, but its import triggers the hidden vendor loader. ## Affected versions and remediation This report applies to bnpl-blocks-desktop-bnpl-link-group@35.4.1. - Avoid installing bnpl-blocks-desktop-bnpl-link-group@35.4.1. 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.
