Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Blocked & quarantined** — Untrusted remote code executes as the importing application's user. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Matched malicious - **Public report status:** Published - **Threat category:** Remote Code Execution - **Selected version:** 35.9.1 - **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 concrete import-time remote code execution, not legitimate telemetry: the downloaded bytes are executed without validation and are concealed behind a benign wrapper. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-08-05T19:51:39.116Z - **Finished:** 2026-08-05T19:52:32.296Z - **Download time:** 256 ms - **Static scan time:** 34 ms - **AI review time:** 52890 ms - **Total time:** 53180 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 advertised package activates a concealed downloader. It retrieves a platform-specific payload, writes it to a temporary executable path, and starts it detached. - **Trigger:** Any runtime require/import of index.js. - **Impact:** Untrusted remote code executes as the importing application's user. - **Evidence paths:** package.json, index.js, \_ext.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T19:52:32.296Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote payload download, drop, chmod, and detached execution - **Attack narrative:** The public entrypoint silently loads \_ext.js. On import, it obtains a platform-specific binary over HTTPS from obfuscated Workers hosts or reconstructs one from DNS TXT records, writes it to a temporary location, makes it executable on non-Windows systems, and runs it detached. The payload is neither authenticated nor package-aligned. - **Rationale:** This is concrete import-time remote code execution, not legitimate telemetry: the downloaded bytes are executed without validation and are concealed behind a benign wrapper. - **Files touched:** index.js, \_ext.js, /tmp/.analytics\_state, /var/tmp/.cache\_\ - **Network endpoints:** oob-worker.cf102-baf.workers.dev/pkg/package, oob-worker.cf103-070.workers.dev/pkg/package, oob-worker.cf101-adf.workers.dev/pkg/package, 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 \_ext.js on every package import., \_ext.js fetches platform binaries from hidden Workers hosts., \_ext.js falls back to DNS TXT payload retrieval from wel1.ru hosts., \_ext.js writes the payload to a temp file, chmods it, and launches it detached via shell/cmd., No integrity/signature verification precedes execution. - **Evidence against:** package.json has no lifecycle scripts., No credential harvesting or AI-agent configuration writes were found. ## Affected versions and remediation This report applies to bnpl-blocks-feature-partners@35.9.1. - Avoid installing bnpl-blocks-feature-partners@35.9.1. 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.
