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:** 35.2.2 - **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. Source inspection confirms an import-time staged payload downloader and detached executor, with no legitimate integration path exposed by the advertised wrapper. Absence of an npm lifecycle hook does not mitigate execution on normal import. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-08-05T19:16:30.560Z - **Finished:** 2026-08-05T19:16:55.398Z - **Download time:** 255 ms - **Static scan time:** 29 ms - **AI review time:** 24553 ms - **Total time:** 24838 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 retrieves an executable payload and starts it in the background. The behavior is unrelated to the advertised API-adapter functionality. - **Trigger:** Any runtime require/import of index.js. - **Impact:** Arbitrary remote code executes with the importing process's privileges. - **Evidence paths:** package.json, index.js, \_support.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T19:16:55.398Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote binary download, temporary-file drop, and detached execution. - **Attack narrative:** The public entrypoint suppresses errors while importing \_support.js. That module runs immediately, fetches a platform-specific payload from rotated Workers hosts or reconstructs it from DNS TXT records, drops it in a temporary directory, makes it executable on Unix, and launches it detached through a shell or cmd.exe. This is unconsented remote code execution during ordinary package use. - **Rationale:** Source inspection confirms an import-time staged payload downloader and detached executor, with no legitimate integration path exposed by the advertised wrapper. Absence of an npm lifecycle hook does not mitigate execution on normal import. - **Files touched:** index.js, \_support.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, %TEMP%\\analytics\_state, %TEMP%\\dotnet\_diag\_\.exe - **Network endpoints:** oob-worker.cf103-070.workers.dev, oob-worker.cf100-416.workers.dev, oob-worker.cf102-baf.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 \_support.js on every package import., \_support.js downloads platform binaries over HTTPS or DNS TXT., Downloaded bytes are written to temp, chmodded, and launched detached., Endpoints are obfuscated and unrelated to the advertised REST wrapper. - **Evidence against:** package.json has no lifecycle scripts., No credential harvesting is present in the inspected entrypoint chain. ## Affected versions and remediation This report applies to claims-payout-offer-api-adapters@35.2.2. - Avoid installing claims-payout-offer-api-adapters@35.2.2. 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.
