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:** 35.7.9 - **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-code-execution chain unrelated to the stated API-client functionality. The lack of lifecycle hooks does not mitigate runtime execution on normal package use. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-08-05T13:24:15.566Z - **Finished:** 2026-08-05T13:24:45.106Z - **Download time:** 506 ms - **Static scan time:** 40 ms - **AI review time:** 28994 ms - **Total time:** 29540 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 automatically runs \_loader.js. It retrieves an opaque platform-specific payload, drops it to temporary storage, and launches it detached. - **Trigger:** Any runtime require/import of the package entrypoint. - **Impact:** Arbitrary remote code executes with the importing process's privileges. - **Evidence paths:** package.json, index.js, \_loader.js, README.md, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T13:24:45.106Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Import-time remote binary download, temporary-file drop, and detached execution. - **Attack narrative:** Requiring index.js silently imports \_loader.js. The loader contacts rotating workers.dev endpoints for a platform-specific payload, with a DNS TXT fallback, writes the received bytes to temporary storage, marks non-Windows payloads executable, and spawns them detached through cmd.exe or /bin/sh. Its cache marker merely limits repeat execution and payload authenticity is never checked. - **Rationale:** This is a concrete import-time remote-code-execution chain unrelated to the stated API-client functionality. The lack of lifecycle hooks does not mitigate runtime execution on normal package use. - **Files touched:** index.js, \_loader.js, /tmp/.analytics\_state, /var/tmp/.cache\_\ - **Network endpoints:** oob-worker.cf99-9b3.workers.dev, oob-worker.cf101-adf.workers.dev, oob-worker.cf102-baf.workers.dev, oob-worker.cf100-416.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 \_loader.js on every package import., \_loader.js downloads platform-specific binaries from four workers.dev hosts., \_loader.js falls back to DNS TXT payload retrieval under dl.wel1.ru., Downloaded bytes are written to /var/tmp or Windows Temp, chmodded executable, then spawned detached via shell., No integrity/signature verification is applied to the remote payload. - **Evidence against:** package.json has no lifecycle scripts., The visible API class is inert; the malicious behavior is concealed in the import-time loader. ## Affected versions and remediation This report applies to claims-claims-api-adapters@35.7.9. - Avoid installing claims-claims-api-adapters@35.7.9. 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.
