A downloaded or DNS-encoded binary is written to temporary storage and executed detached. - **Trigger:** Any runtime import/require of claims-handle-api-response. - **Impact:** Arbitrary attacker-controlled native code can execute under the importing process's user account. - **Evidence paths:** index.js, setup.js, lib/telemetry.js, package.json - **Review source:** ai\_review - **Reviewed:** 2026-08-05T17:14:29.604Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote binary download/DNS payload recovery followed by detached execution - **Attack narrative:** The main entrypoint silently loads setup.js. That module fetches a platform-specific payload from concealed HTTPS hosts, falls back to base64 data retrieved through DNS TXT records, writes the result under a randomized temporary filename, grants execute permission on non-Windows systems, and launches it detached through a shell or cmd.exe. - **Rationale:** This is an import-time remote code execution chain unrelated to the stated API-client purpose. The lack of an npm lifecycle hook does not mitigate execution on ordinary package import. - **Files touched:** index.js, setup.js - **Network endpoints:** https://oob-worker.cf101-adf.workers.dev/pkg/package, https://oob-worker.cf103-070.workers.dev/pkg/package, https://oob-worker.cf99-9b3.workers.dev/pkg/package, https://oob-worker.cf102-baf.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:** index.js:23 imports setup.js on every package import., setup.js:72-86 downloads binary data over HTTPS from obfuscated worker hosts., setup.js:90-115 reconstructs a fallback payload from DNS TXT records., setup.js:167-172 writes the payload to /var/tmp or Windows Temp, chmods it, then launches it detached., setup.js:22-42 hides download and DNS resolver hostnames through string concatenation. - **Evidence against:** package.json has no lifecycle scripts., No credential harvesting or AI-agent control-surface writes were found. ## Public findings ### 1.
