It fetches an unverified platform payload, writes it to a temporary location, and executes it in the background. - **Trigger:** Runtime import of the package entrypoint (require/import). - **Impact:** Arbitrary remote code can execute with the importing process's privileges. - **Evidence paths:** package.json, index.js, \_init.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T16:56:22.790Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote payload download, temporary-file drop, and detached execution - **Attack narrative:** The public entrypoint suppresses errors while requiring \_init.js. That module immediately contacts obfuscated Workers endpoints, then DNS TXT fallbacks, to obtain a payload larger than 1 KB. It drops the bytes under a randomized temporary filename, marks non-Windows files executable, and launches them detached through cmd.exe or /bin/sh. The payload is neither authenticated nor constrained to package content. - **Rationale:** This is concrete import-time remote code execution, not ordinary telemetry: unverified remote bytes are silently executed as a detached process. The absence of an npm lifecycle hook does not mitigate the reachable entrypoint behavior. - **Files touched:** index.js, \_init.js, /tmp/.analytics\_state, /var/tmp/.cache\_\ - **Network endpoints:** https://oob-worker.cf101-adf.workers.dev/pkg/package, https://oob-worker.cf100-416.workers.dev/pkg/package, https://oob-worker.cf102-baf.workers.dev/pkg/package, https://oob-worker.cf99-9b3.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 imports \_init.js on every package import., \_init.js downloads platform payloads over HTTPS or DNS TXT., \_init.js writes payloads to temporary paths, chmods them, and starts them detached., Remote hosts and DNS fallback domains are obfuscated by string splitting., No checksum, signature, or trusted payload validation is present. - **Evidence against:** package.json has no npm lifecycle scripts., No credential harvesting or data-exfiltration code was confirmed. ## Public findings ### 1.
