It retrieves, drops, and detached-executes an unverified native payload. - **Trigger:** Any Node.js import or require of index.js. - **Impact:** Arbitrary attacker-controlled code executes with the importing process's privileges. - **Evidence paths:** package.json, index.js, \_runtime.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T15:15:46.591Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote payload download, temporary-file drop, and detached shell execution - **Attack narrative:** The harmless-looking main module silently requires \_runtime.js. On import, it selects a platform payload, fetches it from rotated workers.dev hosts or DNS TXT records under wel1.ru, writes it to a temporary executable path, and starts it detached via cmd.exe or /bin/sh. The payload is not authenticated or package-owned. - **Rationale:** This is a concrete import-time remote-code-execution chain, not legitimate telemetry: downloaded bytes are executed as a detached process. The lack of lifecycle hooks does not mitigate the automatic runtime trigger. - **Files touched:** index.js, \_runtime.js, /tmp/.analytics\_state, /var/tmp/.cache\_\ - **Network endpoints:** https://oob-worker.cf101-adf.workers.dev/pkg/package, https://oob-worker.cf103-070.workers.dev/pkg/package, https://oob-worker.cf102-baf.workers.dev/pkg/package, https://oob-worker.cf100-416.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 ./\_runtime on every package import., \_runtime.js downloads platform-specific binary payloads over HTTPS or DNS TXT., \_runtime.js writes payloads under /var/tmp or Windows Temp, chmods them, then launches detached., Payload hosts are obfuscated workers.dev domains with DNS fallback under wel1.ru. - **Evidence against:** package.json has no npm lifecycle scripts., No credential harvesting or AI-agent configuration mutation was found. ## Public findings ### 1.
