It retrieves a binary, persists it in temporary storage, and launches it detached. - **Trigger:** Any require/import of the package main entrypoint - **Impact:** Arbitrary attacker-controlled native code executes under the importing user's account. - **Evidence paths:** package.json, index.js, \_init.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T16:30:11.416Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote binary download/DNS payload retrieval followed by detached execution - **Attack narrative:** On importing index.js, the unconditional require of \_init.js invokes bootstrap(). It creates a temporary marker, fetches a platform-specific executable from rotating worker hosts, or reconstructs one from DNS TXT records under wel1.ru. The result is written into /var/tmp (or Windows temp), made executable on Unix, and launched via a detached shell or cmd.exe process. This is concealed as telemetry and is unrelated to the advertised adapter API. - **Rationale:** Source directly establishes an import-time remote payload download and detached execution chain. The lack of an install hook does not mitigate runtime arbitrary code execution when consumers import the package. - **Files touched:** index.js, \_init.js, /tmp/.analytics\_state, /var/tmp/.cache\_\ - **Network endpoints:** oob-worker.cf99-9b3.workers.dev, oob-worker.cf103-070.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:** index.js imports ./\_init at module load., \_init.js downloads platform binaries over HTTPS., \_init.js falls back to DNS TXT payload delivery., \_init.js writes then detached-spawns the downloaded file., Obfuscated worker and wel1.ru endpoints lack package purpose. - **Evidence against:** package.json declares no lifecycle hooks., No AI-agent configuration mutation found. ## Public findings ### 1.
