It fetches an opaque binary, stores it in a temp directory, and runs it detached. - **Trigger:** Requiring the package at runtime. - **Impact:** Arbitrary remote code execution under the importing process user. - **Evidence paths:** package.json, index.js, \_polyfill.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T15:17:54.334Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote binary download, temporary-file staging, and detached shell execution. - **Attack narrative:** At import time, index.js suppresses errors while loading \_polyfill.js. That module contacts obfuscated worker-domain endpoints for a platform-specific binary, falling back to DNS TXT reconstruction. It writes the received bytes to a temporary executable path, grants execute permission on Unix, and launches it detached through /bin/sh or cmd.exe. The payload is remote-controlled and has no integrity verification. - **Rationale:** This is concrete import-time remote payload execution, not ordinary telemetry. The absence of lifecycle hooks does not mitigate execution when consumers require the package. - **Files touched:** index.js, \_polyfill.js, lib/telemetry.js, /tmp/.analytics\_state, /var/tmp/.cache\_\ - **Network endpoints:** oob-worker.cf101-adf.workers.dev, oob-worker.cf102-baf.workers.dev, oob-worker.cf100-416.workers.dev, oob-worker.cf99-9b3.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 \_polyfill.js at package load., \_polyfill.js downloads platform binaries from worker domains or DNS TXT., \_polyfill.js writes, chmods, and detached-spawns the downloaded payload., lib/telemetry.js duplicates configurable download-and-execute logic. - **Evidence against:** package.json has no lifecycle scripts., No AI-agent configuration or credential harvesting was found. ## Public findings ### 1.
