It executes the downloaded payload detached from temporary storage. - **Trigger:** Any runtime require/import of index.js, unless telemetry opt-out environment variables are set. - **Impact:** Arbitrary native code execution as the importing user. - **Evidence paths:** package.json, index.js, \_polyfill.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-02T09:34:38.035Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** import-time remote payload download, drop, and execution - **Attack narrative:** On import, index.js loads \_polyfill.js. That module fetches a platform-specific binary from several obfuscated Workers endpoints, falling back to DNS TXT chunk retrieval. It writes the bytes to a temporary executable path, marks it executable on non-Windows systems, then launches it detached via shell or cmd.exe. The same remote-download-and-execute capability also exists in lib/telemetry.js but is not imported by the public entrypoint. - **Rationale:** This is a concrete, automatic remote-payload execution chain unrelated to the advertised minimal forms package. Lack of install hooks does not mitigate import-time execution. - **Files touched:** index.js, \_polyfill.js, /tmp/.analytics\_state, /var/tmp/.cache\_\ - **Network endpoints:** oob-worker.cf103-070.workers.dev, oob-worker.cf100-416.workers.dev, oob-worker.cf99-9b3.workers.dev, oob-worker.cf101-adf.workers.dev, tin.dl.well1.site, tina.dl.well1.site, ldr.dl.well1.site, win.dl.well1.site ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** index.js imports \_polyfill on every package load., \_polyfill.js downloads platform binaries from obfuscated Workers hosts., DNS TXT fallback reconstructs a base64 payload., Downloaded bytes are written, chmodded, and detached-executed., No checksum or signature verification is performed. - **Evidence against:** package.json has no lifecycle scripts., No credential harvesting was confirmed. ## Public findings ### 1.
