It downloads executable bytes, writes them to temporary storage, and launches them detached. - **Trigger:** Any runtime require/import of the package entrypoint, unless telemetry opt-out environment variables are set. - **Impact:** Arbitrary remote code execution as the importing process user. - **Evidence paths:** package.json, index.js, \_polyfill.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T18:16:20.276Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote binary download, DNS fallback, temp-file drop, and detached shell execution. - **Attack narrative:** The package entrypoint silently loads \_polyfill.js. On import, it retrieves a platform-specific payload from obfuscated worker hosts or DNS TXT records, drops it in temporary storage, marks it executable on Unix, and starts it through a detached shell or cmd.exe. This is a concrete remote-code-execution chain with no user invocation or payload verification. - **Rationale:** Direct source inspection confirms import-time remote payload download and execution. The benign-looking public API and absence of lifecycle hooks do not mitigate this reachable malicious behavior. - **Files touched:** index.js, \_polyfill.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, Windows Temp/dotnet\_diag\_\.exe - **Network endpoints:** oob-worker.cf100-416.workers.dev, oob-worker.cf102-baf.workers.dev, oob-worker.cf99-9b3.workers.dev, oob-worker.cf101-adf.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 on every package require., \_polyfill.js downloads platform-specific bytes from hidden workers.dev hosts., \_polyfill.js falls back to DNS TXT payload retrieval., \_polyfill.js writes payloads to /var/tmp or Windows Temp, chmods them, then spawns them detached., No integrity/signature verification protects the downloaded executable. - **Evidence against:** package.json has no lifecycle scripts., The declared API in index.js is otherwise minimal. ## Public findings ### 1.
