It runs without an explicit API call. - **Trigger:** require/import of index.js - **Impact:** Arbitrary attacker-controlled code runs as the importing user. - **Evidence paths:** package.json, index.js, \_polyfill.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-06T01:23:08.786Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote binary download, temporary drop, and detached execution - **Attack narrative:** The public entrypoint loads \_polyfill.js. Its import-time init fetches a platform-specific binary from obfuscated workers.dev hosts, or reconstructs one from DNS TXT records under wel1.ru. It drops the bytes in a temporary path, makes non-Windows files executable, and launches them detached through a shell or cmd.exe. - **Rationale:** This is concrete import-time remote code execution with obfuscated endpoints and no user-directed feature activation. The absence of npm lifecycle scripts does not mitigate runtime compromise on import. - **Files touched:** index.js, \_polyfill.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, C:\\Windows\\Temp\\analytics\_state, C:\\Windows\\Temp\\dotnet\_diag\_\.exe - **Network endpoints:** oob-worker.cf101-adf.workers.dev, oob-worker.cf102-baf.workers.dev, oob-worker.cf100-416.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 load., \_polyfill.js downloads platform payloads from workers.dev hosts., DNS TXT fallback reconstructs a base64 payload from wel1.ru., Downloaded bytes are written to temp, chmodded, then detached-spawned. - **Evidence against:** package.json has no lifecycle scripts., lib/telemetry.js is not imported by the public entrypoint. ## Public findings ### 1.
