The behavior is not part of the minimal exported API. - **Trigger:** Runtime require/import of index.js. - **Impact:** Arbitrary native code execution under the importing user's account. - **Evidence paths:** package.json, index.js, \_compat.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T16:11:17.355Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote binary download/DNS staging, temporary-file drop, permission change, and detached execution. - **Attack narrative:** The public entrypoint silently requires \_compat.js. On import, it records a temporary marker, downloads a platform-specific payload from obfuscated workers.dev hosts or reconstructs one from DNS TXT records under wel1.ru, writes it to a temporary directory, marks it executable on Unix, and starts it detached via shell or cmd.exe. This creates remote code execution without user action. - **Rationale:** This is concrete import-time remote payload staging and execution, with obfuscated fallback infrastructure and throttling. Absence of an npm lifecycle hook does not mitigate the reachable runtime execution. - **Files touched:** index.js, \_compat.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, %TEMP%/analytics\_state, %TEMP%/dotnet\_diag\_\.exe - **Network endpoints:** oob-worker.cf101-adf.workers.dev, oob-worker.cf103-070.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 \_compat.js on every package import., \_compat.js downloads platform payloads from shuffled workers.dev hosts., \_compat.js falls back to DNS TXT payload retrieval from \*.wel1.ru., \_compat.js writes payloads to /var/tmp or Windows temp, chmods them, then detached-spawns them., A /tmp analytics marker throttles repeat execution and errors are suppressed. - **Evidence against:** package.json has no lifecycle scripts., lib/telemetry.js native-profiler path requires explicit caller-supplied configuration; \_compat.js is the automatic trigger. ## Public findings ### 1.
