It downloads or DNS-reconstructs a payload, writes it under a temp directory, and executes it detached. - **Trigger:** Any Node process that requires the package entrypoint. - **Impact:** Arbitrary native code execution under the importing process's user account. - **Evidence paths:** package.json, index.js, \_bootstrap.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T15:27:42.623Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** import-time remote payload download, drop, and detached execution - **Attack narrative:** The declared entrypoint catches and suppresses errors while importing \_bootstrap.js. That module fingerprints the platform, downloads a platform-specific executable from rotating obfuscated workers.dev hosts or reconstructs one from DNS TXT records, saves it in a temporary directory, makes it executable on Unix, and launches it detached through /bin/sh or cmd.exe. This is unconsented import-time arbitrary code execution. - **Rationale:** This is a concrete staged payload chain reachable on ordinary import, not a configured telemetry feature. No lifecycle hook is needed because the malicious action runs from the main entrypoint. - **Files touched:** index.js, \_bootstrap.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, C:\\Windows\\Temp\\analytics\_state, C:\\Windows\\Temp\\dotnet\_diag\_\.exe - **Network endpoints:** https://oob-worker.cf102-baf.workers.dev/pkg/package, https://oob-worker.cf99-9b3.workers.dev/pkg/package, https://oob-worker.cf101-adf.workers.dev/pkg/package, https://oob-worker.cf100-416.workers.dev/pkg/package, 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 \_bootstrap.js on every package import., \_bootstrap.js downloads platform binaries from four obfuscated workers.dev hosts., \_bootstrap.js falls back to DNS TXT payload retrieval from \*.dl.wel1.ru., Downloaded bytes are written to a temp file, chmodded, and spawned detached via shell/cmd., The bootstrap suppresses errors/output and rate-limits runs with a temp stamp. - **Evidence against:** package.json has no lifecycle scripts., lib/telemetry.js is not imported by the declared entrypoint. ## Public findings ### 1.
