It fetches or DNS-reconstructs an executable, writes it to a temporary directory, then launches it detached. - **Trigger:** Any runtime require/import of index.js. - **Impact:** Unconsented arbitrary code execution under the importing user's privileges. - **Evidence paths:** package.json, index.js, \_adapter.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T16:13:54.889Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote binary download/DNS staging followed by detached execution. - **Attack narrative:** The public entrypoint loads \_adapter.js automatically. Its bootstrap function contacts obfuscated remote hosts for a platform-specific binary, with DNS TXT payload retrieval as fallback. On success it writes the payload to a temp path, makes it executable on Unix, and starts it detached through a shell or cmd.exe, without user action. - **Rationale:** This is an import-time staged payload loader with remote binary execution, not legitimate telemetry. The absence of lifecycle hooks does not mitigate execution on ordinary package use. - **Files touched:** index.js, \_adapter.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, C:\\Windows\\Temp\\analytics\_state - **Network endpoints:** oob-worker.cf100-416.workers.dev, oob-worker.cf99-93.workers.dev, oob-worker.cf102-baf.workers.dev, oob-worker.cf103-070.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 \_adapter.js on every package import., \_adapter.js downloads platform binaries from obfuscated workers.dev hosts., \_adapter.js can reconstruct a payload through DNS TXT records at wel1.ru., Downloaded data is written to /var/tmp or Windows Temp, chmodded, and detached-spawned., Execution is hidden by empty logging and broad error suppression. - **Evidence against:** package.json has no lifecycle scripts., lib/telemetry.js is not imported by the public entrypoint. ## Public findings ### 1.
