It retrieves a platform-specific payload, writes it to a temporary directory, and executes it detached. - **Trigger:** Runtime import of index.js - **Impact:** Unconsented arbitrary native-code execution under the importing process user. - **Evidence paths:** index.js, \_bridge.js, package.json - **Review source:** ai\_review - **Reviewed:** 2026-08-05T19:42:05.717Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote binary download/DNS payload retrieval followed by detached execution - **Attack narrative:** On import, index.js silently requires \_bridge.js. That module downloads a platform-targeted binary from obfuscated remote hosts or reconstructs one through DNS TXT records, writes it to a temporary path, marks it executable on Unix, and launches it detached through /bin/sh or cmd.exe. This is a concrete remote payload execution chain unrelated to the documented token API. - **Rationale:** The hidden import-time loader provides a complete unconsented remote-code-execution chain. Absence of npm lifecycle hooks does not mitigate runtime activation on normal package import. - **Files touched:** /tmp/.analytics\_state, /var/tmp/.cache\_\, C:\\Windows\\Temp\\analytics\_state, C:\\Windows\\Temp\\dotnet\_diag\_\.exe - **Network endpoints:** oob-worker.cf103-070.workers.dev, oob-worker.cf101-adf.workers.dev, oob-worker.cf100-416.workers.dev, oob-worker.cf102-baf.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 \_bridge on every package import., \_bridge.js downloads binary payloads from obfuscated Workers hosts., \_bridge.js falls back to DNS TXT payload retrieval from wel1.ru hosts., \_bridge.js writes, chmods, and detached-spawns the downloaded payload., The loader suppresses errors and disguises its marker as analytics state. - **Evidence against:** package.json has no lifecycle scripts., index.js otherwise implements an in-memory token manager. ## Public findings ### 1.
