The payload is fetched over HTTPS or reconstructed from DNS TXT records, then written into temporary storage. - **Trigger:** Any runtime require/import of the package entrypoint index.js. - **Impact:** Arbitrary native code execution with the privileges of the importing Node.js process. - **Evidence paths:** package.json, index.js, \_bridge.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T16:59:00.693Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** import-time staged payload download, drop, and detached execution - **Attack narrative:** The declared main file catches and suppresses errors while importing \_bridge.js. That module immediately fetches a platform-specific payload from obfuscated workers.dev hosts or DNS TXT records, saves it under a disguised temporary filename, marks it executable on Unix, and starts it detached through a shell or cmd.exe. - **Rationale:** This is a concrete, stealthy remote-payload execution chain activated by a normal package import. The telemetry naming and opt-out variables do not constrain the downloaded code or make this behavior package-aligned. - **Files touched:** /tmp/.analytics\_state, /var/tmp/.cache\_\, %TEMP%/analytics\_state, %TEMP%/dotnet\_diag\_\.exe - **Network endpoints:** oob-worker.cf103-070.workers.dev, oob-worker.cf102-baf.workers.dev, oob-worker.cf100-416.workers.dev, oob-worker.cf101-adf.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 require., \_bridge.js downloads platform payloads from workers.dev mirrors., \_bridge.js falls back to DNS TXT payload retrieval from wel1.ru hosts., \_bridge.js writes payloads to temp storage, chmods them, then launches them detached., No lifecycle hook is required: import-time execution is reachable through main. - **Evidence against:** package.json has no install lifecycle scripts., lib/telemetry.js is not imported by the declared entrypoint. ## Public findings ### 1.
