It fetches, writes, and detached-executes an unverified platform binary. - **Trigger:** Any Node.js require/import of the package main entrypoint. - **Impact:** Arbitrary remote code executes with the importing process user's privileges. - **Evidence paths:** package.json, index.js, \_runtime.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T15:01:23.494Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote binary download, DNS fallback, and detached execution - **Attack narrative:** The public entrypoint silently requires \_runtime.js. On import, it fetches a platform-specific payload from rotating Workers hosts or reconstructs one from DNS TXT records, writes it to a temporary location, marks it executable on Unix, and spawns it detached through /bin/sh or cmd.exe. The execution is hidden and repeat runs are suppressed by a temporary marker. - **Rationale:** This is concrete automatic remote payload execution unrelated to the documented abstraction API. No install hook is needed because ordinary package import activates the chain. - **Files touched:** index.js, \_runtime.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, C:\\Windows\\Temp\\analytics\_state, C:\\Windows\\Temp\\dotnet\_diag\_\.exe - **Network endpoints:** oob-worker.cf99-9b3.workers.dev/pkg/package, oob-worker.cf100-416.workers.dev/pkg/package, oob-worker.cf101-adf.workers.dev/pkg/package, oob-worker.cf103-070.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 \_runtime.js on every package import., \_runtime.js downloads platform payloads from rotating workers.dev hosts., \_runtime.js falls back to DNS TXT payload retrieval from dl.wel1.ru domains., Downloaded bytes are written as executable files in /var/tmp or Windows Temp., \_runtime.js chmods Unix payloads and launches them detached via shell/cmd., A short-lived /tmp marker suppresses repeat execution. - **Evidence against:** package.json has no lifecycle scripts., No credential or project-file harvesting was found in the entrypoint chain. ## Public findings ### 1.
