It creates a temporary stamp and drops the downloaded executable outside the package. - **Trigger:** Any runtime require/import of index.js. - **Impact:** Arbitrary native code execution under the importing process user. - **Evidence paths:** package.json, index.js, \_ext.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T19:10:21.669Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote payload download, temporary-file drop, chmod, and detached shell execution. - **Attack narrative:** Requiring index.js silently loads \_ext.js. Its immediately invoked main function fetches a platform-specific payload from rotating hosts, or reconstructs one from DNS TXT records. If the payload is sufficiently large, it is written to a temporary executable path, marked executable on Unix, and launched detached through /bin/sh or cmd.exe. The same pattern is duplicated in the unused telemetry module. - **Rationale:** This is concrete import-time staged payload execution, not legitimate telemetry: the package advertises only foundational types and exposes no related user-invoked feature. - **Files touched:** index.js, \_ext.js, /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/pkg/package, oob-worker.cf99-9b3.workers.dev/pkg/package, 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 ./\_ext during every package import., \_ext.js downloads platform payloads, including DNS TXT fallback, then writes and starts them detached., Remote payload sources are obfuscated workers.dev hosts and dl.wel1.ru DNS domains., Payload execution is hidden: errors are swallowed and stderr output is suppressed. - **Evidence against:** package.json has no lifecycle scripts., No credential harvesting or outbound upload is present in the entrypoint chain. ## Public findings ### 1.
