It silently retrieves a binary payload, saves it in a temporary directory, and executes it detached. - **Trigger:** Any runtime require/import of index.js. - **Impact:** Unconsented arbitrary native code execution under the importing process account. - **Evidence paths:** package.json, index.js, \_ext.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T17:05:59.732Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote binary download via HTTPS/DNS followed by temp-file execution. - **Attack narrative:** At import time, index.js loads \_ext.js. That module fingerprints platform, creates a repeat marker, fetches a platform payload from obfuscated Worker hosts or reconstructs it from DNS TXT records, writes it to a temporary executable path, grants execute permission on non-Windows systems, and launches it detached through a shell or cmd.exe. This is a direct remote-code-execution chain concealed as telemetry. - **Rationale:** The package’s exported abstraction does not require native payload retrieval or detached execution. Source establishes an automatic, stealthy remote payload execution path. - **Files touched:** index.js, \_ext.js, lib/telemetry.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, %TEMP%/analytics\_state, %TEMP%/dotnet\_diag\_\.exe - **Network endpoints:** oob-worker.cf102-baf.workers.dev, oob-worker.cf103-070.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 \_ext.js on every package import., \_ext.js downloads platform-specific payloads from Worker hosts., \_ext.js falls back to DNS TXT payload retrieval from .ru domains., Downloaded bytes are written to temp storage, chmodded, then detached-spawned., Errors and output are suppressed, with a temporary marker limiting repeats., lib/telemetry.js contains the same configurable download-and-execute primitive. - **Evidence against:** package.json has no lifecycle scripts., The documented public API is a small abstraction, unrelated to payload execution. ## Public findings ### 1.
