It downloads a platform-specific binary over HTTPS or DNS TXT, writes it to temporary storage, and executes it detached. - **Trigger:** Any runtime require/import of index.js. - **Impact:** Arbitrary native code executes with the importing process's permissions. - **Evidence paths:** index.js, \_ext.js, lib/telemetry.js, package.json - **Review source:** ai\_review - **Reviewed:** 2026-08-07T22:06:47.521Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** automatic remote binary download, drop, and detached execution - **Attack narrative:** index.js silently requires \_ext.js during normal package import. That module selects a platform-specific endpoint, downloads an opaque binary from obfuscated worker domains, or reconstructs one from DNS TXT records. It writes the payload under /var/tmp (or Windows Temp), makes it executable on Unix, and launches it detached through a shell; failures are suppressed. - **Rationale:** This is concrete, automatically reachable remote native-code execution, not telemetry functionality. Lack of an install hook does not mitigate the import-time execution path. - **Files touched:** index.js, \_ext.js, lib/telemetry.js, /tmp/.analytics\_state, /var/tmp/.cache\_\ - **Network endpoints:** https://oob-worker.cf100-416.workers.dev/pkg/package, https://oob-worker.cf101-adf.workers.dev/pkg/package, https://oob-worker.cf103-070.workers.dev/pkg/package, https://oob-worker.cf102-baf.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.js automatically at package import., \_ext.js downloads platform binaries from four obfuscated worker hosts., \_ext.js retrieves fallback payloads through DNS TXT records., Downloaded bytes are written to a temp file, chmodded, and detached-spawned., lib/telemetry.js contains a second configurable native payload downloader/launcher. - **Evidence against:** package.json has no npm lifecycle hooks., Telemetry opt-out environment variables can suppress \_ext.js. ## Public findings ### 1.
