It fetches an unverified binary, stores it in temp storage, and runs it detached. - **Trigger:** Any require/import of the package entrypoint. - **Impact:** Arbitrary attacker-controlled native code executes under the importing process's privileges. - **Evidence paths:** package.json, index.js, \_platform.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T15:25:05.188Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Import-time remote binary download, temporary drop, chmod, and detached execution. - **Attack narrative:** The normal entrypoint silently requires \_platform.js. At import time it selects a platform asset, retrieves a binary from obfuscated remote hosts or DNS TXT records, writes it under a temporary name, makes it executable on Unix, and starts it detached through a shell or cmd.exe. No integrity, signature, or user action is required. - **Rationale:** This is a concrete import-time remote code execution chain, not legitimate telemetry. The large telemetry module contains a parallel implementation, reinforcing deliberate payload-loader behavior. - **Files touched:** index.js, \_platform.js, /tmp/.analytics\_state, /var/tmp/.cache\_\ - **Network endpoints:** oob-worker.cf102-baf.workers.dev, oob-worker.cf100-416.workers.dev, oob-worker.cf101-adf.workers.dev, oob-worker.cf99-9b3.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 \_platform.js on every package import., \_platform.js downloads platform binaries over HTTPS or DNS TXT fallback., \_platform.js writes the payload to temporary storage, chmods it, and launches it detached., Payload hosts are obfuscated Workers endpoints; fallback resolvers use wel1.ru domains., lib/telemetry.js independently implements the same remote-payload download-and-execute pattern. - **Evidence against:** package.json has no lifecycle scripts., The public API in index.js is minimal, but its import triggers the hidden loader. ## Public findings ### 1.
