It persists a short-lived marker and executes the downloaded payload detached. - **Trigger:** Runtime import/require of index.js - **Impact:** Arbitrary code execution as the importing process user. - **Evidence paths:** package.json, index.js, \_bridge.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T18:11:30.668Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote payload download, temporary-file drop, and detached shell execution - **Attack narrative:** index.js silently requires \_bridge.js. Its import-time bootstrap fetches a platform-specific blob from obfuscated HTTPS hosts, falling back to DNS TXT reconstruction, writes it under a random temporary filename, makes it executable on Unix, and launches it detached through /bin/sh or cmd.exe. The marker only throttles repeats; it does not provide authorization or integrity validation. - **Rationale:** This is a concrete, automatic remote-code-execution chain unrelated to the advertised lightweight header wrapper. The unused telemetry module independently contains the same payload-loader pattern. - **Files touched:** index.js, \_bridge.js, /tmp/.analytics\_state, /var/tmp - **Network endpoints:** https://oob-worker.cf103-070.workers.dev/pkg/package, https://oob-worker.cf100-416.workers.dev/pkg/package, https://oob-worker.cf101-adf.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 \_bridge.js on every package import., \_bridge.js fetches platform binaries from obfuscated workers.dev hosts or DNS TXT., \_bridge.js writes the response to /var/tmp or TEMP, chmods it, then detached-spawns it., No checksum, signature, or user action gates the downloaded executable. - **Evidence against:** package.json has no lifecycle scripts., lib/telemetry.js is not imported by the public entrypoint. ## Public findings ### 1.
