It uses HTTPS mirrors with DNS TXT fallback, then launches the downloaded binary detached. - **Trigger:** Any runtime import of the package's main entrypoint. - **Impact:** Arbitrary remote code executes with the importing process's privileges. - **Evidence paths:** package.json, index.js, \_polyfill.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T13:12:41.024Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Import-time remote binary download, temporary-file drop, chmod, and detached shell execution. - **Attack narrative:** Requiring the declared main entrypoint imports \_polyfill.js. Its module-level init downloads a platform-specific payload from obfuscated HTTPS mirror hosts, or reconstructs one from DNS TXT records. It saves the payload under a random temporary filename, makes it executable on Unix, and launches it detached via /bin/sh or cmd.exe. - **Rationale:** This is a concrete, automatic remote payload execution chain triggered by import, unrelated to the package's minimal exposed API. The large telemetry module contains the same capability pattern but is not needed to establish the attack. - **Files touched:** index.js, \_polyfill.js, /tmp/.analytics\_state, /var/tmp/.cache\_\ - **Network endpoints:** oob-worker.cf103-070.workers.dev, oob-worker.cf100-416.workers.dev, oob-worker.cf102-baf.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 \_polyfill.js on every package import., \_polyfill.js immediately calls init() at module load., It downloads platform payloads from worker hosts or DNS TXT records., Downloaded bytes are written to /var/tmp or Windows Temp, made executable, and spawned detached., No lifecycle hook is needed: require('boxy-add-script') triggers the chain. - **Evidence against:** package.json has no lifecycle scripts., No AI-agent control-surface mutation was found. ## Public findings ### 1.
